A demulsifier for oil and gas gathering and transportation and its production device

Abstract

A demulsifier for oil and gas collection and transportation and its production device, which relates to a demulsifier. A glass room with an independent air supply and exhaust system is provided in a processing workshop, the production process is controlled by a computer system server and a control switch, and the demulsifier is controlled by a hydraulic jack. (15) Use as much raw material as possible in the raw material barrel A (9) and raw material barrel B (10), and the occupational hazards caused by the worker holding the suction pipe (13) can be avoided due to the lock device; The type I demulsifier and type II demulsifier of the present invention have fast demulsification speed, high dehydration rate and less dosage, which can greatly reduce the interfacial tension of oil-water emulsion and achieve the effect of oil-water separation; the demulsifier production of the present invention The device uses a glass room as a barrier to shield harmful gases, and replaces human hands with controllable trolleys and locking devices. The intelligent control system assisted by a computer system server realizes the monitoring of raw materials.

Description

【Technical field】 [0001] The invention relates to a demulsifier, in particular to a demulsifier for oil and gas gathering and transportation and a production device thereof. 【Background technique】 [0002] With the continuous improvement of crude oil extraction technology and the continuous progress of oilfield exploitation, the average water content of crude oil has reached more than 90%, which has brought great difficulties to the extraction, processing, transportation and other aspects of crude oil. The results of chemical demulsification are obvious and convenient, and chemical demulsification mainly uses surfactants such as demulsifiers, which makes the requirements for demulsifiers more stringent. Crude oil has high water and salt content, and crude oil is rich in various asphaltenes, colloids and other substances, which make the original composition more complicated and greatly increase the difficulty of demulsification. [0003] Emulsion is a very complex dispersion...

AI Technical Summary

Problems solved by technology

With the continuous improvement of the quality requirements of demulsifiers, while the price is as low as possible, the requirements for demulsifiers in terms of environmental protection are becoming more and more stringent. Some conventional demulsifiers can no longer meet the various needs of crude oil production.

At present, the demulsifiers used in China for oil-in-water (O / W) emulsions are not environmentally friendly and are likely to cause irreversible secondary pollution; There are few differences, there is no demulsifier that can handle all types of crude oil production fluids
