Abstract

The invention relates to a delay coking coke cooling water demulsifier composition and a preparation method and application thereof. The demulsifier composition comprises the following components in percentage by mass: 1 to 25 percent of demulsifier, 1 to 20 percent of dispersing agent, 1 to 25 percent of penetrating agent, 1 to 20 percent of corrosion inhibitor and the balance of solvent. The invention also provides the preparation method for the demulsifier composition and the application of the demulsifier composition to a delay coking device. The demulsifier composition mainly contains the demulsifier, the dispersing agent, the penetrating agent, the corrosion inhibitor and the solvent. By the demulsifier composition, the coke cooling water can be demulsified quickly, and the oil content of water can be reduced obviously; a water body is clear after demulsification; the corrosion of the water body to equipment can be reduced; and meanwhile, the demulsifier composition does not contain any inorganic ion, so that the influence on the conventional water body system is avoided.

Description

technical field

[0001] The invention belongs to the technical field of industrial sewage treatment, relates to a chemical auxiliary demulsifier, in particular to a demulsifier composition applied to oily sewage produced by decoking a delayed coking coke tower, and a preparation method and application thereof. Background technique

[0002] Delayed coking is the process of converting residual oil into gas, light and middle distillate oil and coke through deep thermal cracking. It is the main means for refineries to increase the yield of light oil and produce petroleum coke.

[0003] The removal of coke adopts hydraulic decoking technology. During the cooling and removal process of coke, dust, sewage, waste gas and other pollutants will inevitably be generated, which will seriously affect the device and the surrounding environment, especially in the case of large water supply cooling coke, soaking coke, During the overflow process, a large amount of oily and sulfurous sewage wi...
