Recently, Shandong Laigang Coking Plant's refined benzene workshop smoothly achieved the outflow of acid tar, which made the burden of headaches over the past 20 years turned into wealth, avoided secondary pollution of the environment, and created direct economic benefits of 20,000 yuan per year.
Laigang Coking Plant Refined Benzene Plant Light benzene refining adopts pickling process, producing 6 tons of waste acid tar per day. Because it belongs to serious pollutants, it can not be discharged, and there is no acid tar processing device. It has been put into coal preparation workshop since 1987. The pulverized coal is coke-making. Due to the mixing of acid tar and coal, toxic substances such as sulphuric acid and benzene hydrocarbons evaporate, causing air pollution and adversely affecting the health of the employees. At the same time, the acid tar corrodes the equipment more severely, greatly increasing maintenance costs and employee labor. strength. To this end, the plant has organized relevant departments to jointly administer acid tar. After chemical analysis, they found that acid tar contains acidic polymers such as sulfuric acid and has high recycling value. The plant has been actively looking for acid tar processing factories nationwide and has been carrying out equipment modification at customer's request. After the acid tar came out, it not only successfully sold new products, but also extended the service life of equipment such as coal preparation, and also avoided environmental pollution.
