Abstract
The invention discloses a high-efficiency low-temperature oil sludge de-emulsifier, the de-emulsifier comprises the following components by weight part: 4-21 parts of rosin-polythylene oxide ester, 3-18 parts of disodium cocoyl monoethanolamide sulfosuccina, 0.1-1 part of acid catalyst and 60-92 parts of water. A preparation method of the de-emulsifier comprises the following steps: uniformly mixing rosin-polythylene oxide ester, disodium cocoyl monoethanolamide sulfosuccina, an acid catalyst and water, and then obtaining the low-temperature oil sludge de-emulsifier. The oil sludge de-emulsifier has the advantages of good demulsification effect under low temperature, wide usage temperature scope and high oil recovery rate, and the method has the advantages of low production cost, environmental protection, simple process and wide application scope. The oil sludge de-emulsifier can be used for harmlessness treatment of oil sludge at bottom of pot, scummings and activated sludge, and also can be used for treating various kinds of oil-containing sludge generated by petroleum exploitation, storage and transportation enterprises.
