A kind of automatic pretreatment system and method for crude oil quick evaluation

Abstract

Provided are a crude oil fast evaluation automatic pretreatment system and method. The system comprises an electric heater, a temperature sensor, a pressure sensor, a controller and a control panel which are arranged on a crude oil evaluation device. The crude oil evaluation device comprises a sample pot used for placing crude oil to be tested and a near infrared analyzer. The electric heater and the temperature sensor are both arranged on the sample pot. The pressure sensor is arranged at the output terminal of the near infrared analyzer. The output terminals of the temperature sensor and the pressure sensor are both connected with a signal input terminal of the controller. The output terminal of the controller is connected with the control signal input terminals of the electric heater and each valve in the crude oil evaluation device. The controller and the control panel are connected bilaterally. The system can achieve automatic heating and flushing of the crude oil evaluation device, is suitable for various crude oil, and is safe and environmentally friendly, convenient and easy to use.

Description

technical field [0001] The present invention relates to a petrochemical product, especially a sample measurement automatic feeding system in a petrochemical product (mainly crude oil) rapid evaluation system, specifically an adaptive feed system for rapid evaluation of crude oil with different viscosities Automatic preprocessing system and method for measurement conditions. Background technique [0002] At present, the crude oil automatic pretreatment system is an important part of the crude oil rapid evaluation system. Crude oil and other petrochemical oils have different properties, viscosities, and pour points. In order to ensure that the sample injection and cleaning requirements are met and provide stable measurement conditions during rapid evaluation, it is necessary to pretreat the tested crude oil samples to make them at a constant Measurements were carried out under conditions of high temperature and high pressure. The current pretreatment of crude oil is mostly p...
