COG purification

After the chemical recovery of coke oven gas still exists in the sulfur, tar, naphthalene and benzene and other impurities on the coke oven gas power generation, CCPP power generation, coke oven gas compression, coke oven heating, coke oven gas cutting and coke oven gas chemical products and other processes, such as clogging of the nozzle, corrosion, combustion SO2 emissions exceeded the standard, carbon build-up and poisoning of catalysts, and other production problems, so the need for deep decontamination of the harmful impurities in the coke oven gas. Therefore, it is necessary to deeply remove harmful impurities from coke oven gas.

Hydrogen from coal gasification

Hydrogen from raw coke-oven gas

Barren coal gas is characterised by large gas volume, low pressure, complex impurity content and low hydrogen content. In addition to being utilised as power generation, hydrogen can be extracted and used as feedstock gas for chemical products such as coal tar hydrogenation, ethylene glycol and synthetic ammonia.
