Problems solved by technology

[0006] The purpose of the present invention is to overcome the weaknesses of the prior art in solving the oil leakage of the circulating water system, such as the large waste of water resources, the large concentration of medicament dosage and the incomplete cleaning, and the shortcomings of the prior art in solving the oil leakage of the circulating water system Most of the methods are operated at low concentration multiples. First, a large amount of fresh water is wasted. Second, oily substances will remain in the circulating water system, which will bring defects such as corrosion and heat transfer to the circulating water system and the surface of the heat exchanger.

Abstract

The invention discloses a greasy sludge cleaner composition and a method of use thereof, wherein, the composition contains D-limonene and polyethylene glycol, and the weight ratio of the D-limonene to the polyethylene glycol is 1: 0.25-1.5. The oil sludge cleaning agent composition of the present invention is applied in the circulating water system of oil leakage, which has good cleaning effect, low cost, and less dosage. After cleaning, hydrogen peroxide aqueous solution is added to accelerate the degradation of the cleaned oily substances. Avoid secondary pollution, and reduce the corrosion and scaling problems caused by oil leakage to the circulating water system without reducing the concentration multiple of the circulating water system, which has high economic and social benefits.

Description

technical field [0001] The invention relates to an oil sludge cleaning agent composition for circulating water and an application method thereof. Background technique [0002] Water resources have become an important factor restricting the development of petrochemical enterprises, and water saving work is urgent. The circulating water system is a large water user. At present, increasing the concentration ratio is the most direct and effective water-saving method for circulating water. However, if the circulating water system leaks material, it needs to be replaced with a large amount of fresh water, which not only wastes a large amount of fresh water, but also greatly increases the consumption of water treatment chemicals, and greatly increases the cost. [0003] Oil leakage is a common occurrence in the circulating water system of petrochemical enterprises. The manifestations of oil leakage in circulating water are: first, the oil content of the system increases, and seco...
