De-emulsifiers for oil and gas gathering and transferring and production device thereof

Abstract

The invention discloses de-emulsifiers for oil and gas gathering and transferring and a production device thereof, and relates to a de-emulsifier. In a processing workshop, a glass house provided withan independent ventilation system is arranged; and the production process is controlled by a computer system server and a control switch. Through a hydraulic jack (15), raw materials in a raw material barrel A (9) and a raw material barrel B (10) can be maximally utilized. Due to an opening locker, the damage to the health of a worker who holds a suction pipe (13) is avoided. The provided I typede-emulsifier and II type de-emulsifier have the advantages of quick demulsifying speed, high dehydration rate, and little using amount, can maximally reduce the interfacial tension of water-oil emulsion, and separate water and oil. The glass house is used to barrier harmful gas. A controllable plate trailer and the opening locker are used to replace manual operation. An intelligent control systemformed by the computer system server is used to monitor raw materials.

Description

[0001] 【Technical field】 [0002] The invention relates to a demulsifier, in particular to a demulsifier for oil and gas gathering and transportation and a production device thereof. [0003] 【Background technique】 [0004] 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. [0005] Emulsion is a very com...

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
