Abstract

The invention provides a method for processing oil leakage circulation water, which comprises the following steps: a) adding an oxidized bactericide and optional glutaraldehyde; b) adding a scale inhibition corrosion inhibitor, wherein the scale inhibition corrosion inhibitor comprises one or its mixture of water-soluble borate, water-soluble gluconate and water-soluble silicate, at least an organic carboxylic acid polymer, an optional copper material corrosion inhibitor and optional zinc salt; c) adding a long chain alkylaryl sulfonate anionic surfactant; and d) adding a polysorbate non-ionic surfactant. The method of the invention is capable of removing oil of a circulation water system and removing the microbial sludge, the method can be finished at once without discharge of large amount of sludge.

Description

technical field

[0001] The invention relates to a treatment method of circulating water, in particular to a treatment method of oil leakage circulating water. Background technique

[0002] Oil leakage often occurs in the circulating water system, and the oil leaked into the circulating water system generally contains light oil and wax oil. Light oil generally refers to hydrocarbon mixtures with a boiling point range of about 50-350°C. In the petroleum refining industry, it can refer to light distillates or light oil products. The former includes distillates such as gasoline (or naphtha), pyrolysis gasoline, kerosene (or jet fuel), light diesel oil (or atmospheric gas oil), top oil, raffinate, etc., which mainly come from crude oil distillation, catalytic cracking, Thermal cracking, petroleum coking, hydrocracking and catalytic reforming devices; the latter is the oil product obtained after light distillate oil is refined. Wax oil refers to heavy oil containing wax, which ...
