Dynamic test device of volatilization of crude oil

Abstract

The embodiment of the invention provides a dynamic test device of the volatilization of crude oil. The volatilization test device of volatile matters in crude oil comprises a tank unit, a power unit, a electromechanical control unit and a test data acquisition unit, wherein the tank unit is used to hold crude oil; the power unit is connected with the tank unit and used to provide circulating thrust and pull through an electrohydraulic push rod and drive the tank unit to perform reciprocating motion; the electromechanical control unit is connected with the power unit and used to control the power unit to provide periodic thrust and pull for the tank unit; the test data acquisition unit is connected with the tank unit and used to collect and store the test data of the tank unit; the test data acquisition unit contains a sensor arranged on the tank unit; and the sensor is used to monitor the volatile matters volatilized from crude oil in the tank unit and obtain the test data. By using the test device of the invention, the long-distance transportation simulation test of volatile matters in crude oil can be realized through temperature control and vibration working condition control.

Description

technical field [0001] The invention relates to the technical field of petroleum, in particular to a dynamic test device for volatilization of crude oil. Background technique [0002] Sour crude oil contains a certain amount of volatile combustible gas such as a small amount of H 2 S gas, etc., once these volatile substances volatilize and enter the atmosphere during crude oil transportation, it may cause casualties, environmental pollution, and lead to a decline in the quality of crude oil. At present, railways and roads are one of the important modes of crude oil transportation, and they are also one of the transportation modes with the greatest possibility of volatile leakage of crude oil. Therefore, volatile and combustible gases such as H 2 The research on the volatilization law of S gas and its influencing factors is of great practical significance. [0003] Most of the crude oil produced in some oilfields discovered in China in recent years is sulfur-containing crud...

AI Technical Summary

Problems solved by technology

At home and abroad, only the volatilization characteristics of substances such as water and refined oil are studied, and most of them adopt natural evaporation test methods, which cannot realize the research on the volatilization characteristics of sulfur-containing crude oil under the influence of dual factors of vibration conditions and temperature changes

It can be seen that up to now, there is no long-distance transportation simulation test device for volatile substances in crude oil that can realize temperature control and vibration condition adjustment.
