Example Embodiment

[0009] The present invention will be described in detail below in conjunction with examples.

[0010] Serial number

[0011] The microorganism of the present invention is a mixture of various bacteria that can produce biopolysaccharides, organic acids, alcohols and biosurfactants, mainly including Corynebacterium, Mycobacterium, and Nocardia. The mixture of various bacteria that constitute the microorganisms is produced by Tangshan Jiyou Ruifeng Chemical Co., Ltd. and can be purchased directly.

[0012] The chemical demulsifier is a polyoxyethylene and polyoxypropylene polymer ether with resins as the initiator.

[0013] The inorganic salt contains NH 4 + , Na + , CO 3 2- , Po 4 3- ion.

[0014] The present invention is produced by the following synthetic manufacturing process: add water and inorganic salt to the enamel reaction kettle in proportion, stir to dissolve, and then add quantitative chemical demulsifier in proportion, control the reaction temperature not to...

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...
