Abstract

The invention discloses an oily sludge thermochemical separating agent which is prepared by mixing 0.5-2 parts by weight of diethylamine organic cation molecular film agent, 1-2 parts by weight of dimethylamine organic cation molecular film agent, 0.5-1.5 parts by weight of diisopropylamine organic cation molecular film agent, 0.5-2 parts by weight of butyl amine organic cation molecular film agent and 0.5-1 part by weight of triethylamine organic cation molecular film agent. The oily sludge thermochemical separating agent disclosed by the invention adopts cheap raw materials, is simple to prepare, has stable properties, and can be applied to oily sludge treatment, particularly to treatment of oil tank sediment, and realizes a good oil washing effect, wherein the residual oil rate of the tank oily sediment can be reduced to 0.5% in comparison with the existing separating agent.

Description

technical field [0001] The invention belongs to the technical field of separation, recovery and resource utilization of oily sludge, and in particular relates to a separating agent and a method for separating petroleum from petroleum sludge. Background technique [0002] The main sources of oily sludge are: oil field exploitation, oil and gas gathering and transportation, and sewage treatment plants. Oily sludge is an important pollutant and pollution source, which is very harmful to the environment; if oily sludge is recycled as a resource, it will be an extremely important resource. At present, domestic treatment methods for oily sludge mainly include incineration treatment, solidification treatment, biological treatment, coking treatment, solvent extraction treatment, and reinjection treatment. These methods generally have the disadvantages of long treatment period, high treatment cost and waste of resources. [0003] The chemical heat washing method is an oily sludge tr...
