One, the analysis of oil body factor:
1, water
During refinery is produced, produce in the oil body pipeline of outlet, because distil process itself contains more water in the pipeline oil body at device.The main forms that water exists is a free water, and the sub-fraction emulsified water is arranged simultaneously.
From installing next oil product, can be temporary in the semi-manufacture jar usually.During semi-manufacture jar temporary, at the bottom of W/O can be deposited in to a certain extent according to the length of the residence time jar, but jar in oil still contain micro-moisture.
In petroleum products blending, semi-manufacture oil may be directly from device, also may be from the semi-manufacture jar.Which kind of mode no matter, the micro-moisture in the oil is always inevitable, and directly the water-in-oil content from device is a lot, contains a certain amount of moisture from the oil product of semi-manufacture jar.
In the index of dispatching from the factory of the gasoline product of GB regulation, moisture should be greater than 100ppm, and in the semi-manufacture oil in process of production, the content of moisture is higher than this far away.And water content in oil is alkalescent or strong basicity usually.
2, impurity
Impurity in the oil product mainly comes from catalyst fines in the device, pipeline inwall iron rust etc.Directly in the oil product from device, impurity content is higher, if in the semi-manufacture jar temporary a period of time, at the bottom of impurity can be deposited in jar significantly.
3, bubble
Oil product is moving, in the transfer process, because the motion of itself and the fluctuation situation of pipeline internal pressure, and the fluctuation situation of temperature, can produce more bubble.
4, temperature
Device comes the oil product temperature higher usually, be generally 30～50 ℃, and semi-manufacture jar temperature is usually near environment temperature.
Two, the oil body factor is to the influence of near infrared detection:
1, the influence of water
Near infrared detection principle fundamentally is to produce owing to the near infrared spectrum that contains H (hydrogen) group in the organism absorbs.Water contains H (hydrogen) group H-O, thereby may influence the measurement of near-infrared analyzer.In the practical application, probe is can not influence probe measurement by the emulsified water in the oil product only, because the emulsified water content in the oil product is very low under the situation of cleaning.But because the sapphire window possess hydrophilic property (comparing) on the near-infrared analysis instrument probe with the character of oil product own, therefore still easily from oil, separate and be attached on the sapphire window of probe, time has been grown, may form the very thin moisture film of one deck on the probe, thereby on slight extent, influence the detection of near-infrared analysis instrument probe.More serious situation is may have a large amount of free waters in a certain stage in the oil product to come, and is a large amount of attached on the sapphire window of popping one's head in, thereby has a strong impact on the measurement of probe.
2, impurity effect
Impurity may arrive the sample detection space of probe along with the motion of oil product, and stops at detecting head surface, thus the measurement of influence probe.
3, influence of air bubbles
In the sample detection space of probe, because the existence of bubble causes thickness of sample to reduce, thereby has a strong impact on the accuracy of measurement.
4, Temperature Influence
The conversion of temperature can make spectrum be offset along wavelength direction.Temperature raises, and spectrum moves to left; Temperature reduces, and spectrum moves to right.Because moving of spectrum generation wavelength direction, thereby the accuracy that influence is measured.
Three, pretreatment system principle of design:
In order to guarantee the accurate measurement of near-infrared analyzer, must guarantee that the oil product that detects the space through probe is clean and does not have bubble.Therefore, when considering the design sample pretreatment system, accomplish to dewater as far as possible, the removal of impurity, remove bubble, and make the oil product constant temperature that detects the space through probe as far as possible.For this reason, it is neat to install dehydrator, filtrator, bubble trap and constant temperature in sample pretreatment system.
Four, sample pretreatment system structure:
According to the above sample pretreatment thought of discussing, can make the supporting sample pretreatment system of on-line nir system that satisfies actual refinery process control and petroleum products blending production needs.The fluid factor of oil body in the pipeline of discussing at the front can design and comprises following device and structure, with the cleaning that guarantees the oil property after the pre-service with stable, thereby guarantee the accurate measurement of near-infrared analysis instrument probe.Main device and structure comprise: as depicted in figs. 1 and 2: quick loop 1, quick loop sampling pump 11, bubble trap 13, grade one filter 14, pre-service reduction valve 24, tensimeter 25, water cooler 26, alternative secondary filter 29, dehydrator 30, analyte capture jar 19, thermostat 34, adjustable rotor flowmeter 35, teletransmission tensimeter 25, recycling can 22, recovery pump 23 etc.; Process Control System 8 among Fig. 1 is connected to the scene, and the left side of on-line nir system 5 is power-on self-test and positive draft device among Fig. 2, and the whirlwind cooling is carried out in the periphery, and power-on self-test is communicated with instrument wind with the positive draft device by valve.
Five, hardware description, as depicted in figs. 1 and 2:
1. quick loop: the purpose in loop 1 is to obtain the process sample fast from the process line sampled point fast, and it is transferred to sample detection demand position fast, thereby reduces as much as possible the detection delay time of Process Control System.In the practical application, quick loop 1 can adopt 1/2, and " steel pipe, its pipeline should not surpass 30m, and is short as much as possible in practical ranges.
2. quick loop pump: only install quick loop 1 in the process sample region, may since fast the two ends in loop 1 do not have the former of enough pressure reduction thereby cause the transfer velocity of sample of process check point very slow, thereby cause very big system to delay, influence system control performance.For addressing this problem, adding quick loop pump on quick loop 1 is that sampling pump 11 is necessary.The selection principle of loop pump 11 is to guarantee that the sampling in quick loop 1 is steady fast, do not have pressure surge (because the pressure surge meeting causes a large amount of bubbles), and sampled fluid is continuous, and speed can be very not fast, but can not be very slow.Given this, suggestion selects gear-type pump to be advisable.In conjunction with the 1st, the 2nd point, be controlled at 30s and be advisable the actual sample time in loop 1 fast, and loop flow 300～800L/h is advisable fast.
3. bubble trap: the effect of bubble trap 13 is by the minor axis bypass, makes can not enter pretreatment unit by the bubble in the process sampling fluid of quick loop pump 11, but draws from the minor axis bypass.
4. grade one filter: grade one filter 14 is installed on the quick loop 1; the effect of grade one filter 14 is to stop that the large granular impurity (for example pipeline iron rust etc.) in the process line enters pretreatment system; block Φ 6 stainless-steel tubes of pretreatment system or damage cartridge or dehydrator core, thereby play the pretreated effect of protection.
5. pre-service reduction valve: pre-service reduction valve 24 is the process sample enters pretreatment system from quick loop 1 critical points.The oil product that flows in the pretreatment system needs stable and suitable pressure, because will consider the factor of three aspects: the one, the pressure surge meeting in the pretreatment system causes and produces bubble in the oil product; The 2nd, pressure surge may cause damage to secondary filter 29 and dehydrator 30 and on-line nir system 5 probes; The 3rd, the pressure surge meeting influences probe measurement.3 considerations for this reason, pretreatment system need be installed reduction valve 24 (pressure maintaining valve), and the oil product pressure in the control pre-service usually can be at 0.05～0.1Mpa in suitable scope.In the design in quick loop 1, fast aspect the selection of selection, the pre-service reduction valve 24 of loop pump 11, need consider according to the pressure matching relationship.
6. tensimeter: the tensimeter 25 after the pre-service reduction valve is used for the on-the-spot sample strain that shows after the pre-service reduction valve 24, helps on-the-spot artificial reduction valve 24 apertures of adjusting, and guarantees that pressure in the pretreatment system is in suitable scope.Usually reasonably the pressure limit of pretreatment system can be at 0.05～0.1Mpa.
7. water cooler: the oil product temperature in the process line may be than higher, for example 40～60 ℃; The effect that water cooler 26 is installed mainly is to have considered two following factors: the one, and the oil product temperature in the process line is too high, needs with water cooler it to be cooled to below 30 ℃; The 2nd, by reducing the oil body temperature significantly, help free water and emulsified water in the oil body to be condensed into bigger water droplet, thereby help to improve the water removal effect of dehydrator 30.
8. alternative filtrator: the secondary alternative filtrator 29 in pretreatment system is one of core devices in the pretreatment system, all impurity in the oil product and bulky grain water droplet all are blocked and are deposited in filter bottom (or directly emitting) during by cartridge at sample, thereby guaranteed to enter oil product clean of follow-up unit, guaranteed the accuracy of probe measurement.Alternative filtrator 29 adopts the working method of the using and the reserved, guarantees can drop into the standby filtrator of another at once, and can easily it be pulled down cleaning or the cartridge that more renews when a filtrator during because of dirty inefficacy.The strainability of cartridge can be selected different specifications for use according to actual viscosity and the particle concentration and the size of tested oil product, usually, crosses the optional 2um～20um of specification of filter core, can guarantee to filter the cleanliness factor of back sample substantially.But note that the order number of crossing filter core is close more, the effect of damming that filtrator causes is strong more; When using, should be noted that the relation of actual flow velocity and pressure.In design, filtrator 29 always is mounted in before the dehydrator 30.
9. dehydrator: the free water during dehydrator 30 is exclusively used in out and deoils, guarantee that the moisture in the sample oil is reduced to alap level, guarantee the accuracy of probe measurement.Dehydrator 30 is one of core devices in the pretreatment system.In actual applications, the dehydrator 30 bottoms outlet of releasing.Because dehydrator 30 has adopted coalescence technology, the little water droplet in the sample oil gathers into big water droplet at the outer wall of dehydrator core, and is settled down to dehydrator 30 bottoms under action of gravity, discharges the sampling system of probe by the bleed outlet of bottom.In actual applications, the hand valve 31 of dehydrator 30 belows be opened a very little angle (common 5～10 degree), thereby the coalescent moisture in assurance dehydrator 30 bottoms can be discharged dehydrator 30 at any time.
10. thermostat: temperature is had certain sensitivity because near-infrared analyzer detects, when temperature raises, near infrared spectrum can move to left along wavelength direction, therefore, design has thermostat 34 in the pretreatment system of reality, the oil product that assurance enters probe by constant temperature on a certain fixed temperature, thereby guarantee near-infrared analyzer side amount accurately.The thermostat temperature of suggestion is 30 ℃.Usually the constant temperature means that adopt are constant temperature oil bath.Sample is after entering pretreatment system, at first pass through the cooling of water cooler 26, temperature is reduced to below 30 ℃, through filtrator 29 and dehydrator 30, enter thermostat 34, electric heating unit, temperature sensor, gas cooler are arranged in the thermostat 34, both can heated sample oil, can give the cooling of sample oil to a certain extent again,, guarantee the temperature constant state of sample oil all the time by the temperature control unit of special use.
11. analyte capture jar: the effect of analyte capture jar 19 is manually to grasp sample in system in due course at the scene, uses in order to breadboard analysis.The capacity of analyte capture jar is 1 or 2L, and structure is for bearing the stainless steel component of malleation 0.05Mpa.
12. adjustable rotor flowmeter: adjustable rotor flowmeter 35 is equipped with in the pretreatment system exit below thermostat, can adjust the sample oil body flow velocity in the pretreatment system, the sample oil body flow velocity in the pretreatment system is within the reasonable range.Usually available adjustable rotor flowmeter 35 working ranges are 10～15L/h, and setting range can be 6～8L/h usually, thereby guarantee that the oil body that detects the space by probe has constant compression force and flow, guarantees measurement accuracy.
13. teletransmission tensimeter: the tensimeter of band teletransmission is used in suggestion, and remote transfer signal is sent to the surveillance of DCS, thereby the operator can see the pressure condition of pretreatment system on the DCS of pulpit picture.The pressure condition of pretreatment system is the important operating mode of pretreatment system, and it can reflect directly whether pretreatment system is working properly.If it is working properly, usually the pressure demonstration on the DCS can be a comparatively fixing value (actual size of this value depends on the design of actual sample pretreatment system), undesired if work, then the pressure demonstration on the DCS can be a undesired value, and this value can be a sound and light alarm by configuration, with notifying operation personnel recovery system as early as possible.
14. recycling can: the main effect of recycling can 22 is an outlet waste oil of collecting all pretreatment systems, thereby guarantees not waste oil product, free from environmental pollution.The stainless cylinder of steel that is designed to 2～5m3 (or cylinder of steel of similar volume) of recycling can 22, high low level level switch should be equipped with in inside, thereby when system works, can detect high liquid level and low liquid level in the recycling can, thus indication is reclaimed opening of pump 23 or is stopped.
15. recovery pump: the effect of reclaiming pump 23 is the two position indications according to recycling can, automatically
Turn on pump or close pump automatically makes that the oil body in the recycling can is pumped in the process line, thereby
Make the liquid level in the recycling can be in the safe range all the time.
Sample pretreatment system mentioned above, its design is selected with device, can change to some extent according to the variation of the application site of refinery reality and application places, but mentality of designing substantially is extensively and accurately, can detect for the in-line meter of process industry high-quality preprocessing means is provided.
