Description

Online nytron water content of matter and pure oil density analyze skid system
Technical field
The utility model belongs to water content in oil detection technique field, is related to online nytron water content of matter and pure oil is close Degree analysis skid system.
Background technique
The moisture content and pure oil density of online hydrocarbon (crude oil and its refining product) analyze demand, are widely present in The storage and transportation of the crude oil production process and finished product crude oil of oil-gas mining, handover, petrochemical industry/oil refining enterprise feedstock oil, such as crude oil and again (slag) oil and downstream refining product such as petrol and diesel oil and other light components refine the transmission & distribution handover, life of product, heavy oil, fuel oil etc. In the quality control of production and the process control of oil refining production.Since the component fluctuation of the different crude oil of the place of production, batch is very big, and Refining product, there is also the fluctuations of purity, density, and especially these oil products are all to be transported by way of sea-freight from the seller mostly To buyer, especially international oil product trade, and inevitably water ballast is mixed into shipment so that influencing magnitude Join or directly influence the quality of oil product.
In in the past few decades, the component and product due to oil product are monitored to the online moisture content of crude oil and its refining product Matter fluctuates and one as industry denounces greatly.Fluctuation of many online bearing analysis products applied in the market due to this component And it can not accurately measure the moisture content of oil product and finally end in failure.Due to the sensing of online bearing analysis product utilization Device is different and unified technique standard and criterion in none whole world up to now.Finally have to using on-line period+experiment The mode of room analysis carries out aqueous and oil density analysis, but whether this method is again equal by oil mixing with water in pipeline The problem of whether sample that is even and obtaining can really represent the truth of oil mixing with water inside pipeline, there are also take automatically Whether sample device uses enclosed sampling bottle also to influence whether finally to analyze quality;In addition a whole set of sampling system return line size compared with Small, impurity, wax deposition and the wall built-up being highly prone in crude oil product influence and cause pipeline blockage.Therefore, on-line period+reality of oil product It tests room analysis method in the actual operation process or there is very big uncertainty and noncontinuity operation, it is likely that because of people The result of final moisture content and density analysis is influenced for enchancement factors such as, equipment.
Therefore, online moisture content and pure oil density a kind of reliable, continuous, that be preferably minimized random error are found (quality) analytical equipment just becomes particularly important.
For a long time, each petrochemical industry, Petrochemical Enterprises used the online water cut monitor instrument of a large amount of imports, domestic crude oil, But effective, successfully application is never obtained, what this also became in industry one denounces greatly.The online water-containing machine of crude oil at present Microwave method is in the majority, and main representative producer has: mutually moving (the microwave absorption method of Phase-Dynamics and Agar company, the U.S. in the U.S. Microwave method (plug-in type representative) and U.S. Ai Mosheng under Roxar company microwave resonance principle based on full-bore (duct type) deisgn product;The online water content in oil analyzer of the condenser type principle of Canadian Delta C;There are also domestic with Jinzhou Brocade grinds the product of the radio frequency principle for representative.Several products in addition to the raw Roxar of Ai Mo are refined oil at home and production of hydrocarbons field There is extensive practice, but finally cannot all meet the needs of production.Thus, crude oil water containing analysis means use at most at present Or lab analysis is carried out with the way of distillation after automatic or manual sampling.But sampling+lab analysis is still difficult to accomplish reality When, accurately carry out Water in oil amount analysis, error is larger, this is because sampling when it is difficult to ensure that the sample got is exactly to manage The sample of practical aqueous distribution in road because mixing is critically important, no matter the aqueous situation of height all.Also, bring back to experiment Room carries out moisture content analysis, and the chemical examination time is long, and labor intensity, manpower and material resources consume more, dangerous environmental protection.And since crude oil produces Ground, component, quality is different, also results in online analyzer of water content and is difficult meet the needs of existing frequent switching.
Present bearing analysis instrument online on the market no matter import or homemade goods, do not have the automatic component of oil product and repair Orthofunction.When oil product change of component, that is, when density changes, the method required manually is sampled through testing The moisture content that room analysis obtains manually is returned to zero with instrument detection moisture content, to eliminate change of component to the shadow containing water gaging It rings.It carries out above and it is assumed that oil mixing with water condition is highly desirable.But in fact, oil mixing with water is difficult to protect Card is uniform.For so, if the oil product of oil refining enterprise very diversity, such as with regard to same root crude oil pipeline, by Zhenghai Refinery participates in the crude oil pipeline that pipeline reconciles and is tested, it was concluded that almost will more change oil every 1-2 days kind.This If sample, it is meant that will resample analysis and zeroing when changing oil product, just can guarantee the elimination of oil product components influence, this In do not consider that just same 100,000 cubes of petroleum tank abhiseca and bottom component change influence to measurement also.But practical this oil The variation of product component is difficult to track, and the way of this frequent adjustment meter parameter is that oil refining enterprise is unacceptable.
In consideration of it, special propose the utility model.

Specific embodiment
The embodiments of the present invention are described in detail below in conjunction with embodiments and examples, but ability Field technique personnel will be understood that following embodiments and embodiment are merely to illustrate the utility model, and be not construed as limitation originally The range of utility model.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative labor Every other embodiment obtained under the premise of dynamic, fall within the protection scope of the utility model.The person that is not specified actual conditions, presses The condition that more solito condition or manufacturer suggest carries out.
In a first aspect, providing a kind of online nytron water content of matter and the analysis of pure oil density at least one embodiment Skid system, including the sampler being measured on medium pipeline, the bearing analysis being connected with sampler sled master is arranged in Body and data collection system;
Bearing analysis sled main body includes being sequentially connected the filter device connect, sampling pump, density measuring equipment and aqueous Analyzer;
The density measuring equipment and analyzer of water content are electrically connected the data collection system.
It should be understood that above-mentioned " hydrocarbon " includes crude oil and its refining product, for specific crude oil and its Concrete type the utility model of refining product is not particularly limited.
It should be noted that above-mentioned " data collection system " is data acquisition, analysis and output system, the acquisition of abbreviation data System.
Since in June, 2015, utility model people has found that the Roxar under U.S. Ai Mosheng house flag has a microwave resonance The online analyzer of water content of the duct type design with heavy wool product density of fraction zero offset capability of principle, it is online close in conjunction with one Degree meter can be realized as oil product change of component and realize automatic compensating approach to density.But as previously mentioned, in practical applications, encountering When frequent oil product change of component, which needs frequently adjustment meter parameter, this is that oil refining enterprise is unacceptable.Therefore exist Almost online bearing analysis is at the state of stopping before Roxar popularization microwave resonance technology+auto zero function.Further It says:
It will be appreciated by persons skilled in the art that in current online analyzer of water content, it is no matter former using which kind of physics Reason, being provided to find different moments flows through the oil mixing with water permittivity ε of pipelinemix.And it can be seen using Brueggemann equation Out, moisture content β not only with oil mixing with water permittivity εmixIt is related, it goes back and pure oily permittivity εoilWith the dielectric constant of water εwaterIt is related.Brueggemann equation is as follows:
In formula, β is moisture content, εmixTo mix dielectric constant, εwaterFor the dielectric constant of water, εoilIt is normal for pure oily dielectric Number.
It is (i.e. close to carry out component to oil product by the method for manual sampling when driving to come into operation for analyzer under normal circumstances Degree) and instantaneous crude oil water content analysis, remember the original moisture content detected value of lower sampling moment instrument, will analyze get it is close Angle value configuration inputs water-containing machine electronic unit and is set by the deviation between manual analysis water cut value and the original reading value of instrument Set zero shift value;This is carried out under the premise of current oil product component.Due to the dielectric constant of oil product and the correspondence of density Relationship can be easily found by being implanted into the database of electronic unit, the dielectric constant including water.Thus, it is supposed that oil product component is not In the case where change namely density and pure oily dielectric constant it is constant in the case where, then being by the moisture content that instrument detected It will not be influenced by change of component.And moisture content output accuracy just only has relationship with oil mixing with water degree.But with regard to one 10 For ten thousand cubes of petroleum tank, after cutting water by the standing of a period of time, actually the top and bottom density components of tank are not yet It can be identical.Therefore, the accuracy of reading of actual instrument will lead to the variation of pure oily dielectric constant because of oil product component difference, that In this case, the precision of the original reading value of the moisture content of output is difficult to that the number aqueous due to oil water mixture be ensured of Cause mix change in dielectric constant still as it is pure oil change in dielectric constant caused by oil mixing with water dielectric constant variation? here It is assumed that oil mixing with water is uniform.But in fact especially in ultralow moisture content (when moisture content is lower than ± 0.2%), Grease is it is difficult to ensure that being mixed thoroughly.
And the online water-containing machine of Roxar microwave resonance has oil product component zero offset capability auto zero skill in other words Art.It is combined by the on-line densimeter being mounted near analyzer of water content upstream or downstream with one, passes through oil mixing with water The real-time measurement of density, to obtain pure oil density, Jie of pure oil is obtained by pure oil density under the premise of known aqueous rate Electric constant, to obtain moisture content further through Brueggemann equation, moisture content is used as again to be calculated with real-time oil mixing with water density Pure oil density out just exports measurement of water ratio value in this way by former and later two moisture content fiducial values < 0.001, namely by with Calculating between lower two formula formulas (1) and formula (2) can be achieved with auto zero technology, to guarantee measurement of water ratio not by oil The influence of product change of component.
In formula, β is moisture content, εmixTo mix dielectric constant, εwaterFor the dielectric constant of water, εoilIt is normal for pure oily dielectric Number, ρoilTPFor the initial value of the density of pure oil, ρmixFor hybrid density, ρwaterFor the density of water.
Specific steps can parse are as follows:
Initialization:
Frequency (T, P, the ρ of mixture temperature, pressure, density and mixture are obtained from different sensorsmix, fmix);
Calculate mixing dielectric constant (εmix);
Calculate the density being lauched in working condition pressure and temperature and dielectric constant (ρwater, εwater);
Assuming that under working temperature and pressure condition moisture content and oil density initial value (β, ρoilTP);
Iteration:
β value before storage;
Calculate εoil=f (ρoilTP);
Calculate β=f (εmix, εoil, εwater)
Calculate ρoilTP=f (ρmix, β, ρwater)
Above step is repeated until the difference < 0.001 of the β value of previous and new calculating.
In brief, bearing analysis product of the Roxar with Autozero function be by (2) two formula of formula (1) and formula, Ensure that analyzer of water content is able to achieve to heavy wool during constantly initializing, be iteratively repeated under " ultrahigh speed " operation state Highly reliable, high-precision measurement when product component changes.Above is exactly Roxar auto zero technology and we are entire The basis of crude oil water containing analysis performance guarantee.
However, the online analyzer of water content of Roxar is lower to oil mixing with water requirement, the water body diameter in general recommendations oil is less than Instrument latus rectum 1/10 is the lowest performance marked in the data that can guarantee.Especially when ultralow aqueous, due to weight viscosity of crude Difference, in identical ultralow moisture content (assuming that water cut value is 0.065%), due to the difference of oil viscosity height, in vacation If oil and water zonation form and different under moisture content, it is different that this will lead to water-containing machine original output.So in very wide original Oil density range, such as Zhenghai refinery, pure oil density is from 720kg/m3To 930kg/m3, on the one hand pass through above-mentioned auto zero Influence when technology is able to solve change of component to measurement, on the other hand it still will receive oil property i.e. oil and water zonation form Different influence still needs to calibrate instrument fan-out capability when density fluctuation range is larger, that is, re-scales zero, This just gives the practical application in industry of analyzer of water content to be provided with a big obstacle.Ultralow moisture content especially within ± 0.2% In the case of, the variation of instrument original output can be fluctuated between 0.9% to 0.2%, but practical moisture content is not so high, can Can also there was only 0.05% or 0.025%, because the resolution ratio of the way of distillation is just 0.025%.Which increases instrument to contain ultralow Measurement error under water rate.
Based on this, utility model people develops a set of data acquisition software, i.e., is segmented correcting mode using density to eliminate Oil and water zonation form is influenced caused by measurement result, and a point density section used by this sets of data acquisition system software is repaired Positive method enables to the performance of the online bearing analysis of crude oil when the oil density wide swings under ultralow moisture content to obtain To guarantee.It enables to using Roxar band using this sets of data acquisition system software and modification method of the utility model Heavy wool product density of fraction zero offset capability (Autozero component debugging functions) realizes more have after line analyzer of water content Effect ultralow containing underwater industrial application.
