Abstract

The invention relates to a separating agent and method for separating petroleum from petroleum sludge. The separating agent is prepared by mixing 0.5-2 parts by mass of a diethylamine organic cationicmolecular film agent, 1-2 parts by mass of a dimethylamine organic cationic molecular film agent, 0.5-1.5 parts by mass of a diisopropylamine organic cationic molecular film agent, 0.5-2 parts by mass of a dibutylamine organic cationic molecular film agent, and 0.5-1 part by mass of a triethylamine organic cationic molecular film agent. The thermochemical separating agent for oily sludge preparedby the method is cheap in raw materials, easy in preparation method, stable in properties and good in oil washing effect, and can be used for treating oily sludge, specially oil tank bottom sludge. Compared with a conventional separating agent, a residual oil rate of the tank bottom oily sludge can be reduced to 0.5% at the minimum.

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...
