Coal chemical industry refers to the process of converting coal into gas, liquid, and solid fuels and chemicals through chemical processing. It mainly includes coal gasification, liquefaction, dry distillation, tar processing, and calcium carbide acetylene processing. Coal chemical processing. The chemical structure of organic matters in coal takes the condensed nucleus of aromatic (mostly) as a unit core, which is of bridged linkage and has a macromolecular structure with various functional groups. Through thermal and catalytic processing, coal can be converted into various kinds of fuels and chemical products.
II. Coal tar industry
Coal tar is a dark brown viscous liquid produced during the dry distillation of coal, referred to as tar; the black brown produced during the coal dry distillation is related to a viscous liquid reeking of a pungent odor, with a yield accounting for about 3~4% of the dry coal;
The crude tar is recovered from the coal gas produced in the coking process that is sprinkled with circulating ammonia and condensed in a primary cooler. It contains large water, about 4%, sometimes 8~10%;
* Technical characteristics of three-phase centrifuge for coal tar
The heavy liquid phase separated by the centrifuge can adopt two different liquid discharging modes. 1.High-performance sealing structure can effectively reduce the overflow of irritating gas, improve the air quality at the operation site, and reduce environmental pollution; 2.High-performance sealing material can effectively avoid the swelling failure of ordinary rubber parts; 3.The coke button in the coal tar is an important factor affecting the stability and service life of the centrifuge due to abrasion.
[ZK Separation] centrifuge is equipped with high-performance wear-resistant protective materials, greatly prolonging the maintenance cycle and ensuring the annual normal running time.
* Separation performance (typical medium and high temperature coal tar) of coal tar three-phase centrifuge: The centrifuge features high separation efficiency, compact structure, and continuous operation. The diameter of the separated particles can be reduced to 2 μm. 1. The solid content (toluene insoluble matter) in the treated coke button is more than 45%, which can easily optimize the clarification of liquid and the dryness of solids. 2. Tar quality after separation: aqueous ammonia content: <2.5%; tar content: ≥97%; solid content (> 100 μm): <0.3% 3. After separation, the tar in the aqueous ammonia: ≤ 4g/L
