Method for preparing improved water washing treating agent

Abstract

The invention discloses a method for preparing an improved water washing treating agent. The method comprises the following steps: 1) adding 5wt%-10wt% of sodium dodecyl benzene sulfonate into an enamel reaction still, and starting a stirrer for continuously stirring sodium dodecyl benzene sulfonate at the temperature of (50+ / -1) DEG C when the temperature inside the enamel reaction still is controlled to be (50+ / -1) DEG C all the time; 2) adding 82(wt%-85wt% of water into the enamel reaction still, and continuously stirring sodium dodecyl benzene sulfonate and water which are added into the enamel reaction still for 10 min for uniform mixing through the stirrer; 3) gradually adding 1wt% of polysorbate into the enamel reaction still, and continuously stirring sodium dodecyl benzene sulfonate, water with polysorbate which are added into the enamel reaction for 10 min for uniform mixing through the stirrer; 4) sequentially adding 2wt%-8wt% of sodium hydroxide and 1wt%-5wt% of sodium carbonate into the enamel reaction still, and continuously stirring sodium dodecyl benzene sulfonate, water, polysorbate, sodium hydroxide and sodium carbonate which are added into the enamel reaction for 5 min for uniform mixing through the stirrer, so as to synthesize the improved water washing treating agent. The method is easy, feasible, and low in implementation cost.

Description

technical field [0001] The invention relates to a synthesis process of an oil field waste treatment formula, in particular to a method for preparing an improved water washing treatment agent. Background technique [0002] Oily sludge is oily solid waste produced during oil extraction, transportation, refining and oily sewage treatment. With the in-depth development of oil recovery technology in oil fields, the water content in the produced oil is getting higher and higher, especially in the development process of heavy oil, the formation production fluid also carries mud and sand, in the crude oil dehydration process and subsequent sewage treatment process A large amount of oily sludge will be produced. Oily sludge includes tank cleaning sludge, landing sludge and scum bottom sludge. The treatment is difficult, the one-time investment of the treatment equipment is high, and the economic benefit is poor. If the oily sludge is not treated, it will not only pollute the environ...

AI Technical Summary

Problems solved by technology

Thermochemical treatment process and mechanical water washing separation process are the current research hotspots in the oily sludge treatment process. These two processes have high requirements for the treatment of water washing agents, otherwise the oily sludge treatment effect is poor

[0003] To sum up, the existing domestic and foreign processes for treating oily sludge are relatively complicated and costly to implement.
