Problems solved by technology

[0003] The pre-treatment of oil-water-solid three-phase colloidal form of polymer-containing sludge dehydration, the system remains stable for a long time, the dehydration reduction is difficult, the deoiling is difficult, there is a lack of effective destabilizing agents, and there is no supporting corresponding reduction treatment process
At present, it can only be used as fuel additives or washed with water after simple treatment such as pressure filtration. Not only the degree of resource utilization is very low, but also the transportation cost is high, which is not a small burden for enterprises.

Abstract

The invention discloses compound treatment agents for oily sludge containing polymers and a usage method thereof, and belongs to the technical field of polymer-containing oily sludge treatment in petroleum oilfield. The compound treatment agents for the oily sludge containing the polymers comprise an agent A, an agent B, an agent C and an agent D; the agent A is composed of sodium carbonate, sodium silicate and sodium hydroxide; the agent B is composed of an OP emulsifier, Peregal, Triton X-100 and sodium dodecyl benzene sulfonate; the agent C is composed of sodium hypochlorite and hydrogen peroxide; and the agent D is composed of aluminum sulfate, sodium sulfate and polyferric sulfate. The usage method of the compound treatment agents for the oily sludge containing the polymers comprisesthe following steps: a, putting oily sludge containing polymers into a reaction kettle, adding water, and carrying out heating with stirring; b, adding the agent A and carrying out uniform stirring, adding the agent B and carrying out uniform stirring, adding the agent C and carrying out uniform stirring, and adding the agent D and carrying out uniform stirring; and c, performing standing-precipitating on the mixture of the oily sludge and the water, and separately retrieving oil, sludge and water after stratification. The compound treatment agents for the oily sludge containing the polymers and the usage method thereof are capable of realizing effective separation on the three phases of oil, sludge and water in the oily sludge containing the polymers so as to achieve reduction and resource recycling; and thus, the problem of performing harmless treatment and resource recycling on hazardous solid waste from oilfield is effectively solved.

Description

technical field [0001] The invention relates to the technical field of oilfield oil sludge treatment, in particular to a polymer-containing oil sludge compound treatment agent and a use method thereof. Background technique [0002] Due to the rapid development of the world economy, the demand for oil is increasing day by day, the scale of oil field exploration is expanding, and the refinery is also expanding and increasing the load. In the process of oil exploration, mining, refining, tank cleaning, storage and transportation, due to accidents, leakage, natural settlement and other reasons, a large amount of crude oil or oil products and soil, water or other impurities form oily sludge or sewage. Among them, polymer-containing oil sludge is solid waste produced in the process of oilfield exploration and development. Its main characteristics are high water content, complex composition, and various toxic and harmful substances such as polymers, oils, benzene series, and phenol...
