Problems solved by technology

At present, physical and chemical methods are usually used to treat petrochemical waste at home and abroad. Due to the complex composition of petrochemical waste and the soil has certain adsorption properties, it is difficult to remove oil, water, and sediment by ordinary chemical and physical methods. and impurities are completely separated, and the treatment effect is poor; in addition, secondary pollution is likely to occur during the treatment process, which cannot completely solve the problems of comprehensive utilization of resources and environmental pollution

Abstract

The invention discloses a petrochemical engineering waste separating processing method. The petrochemical engineering waste separating processing method comprises the following steps of: adding petrochemical engineering waste and water into a processor based on a weight ratio of 1: 0.5 to 1.5; heating to reach 60 to 95 DEG C; adding 0.3 to 1.2% of cracking agent to the processor based on weight of the petrochemical engineering waste; fully agitating to obtain oil, the water and impurity; and standing and precipitating so as to completely separate the oil, the water and the impurity. With the adoption of the petrochemical engineering waste separating processing method disclosed by the invention, so that the petrochemical engineering waste can be effectively processed, impurities such as sand and stones, soil, metal filing and surface active agents can be completely separated from the oil; the oil can be recycled, wastewater can be recycled, and processed impurity can be used as fuel, waterproof materials, snow melting agents, cement additives or buried after reaching a standard, therefore, harmless resource comprehensive utilization of the petrochemical engineering waste can be achieved, a good processing effect can be achieved, a short processing period can be ensured, no secondary pollution occurred in a processing procedure, and processing is carried out with low cost.

Description

technical field [0001] The invention belongs to the technical field of petrochemical waste treatment, in particular to a method for separating and treating oily petrochemical waste. Background technique [0002] In the process of petrochemical production, a large amount of acid residue, waste engine oil, oily alkaline water, oily white clay, coal tar residue in coking plants, shale oil residue, oil sand slag, oil field and refinery sludge, etc. waste. The above-mentioned petrochemical wastes are directly discharged without treatment, which will not only cause waste of resources, but also pollute the environment. At the same time, petrochemical enterprises also need to pay a huge amount of pollution compensation fees, which greatly increases the operating costs of enterprises. However, the treatment of petrochemical oily wastes has always been a problem that has plagued the petrochemical industry, and this problem is also a key topic of concern to governments and enterprises...
