摘要
Disclosed are a purification assistant for coal chemical industry production and uses thereof in the coal chemical industry production. The purification assistant for coal chemical industry production comprises 90 to 99 parts of N-Polyoxyethylated-N-oleylamine and 1 to 5 parts of fatty amine in parts by weight. The purification assistant has the following effects: 1) the content of suspended solids in ammonia water and phenol water is greatly reduced, so that separation effects of coal tar and coal cinder in ammonia water and phenol water are good, and accordingly, the loss of coal tar is reduced and the yield of the coal tar is increased; 2) the water content in the coal tar is reduced; 3) a large quantity of sediments such as oil slag in each tank body and an evaporator tank heat-exchanging system are greatly cleaned, so that the blockage phenomenon is avoided, the system cleaning frequency is reduced, and the service life of a device is extended; and 4) the COD and phenol content in gasification wastewater are reduced, and raw coke oven gas is cleaned. Therefore, the purification assistant provided in the present invention is a high-efficiency product capable of reducing the viscosity of coal tar and reducing water content of an oil product.
