Description

technical field [0001] The invention relates to the field of chemical separation, in particular to a separation device for separating wax and colloid from crude oil. Background technique [0002] Crude oil is an important energy source in today's society. Different refined oil products can be obtained through different processing methods. Analyzing the composition of oil, especially the content data of each component in heavy oil can simplify the crude oil extraction and refining process. Therefore , Crude oil composition analysis is of great significance for evaluating the quality of crude oil and making better use of crude oil resources. Heavy components such as waxes and gums in crude oil cannot be determined by simple distillation and rectification methods. In order to determine the content of heavy components such as waxes and gums, it is first necessary to separate the above components from crude oil. At present, the separation of wax and colloid in crude oil is mainl...

Problems solved by technology

However, conventional separation mainly relies on manual operation, which is cumbersome, has poor data repeatability, and low efficiency. In addition, a large amount of toxic and harmful reagents are used in the separation process, which will endanger human health and cause environmental pollution.

In addition, the sample and elution solvent use the same injection channel, which will cause cross-contamination, affect the accuracy of the results, and waste a lot of time cleaning the injection channel

With the increase of exploration scale, the detection period of each sample is 5 days, which seriously restricts the efficiency of crude oil property evaluation
