Problems solved by technology

[0002] Dehydration of crude oil has always been a major problem that plagues the development of the petroleum industry. The dehydration temperature is high, the dosage of chemicals is large, and the overall cost of dehydration is high.
Due to the high dehydration temperature, the energy consumption is greatly increased, and the dosage of chemicals is large. On the one hand, it increases the difficulty of subsequent treatment of oil products. On the other hand, the use of too many chemicals is not conducive to environmental protection.
In the past ten years, the research on microbial demulsifiers at home and abroad is only indoor research, and its shortcomings are: high development cost, slow dehydration speed, and unsatisfactory dehydration effect

Abstract

The microbial emulsion breaker is composed of (wt%) 10-25% of microbe, 25-50% of chemical demulsifier, 0.1-5% of inorganic salt and 25-50% of water. The utilization of said invented product can greatly reduce oil and water interfacial tension, and has the advantages of quick dewatering speed, lower dewatering temp. and low oil content in discharged sewage.

Description

technical field [0001] The invention relates to a chemical auxiliary agent for oil field gathering and transportation, in particular to a microbial demulsifier used for dehydration of paraffin-based crude oil and asphalt-based crude oil. Background technique [0002] Dehydration of crude oil has always been a major problem that plagues the development of the petroleum industry. The dehydration temperature is high, the dosage of chemicals is large, and the overall cost of dehydration is high. Due to the high dehydration temperature, the energy consumption is greatly increased, and the dosage of chemicals is large. On the one hand, it increases the difficulty of subsequent treatment of oil products. On the other hand, the use of too many chemicals is not conducive to environmental protection. In the past ten years, the research on microbial demulsifiers at home and abroad is only indoor research, and its shortcomings are: high development cost, slow dehydration speed, and unsa...
