Method, device and system for joint measurement of emulsification ability and emulsion stability of rotating liquid

technical field

This paper relates to the field of petrochemical industry, especially a method, device, system, computer equipment and storage medium for joint measurement of emulsification ability and emulsion stability of rotating liquid.

Background technique

The test and evaluation of oil-water emulsifying ability and emulsion stability have been widely used in food, medicine, chemical synthesis and other fields. For example, in the field of petroleum development, especially in the process of chemical flooding with surfactants, the evaluation of oil-water emulsifying ability and emulsion stability plays a crucial role in improving the research and application of chemical flooding theory and technology.

In the past, the milk-making method for the stability test of oil-water emulsions was mainly carried out by hand shaking. The test tube was shaken to make the oil-water vibrate up and down to form an emulsion. This method is simple and convenient. However, the hand-cranking method is difficult to be scientifically standardized, the influence of human factors is large, the repeatability of the experimental results is poor, and the temperature of the emulsification process cannot be controlled. There is also a mechanical shaking method to evaluate the emulsifying ability, which can precisely control the emulsifying conditions and the temperature during the emulsifying process. Although the emulsion stability evaluation method based on mechanical shaking overcomes the shortcomings of the hand shaking method, this method still has the following shortcomings: (1) the emulsification process cannot be judged, only the final emulsification result; (2) the test tube is seriously sticky during the shaking process, which affects the accuracy Reading; ③ After the experiment is completed, the emulsification band can be read after a period of stillness, which is not the original emulsification amount, and the emulsification may break during the waiting process; ④ The external input energy of the traditional mechanical milk making process is often constant, which makes it impossible to evaluate the emulsification The minimum disturbance energy that occurs and the influence on emulsification with the change of external energy.

In addition, the prior art also adopts the ultrasonic emulsifying method to evaluate the oil-water emulsifying ability. However, due to the characteristics of ultrasonic conduction and the complex factors affecting energy attenuation, it is impossible to accurately control and measure the ultrasonic energy and its distribution in the emulsification tube, resulting in uncertainty in the oil-water emulsification position. Using it to evaluate the emulsion stability, the joint measurement of oil-water emulsifying ability and emulsion stability cannot be achieved.

Aiming at the problem that the current milk production method cannot accurately evaluate the oil-water emulsification ability and emulsion stability, a method, device and system for joint measurement of the emulsification ability and emulsion stability of a rotating liquid are required.

It should be noted that the joint measurement method of rotating liquid emulsification ability and emulsion stability in this paper can be used in the petrochemical field, and can also be used in any field such as medicine, pharmacy, chemistry, etc. The application field of the device and the system is not limited.

As shown in Figure 1, a flow chart of a method for joint testing of rotating liquid emulsification ability and emulsion stability according to the embodiment of this paper, which specifically includes the following steps:

Step 101, inject the first liquid phase and the second liquid phase into the emulsification test tube respectively, and obtain the initial height of the first liquid phase in the emulsification test tube. In this step, the emulsification test tube is a device used for containing the first liquid phase and the second liquid phase in the emulsification test device. Wherein, the emulsification test tube can be transparent, which is convenient to observe the height change of the first liquid phase and the second liquid phase during the emulsification and demulsification process, as well as the height change of the emulsification zone.

In some embodiments of the present specification, the first liquid phase and the second liquid phase are two liquids that are immiscible under normal conditions. The first liquid phase may be an oil phase, including but not limited to crude oil containing different components, and the second liquid phase may be an aqueous phase, including but not limited to water containing different minerals and surfactants.

In this step, the second liquid phase can be injected into the emulsification test tube first, and then the first liquid phase can be injected. That is, the water phase was injected into the emulsification test tube first, and then the oil phase was injected. And record the initial height of the oil phase in the emulsification test tube. This initial height corresponds to the amount of the oil phase injected into the emulsification test tube, and the initial height can be used as a reference height of the first liquid phase for calculating the emulsification rate and the demulsification rate in subsequent steps.

Step 102: Calculate the emulsification rate of the second liquid relative to the first liquid phase at multiple rotation speeds according to the initial height of the first liquid phase and the unemulsified height of the first liquid phase at each rotation speed of the rotation module . In this step, the rotation module is a part of the rotation module in the emulsification test device of the embodiment herein, and the rotation module is used to cause the first liquid phase and the second liquid phase in step 101 to rotate, and in the first liquid phase A stable shear flow field is formed at the phase interface with the second liquid phase. The first liquid phase and the second liquid phase are further emulsified. In some embodiments of the present specification, the first liquid phase and the second liquid phase in a rotating state may be referred to as rotating liquids. A detailed description of the rotating module and the emulsification testing device can be found in FIG. 9 . The rotation module in this step is the rotation module in FIG. 9 . The unemulsified height of the first liquid phase can be understood as the remaining unemulsified height of the first liquid phase in the emulsification test tube, ie, the remaining height of the first liquid phase. The rotation module can provide different rotational speeds, and by recording the un-emulsified height of the first liquid phase and the initial height of the first liquid phase under the non-stop rotational speed, the emulsification rate of the second liquid relative to the first liquid phase at different rotational speeds can be calculated. .

Step 103: Calculate the first liquid phase and the second liquid phase at multiple times according to the initial height of the first liquid phase and the heights of the first liquid phase at multiple times after the rotation module is stopped The demulsification rate of the formed emulsion. In this step, with the stop of the rotating module in the emulsification test tube, the emulsification state of the first liquid phase and the second liquid phase will also stop. At several moments after the rotation module stops, the previously emulsified first liquid phase in the emulsification test tube will undergo demulsification, the first liquid phase will precipitate, and the height of the first liquid phase in the emulsification test tube will gradually increase. Within a certain time range, the height of the first liquid phase is different at different times. When the time reaches a certain time, the height of the first liquid phase will tend to be stable and will not change.

Step 104: Determine the emulsification coefficient of the second liquid relative to the first liquid phase according to the emulsification ratio of the second liquid relative to the first liquid phase at the multiple rotational speeds. In this step, each rotation speed corresponds to an emulsification ratio, and the emulsification coefficients of the second liquid phase and the first liquid phase can be determined according to multiple emulsification ratios of the second liquid to the first liquid phase corresponding to the rotation speed at multiple times. Among them, the emulsification coefficient can evaluate the emulsification ability of the second liquid relative to the first liquid phase. Emulsifying ability can be understood as the ease with which the first liquid phase and the second liquid phase form an emulsion.

Step 105: Determine the demulsification coefficient of the emulsion according to the demulsification rate of the emulsion formed by the first liquid phase and the second liquid phase at the multiple times. In this step, each moment corresponds to the demulsification rate of the emulsion formed by the first liquid phase and the second liquid phase, and the first liquid phase and the second liquid phase can be determined according to multiple demulsification rates corresponding to multiple moments. The demulsification coefficient of the emulsion formed by the liquid phase in this state. Among them, the demulsification coefficient can evaluate the stability of the emulsion formed by the first liquid phase and the second liquid phase. Specifically, the smaller the value of the demulsification coefficient, the stronger the stability of the emulsion.

FIG. 2 is a flow chart of a method for determining the height of the first liquid phase and the second liquid phase injected into the emulsification test tube according to the embodiments herein.

其中，h_ow为测试条件下第一液相与第二液相的界面高度；h_ow为标准条件下第一液相与第二液相的界面高度；η_ws为标准条件下第二液相的粘度，η_w为测试条件下第二液相的粘度；C为油水界面剪切力相似系数。Step 201: Determine the amount of the first liquid phase and the second liquid phase according to the following formula:

_Wherein , how is the interface height of the first liquid phase and the second liquid phase under the test conditions; _{how is the interface height of the first liquid phase and the second liquid phase under the standard conditions; η ws is} the second liquid phase under the standard conditions. , η _w is the viscosity of the second liquid phase under the test conditions; C is the oil-water interface shear force similarity coefficient.

The standard conditions are experimental conditions under preset standard conditions. The standard conditions include: standard temperature, standard interface height between the first liquid phase and the second liquid phase, the viscosity of the second liquid phase or the tested active agent solution, and the like. In some embodiments of this specification, the standard temperature may be 25° C., 30° C., etc., and the standard interface height between the first liquid phase and the second liquid phase may be 5 cm, 7 cm, 8 cm, etc.; the second liquid phase or The viscosity of the tested active agent solution is 0.8 etc. The test conditions are the conditions of the actual experiment, including: the test temperature, the viscosity of the second liquid phase or the tested active agent solution, etc. For example, the test condition temperature is 40°C, the viscosity of the second liquid phase at the test temperature is 0.6, the standard temperature is 25°C, the standard interface height between the first liquid phase and the second liquid phase is 5 cm, and the If the viscosity is 0.8, and the similarity coefficient C of the shear force between the first and second liquid phases is 1, then the interface height between the first liquid phase and the second liquid phase under the test conditions can be determined to be 3.75 cm according to the formula.

Step 202: Determine the initial height of the first liquid phase according to a preset ratio of the first liquid phase to the second liquid phase and the interface height. For example, the preset ratio of the first liquid phase to the second liquid phase is 4:1, and the initial height of the first liquid phase can be determined according to the interface height of the first liquid phase and the second liquid phase calculated in step 201 . For example, if the height of the interface between the first liquid phase and the second liquid phase is calculated to be 3.75 cm in step 201, then according to the preset ratio, the height of the first liquid phase can be determined to be 0.94 cm. In some embodiments of this specification, the preset ratio of the first liquid phase to the second liquid phase is preset, and can also be adjusted in real time according to actual experimental conditions. The application does not limit the interface height between the first liquid phase and the second liquid phase.

FIG. 3 is a flow chart of a method for calculating the emulsification rate of the second liquid relative to the first liquid phase at multiple rotational speeds according to an embodiment of this document. Specifically include the following steps:

Step 301: Control the rotation of the rotation module in the emulsification test tube according to the preset rotation speed, and determine the un-emulsified height of the first liquid phase at the rotation speed after each adjustment of the rotation speed of the rotation module. In this step, the rotation control device can control the rotation module to rotate at a certain speed, and the rotation control device can also control the rotation module to speed up at a certain speed, so that the first liquid phase and the second liquid phase in the emulsification test tube are in different emulsification state. For example, the rotation control device may control the rotation module to rotate at an initial rotation speed of 400 rpm, and increase the rotation speed in steps of 50 rpm each time until the rotation speed reaches 800 rpm. In this step, a camera can be used to monitor and obtain the change of the emulsification amount of the first liquid phase and the second liquid phase in the emulsification test tube, and wait for the emulsification amount of the first liquid phase and the second liquid phase to stabilize at each rotation speed Then, record the height of the unemulsified first liquid phase at this rotational speed. Wherein, the camera includes but is not limited to one of high-speed macro cameras, laser cameras, etc. or any combination thereof. In this application, the initial rotational speed, rotational speed increment and termination rotational speed of the rotation module are not limited to the values described in the embodiments of this step, and the initial rotational speed, rotational speed increment and termination rotational speed of the rotational module in this application can be any other reasonable range The numerical value within is not limited in this application.

Step 302, according to the initial height of the first liquid phase and the un-emulsified height of the first liquid phase at each rotational speed, use the following formula to calculate the emulsification rate of the second liquid relative to the first liquid phase under each angular velocity:

其中，wi为旋转模块的角速度，E₀(wi)为角速度wi对应的乳化率，h_o0为所述第一液相的初始高度，h_oi(wi)为角速度wi对应的第一液相的未乳化高度。在本步骤中，第一液相的初始高度为最初加入到乳化测试管中的第一液相的高度。

Wherein, wi is the angular velocity of the rotating module, E ₀ (wi) is the emulsification ratio corresponding to the angular velocity wi, h _o0 is the initial height of the first liquid phase, and h _oi (wi) is the first liquid phase corresponding to the angular velocity wi. Unemulsified height. In this step, the initial height of the first liquid phase is the height of the first liquid phase initially added to the emulsification test tube.

The formula in this step represents the ratio of the variation of the emulsification height of the first liquid phase to the initial height of the first liquid phase under different angular velocities. Wherein, as the rotational speed increases, the degree of emulsification of the first liquid phase is greater, the unemulsified height h _oi (w) of the first liquid phase is smaller, and the emulsification height h _o0 -h _oi (wi) of the first liquid phase is smaller. is larger, the larger the proportion of the emulsified height of the first liquid phase to the initial height h _o0 is, that is, the larger the emulsification rate.

FIG. 4 is a flow chart of a method for calculating the demulsification rate of the emulsion formed by the first liquid phase and the second liquid phase at multiple times according to an embodiment of the present invention.

Step 401, when the rotation module reaches the maximum rotational speed, obtain the unemulsified height of the first liquid phase. In this step, when the rotational angular velocity of the blades in the rotation module reaches the upper limit value, the unemulsified height of the first liquid phase is obtained, that is, the remaining height h _ne of the first liquid phase in the emulsification test tube. In this step, the maximum rotational speed is set to 800 rpm, and when the rotation module in the emulsification test tube rotates to 800 rpm, the unemulsified height of the first liquid phase is obtained. In this step, the camera is used to continuously record the height of the first liquid phase at different times, and when the height of the first liquid phase will not change after a certain period of recording, the recording is stopped.

In this step, h _ne is the height of the first liquid phase at the initial moment after the rotation of the rotating module stops. That is, the initial height of the first liquid phase after the emulsification process of the first liquid phase and the second liquid phase in the emulsification test tube is completed. For example, after the emulsification process of the first liquid phase and the second liquid phase is completed, the initial height of the first liquid phase is 0 mm, indicating that after the emulsification process is completed, there is no clear first liquid phase in the emulsification test tube temporarily, and the first liquid phase still remains. Not separated from the emulsification bands produced during emulsification.

Step 402: Control the rotation module in the emulsification test tube to stop rotating, and obtain the height of the first liquid phase at multiple times in the static state. When the rotating module stops rotating, the first liquid phase and the second liquid phase in the emulsification test tube gradually tend to a static state from a high-speed rotation state. In some embodiments of the present specification, after the process of emulsification of the first liquid phase and the second liquid phase in the test tube from a high-speed rotation state to a stop of rotation, based on the influence of liquid inertia, etc., it is necessary to wait for a very short period of time before emulsification. The liquid in the test tube is truly still. Taking the whole liquid in the emulsification test tube in a static state as the first time, record the height of the first liquid phase and the dynamic changes of the emulsification zone at multiple times from the first time. In the moment after resting, as time increases, the height of the first liquid phase will gradually increase, the height of the emulsification zone will gradually decrease, and the first liquid phase will gradually separate from the emulsification zone. In some embodiments of the present specification, the height of the first liquid phase at a plurality of times in the stationary state is represented by h _do (t). In this step, h _do (t) is the height of the first liquid phase at multiple times after the rotation of the rotating module is stopped. After the rotation of the rotating module stops, the first liquid phase in the emulsification test tube is gradually separated from the emulsification belt, and the demulsification phenomenon begins to occur. The height h _do (t) of the first liquid phase will gradually increase over time.

Step 403: Determine the demulsification amount of the first liquid phase at multiple times according to the un-emulsified height of the first liquid phase and the heights of the first liquid phase at the multiple times. In this step, the demulsification amount of the emulsion formed by the first liquid phase and the second liquid phase is: the difference between the height of the first liquid phase and the unemulsified height of the first liquid phase at multiple times, which can be determined by h _do (t)-h _ne representation.

In this step, h _do (t)-h _ne represents the height increment of the first liquid phase during the demulsification process. The larger the value of h _do (t)-h _ne , the greater the degree of demulsification of the first liquid phase, and the higher the degree of separation between the first liquid phase and the second liquid phase. Conversely, the smaller the value of h _do (t)-h _ne , the smaller the degree of demulsification of the first liquid phase, and the smaller the degree of separation between the first liquid phase and the second liquid phase.

Step 404: Determine the initial emulsified amount of the first liquid phase according to the initial height of the first liquid phase and the un-emulsified height of the first liquid phase. In this step, the initial emulsification amount can be understood as the emulsification process in which the first liquid phase undergoes rotational acceleration, and its height gradually decreases from the initial height to the unemulsified height at the maximum rotational speed. The initial emulsification amount of the first liquid phase is the difference between the initial height of the first liquid phase and the unemulsified height, which means the emulsification amount of the first liquid phase after emulsification, that is, the initial emulsification amount, which is represented by h _0i -h _ne .

表示乳液的破乳率。其中，h_ne为旋转模块停止转动后，初始时刻下所述第一液相的高度，h_do(t)为静止状态多个时刻的第一液相的高度，h_0i为第一液相的初始高度。Step 405: Determine the demulsification rate of the emulsion according to the ratio of the demulsification amount to the initial emulsification amount. In this step, use the formula

Indicates the demulsification rate of the emulsion. Wherein, h _ne is the height of the first liquid phase at the initial moment after the rotation module stops rotating, h _do (t) is the height of the first liquid phase at multiple moments in the stationary state, h _0i is the height of the first liquid phase Initial height.

可以计算在最小角速度和最大角速度范围内，每个角速度与其对应的乳化率的乘积的累加和。其中，E_o(ω_i)为第i个角速度对应的乳化率；ω₂为所述多个角速度中的最大角速度；ω₁为所述多个角速度中的最小角速度。Step 501: Determine the curve integral of the emulsification rate of the second liquid relative to the first liquid phase with the rotational speed at multiple rotational speeds. The emulsification rate of the second liquid relative to the first liquid phase at each rotational speed can be determined by the method of step 302, but each rotational speed in step 302 is a limited number of rotational speeds set in the experiment, that is, the rotational speed is a discrete rotational speed in the time domain. . In order to obtain a more accurate emulsification coefficient of the first liquid phase, it is necessary to further obtain the emulsification ratio of the second liquid relative to the first liquid phase at more rotational speeds. In this step, the curve integration method is used to calculate the emulsification rate of the second liquid relative to the first liquid phase at all rotation speeds in the range of the maximum rotation speed and the minimum rotation speed among the multiple rotation speeds in step 302 . Figure 11 is a graph showing the relationship between the emulsification ratio and the rotational angular velocity. The coordinates formed by multiple rotational speeds and their corresponding emulsification ratios in the figure are connected to form a complete curve. Use the curve integral formula

The cumulative sum of the products of each angular velocity and its corresponding emulsification ratio within the range of the minimum angular velocity and the maximum angular velocity can be calculated. Wherein, E _o (ω _i ) is the emulsification ratio corresponding to the ith angular velocity; ω ₂ is the maximum angular velocity among the multiple angular velocities; ω ₁ is the minimum angular velocity among the multiple angular velocities.

Step 502, according to the curve integral, use the following formula to determine the emulsification coefficient:

其中，EI为所述乳化系数，

In this step, ω ₂ -ω ₁ is the rotational speed difference between the maximum rotational speed and the minimum rotational speed, E _o,st is the reference emulsification rate, which means that the relationship between rotational speed and emulsification rate increases linearly at each angular velocity. The benchmark emulsification rate can be viewed as a linear function, for example, the minimum angular velocity is 400 rpm and the maximum angular velocity is 800 rpm. When the angular velocity is at the minimum, the emulsification rate is 0; when the angular velocity is at the maximum angular velocity, the emulsification rate is 100%, and the angular velocity is the independent variable. E _{o, st} means that the emulsification rate increases with the rotational speed and shows a linear growth relationship. In this step, the larger the value of the calculated emulsification coefficient, the stronger the emulsification ability of the emulsifier.

Figure 6 is a flow chart of a method for determining the demulsification coefficient of an emulsion according to an embodiment of the present invention. Specifically include the following steps:

可以计算在0时刻和t_s时刻范围内，每个时刻与其对应的破乳率的乘积的累加和。其中，D_o(t)为第t个时刻对应的破乳率；t_s为所述多个时刻中的第s个时刻；0时刻为所述多个时刻中的初始时刻。Step 601: Determine the curve integral of the demulsification rate of the emulsion at multiple times with the times. The demulsification rate of the emulsion at multiple times can be determined by the method of step 402, but the multiple times in step 402 are a limited number of times set in the experiment, that is, discrete times. In order to obtain a more accurate demulsification coefficient, it is necessary to further obtain the demulsification rate of the emulsion at more times. In this step, the curve integration method is used to calculate the demulsification rate of the emulsion at all times within the range of the maximum time and the minimum time among the multiple times in step 402 . Figure 12 shows the relationship between the demulsification rate and the rotational speed. The coordinates formed by the multiple moments in the figure and their corresponding demulsification rates are connected to form a complete curve. Use the curve integral formula

The cumulative sum of the products of each time and its corresponding demulsification rate in the range of time 0 and time t _s can be calculated. Wherein, D _o (t) is the demulsification rate corresponding to the t-th time; t _s is the s-th time among the multiple times; and time 0 is the initial time among the multiple times.

Step 602, according to the curve integral of the demulsification rate with the time, the demulsification coefficient is determined by the following formula:

其中，DI为所述破乳系数,

为旋转模块停止转动后静止状态多个时刻下乳液的破乳率随所述时刻的曲线积分，t为旋转模块停止转动后静止状态的，D_o(t)为时刻t对应的破乳率；t_s为所述多个时刻中的第s个时刻；D_o,st(t)为基准破乳率。

Wherein, DI is the demulsification coefficient,

In some embodiments of this specification, D _o,st (t) represents that at each moment, the relationship between time and demulsification rate increases linearly. D _o,st (t) can be regarded as a linear function, for example, the minimum time is 0 minutes and the maximum time is 60 minutes. The minimum time is the starting time when the rotating module in the emulsification test tube stops rotating and is in a static state. At the minimum time, the emulsification rate is 0; when it is at the maximum time, the emulsification rate is 100%, and the time t is the self-time t. variable, when the time is in the interval of [0,60] minutes, the demulsification rate increases linearly, and the emulsification rate is a dependent variable, D _o,st (t) means that the demulsification rate increases with time and changes linearly. relation. In this specification, the emulsification coefficient and demulsification coefficient are used as indicators to evaluate the emulsification ability and emulsion stability of the tested system. performance. The larger the emulsification coefficient EI, the stronger the emulsifying ability of the tested system; the smaller the demulsification coefficient, the stronger the stability of the tested emulsion.
