Abstract
The invention relates to a de-emulsifier high-temperature static selection device, which is mainly composed of an oil bath pan, a temperature control instrument, a taper trial jar frame, and an oscillator. According to the invention, when the thermochemical settlement selection of the heavy inferior crude oil de-emulsifier is carried out under high-temperature oil bath condition, the used oil bath pan and the taper trial jar frame are processed by employing transparent, corrosion-resistant, high temperature-resistant and overpressure-resistant materials, wherein the taper trial jars employs double sealing, a segment of planoconvex lens is employed between 0-20 ml scales at the bottom of the taper trial jars, so that the scale and phenomenon when oil and water are separated can be conveniently observed and recorded. when the selection of a heavy inferior crude oil high-temperature static demulsification thermal chemical agent, the testing temperature is determined according to basic property of the crude oil by referring the temperature, density curve and viscosity-temperature curve graphs of the crude oil, the oil constant temperature of the transparent oil bath pan is set through the temperature control instrument, when the temperature of the transparent oil bath pan displays a set temperature, the thermochemical settlement selection test of the crude oil de-emulsifier is carried out by the device according to a usage performance detection method of the crude oil de-emulsifier.
Description
Technical field
The invention belongs to crude oil demulsifier heat chemistry competition technical field, particularly to a kind of demulsifier high temperature static competition dress
Put.
Background technology
Crude oil electric desalting, electric dehydration are the pretreatment process that oil field is important together with in refinery's oil refining process flow process.Desalination journey
The quality of degree directly influences crude oil following process device, in particular for carrying out the refinery of crude oil deep processing to de-rear crude oil
There are strict requirements: salt content≤3mg/l, water content≤0.3%.For reaching this requirement of oil refining process, add and be suitable for
Crude oil demulsifier be widely used in technology of electric de-salting running.Classification and kind due to crude oil demulsifier
Various, it is proposed an industry standard for crude oil demulsifier applicable performance detection method China National Petroleum industry: former
Oil demulsifier serviceability detection method, SY/T5281-2000.By using the demulsifier serviceability of this standard formulation
Detection method, it is possible to realize the transconversion into heat for different crude oils of the different classes of demulsifier product under the conditions of room temperature～100 DEG C
Settling property is chosen, thus chooses and have demulsifier product targetedly, and i.e. different oil products are selected to its specific aim relatively
Strong demulsifier product.
But be as domestic oil extraction, the biggest change that refinery's processing crude quality produces, by lightweight in early days, excellent
Matter crude oil has gradually become heavy, viscous crude inferior.Oil property has a very large change, be mainly manifested in density relatively big,
Viscosity is higher.Use crude oil demulsifier serviceability detection method for the heavy occurred at present, viscous crude inferior, at room temperature～
Under the conditions of 100 DEG C, it is carried out the competition of different classes of demulsifier heat chemistry settling performance, the performance effect of different classes of demulsifier
Really difference is little, or perhaps can not show the real property of different classes of demulsifier at the cryogenic conditions of room temperature～100 DEG C
Energy.It is primarily present and has a problem in that heavy, thick oil viscosity inferior are relatively big, room temperature～the cryogenic conditions impact of 100 DEG C
Water droplet in heat chemistry Selection Method assembles sedimentation velocity, it is impossible to accurately counterweight crude oil with poor quality carries out demulsifier heat chemistry and sinks
Fall performance competition, it is impossible to choose preferable crude oil demulsifier, even there will be negative effect, go out in causing electrical desalter
Existing emulsion, there is large effect in stable operation and technical specification to electrical oil dewatering salt system.
Summary of the invention
It is an object of the invention to be to provide a kind of demulsifier high temperature static competition device, natural to solve existing CNPC
Gas industry standard: crude oil demulsifier serviceability detection method can not realize asking of hot conditions demulsifier serviceability detection
Topic such that it is able to realize counterweight crude oil with poor quality and carry out crude oil demulsifier serviceability detection.
The technical scheme is that a kind of demulsifier high temperature static competition device mainly by oil bath pan, temperature controller,
Taper trial jar, taper trial jar frame, agitator etc. form.When carrying out weight crude oil with poor quality demulsifier serviceability detection, according to
Crude oil fundamental property, with reference to temperature-density curve and the viscosity-temperature curve figure of crude oil, determines test temperature, by temperature control
Instrument processed arranges clean oil bath oil steady temperature, until clean oil bath temperature show reach design temperature time, according to crude oil break
Emulsion serviceability detection method carries out the competition test of crude oil demulsifier heat chemistry settling.In order to it is bad to observe weight intuitively
Matter crude oil carries out demulsifier heat chemistry settling competition under the conditions of high temperature oil bath, and oil bath pan, taper trial jar that test uses are equal
Material transparent, corrosion-resistant, high temperature resistant, pressure is used to process.Wherein taper trial jar uses two resealings: one is to adopt
The bottle stopper having twice annular O with inside seals；Two is to design screw thread in the outside of bottle stopper lid, and makes and one
Supporting bottom, passed by bottom taper trial jar, press examination bottle mouth wall tighten with bottle stopper spiral.Meanwhile, try in taper
Use one section of planoconvex lens bottom Ping between 0-20ml scale, facilitate scale and phenomenon that observed and recorded oil-water separation is.
The invention has the beneficial effects as follows: a kind of demulsifier high temperature static competition device of the present invention, it is achieved that counterweight poor quality is former
Oil carries out the demulsifier performance detection of hot conditions so that static demulsifier heat chemistry chooses reality of more fitting, and is broken
The commercial Application of Emulsion provides more reliable laboratory facilities.
