Abstract

A composite ionic fluorinated alkyl benzene sulfonate oil-sand separation agent and a preparation method and application thereof. The separation agent comprises the following components: 0.3%-0.5% of perfluorinated phosphate, 10%-15% of alkylbenzenesulfonate, 10%-15% of sodium alcohol ether sulphate, 5%-10% of ethylene glycol, 3%-5% of sodium silicate, 3%-5% of sodium phosphate, 3%-5% of sodium chloride salt and the balance of water. The oil-sand separation agent is applicable to chemical formula for cleaning polluted oil and sludge floor, and separating crude oil and sediment, has wide temperature range, and can successfully separate polluted oil and sediment at the temperature above the freezing point of crude oil. After several experiments, the oil in mud is less than 2%, which is up to the national standard. The separation agent saves energy, reduced pollution, and greatly improves the ecological environment.

Description

technical field [0001] The invention relates to an oil-sand separating agent and a method for cleaning dirty oil sludge by using the oil-sand separating agent, which can be widely used in environmental protection engineering in oil field production. Background technique [0002] At present, the national oilfields produce about 5 million tons of sludge annually, and the methods used are deep burial, incineration, and chemical cleaning. Due to the limitation of technical conditions, it will affect the ecological environment. The existing products include heavy alkylbenzene sulfonate or petroleum sulfonate, and the oil washing rate is low {oil washing rate 30%}. Contents of the invention [0003] The technical solution of the present invention is to overcome the deficiencies of the prior art, and provide a composite ion fluorinated alkylbenzene sulfonate oil-sand separator and its preparation method and application, which save energy and protect the environment, reduce pollu...
