Coke gas purification technology
After recycling in the chemical industry, coke oven gas retains impurities of sulfur, tar, naphthalene and benzene. When producing electricity from coke oven gas and CCPP, compressing coke oven gas, heating coke oven gas, cutting coke oven gas and producing chemical products from coke oven gas, production problems arise, such as clogging of nozzles, corrosion, excess SO2 emissions after combustion, carbon deposits and poisoning of catalysts, so deep purification of coke oven gas from harmful impurities is necessary.

Coke gas purification technology
Description of technology
After recycling in the chemical industry, coke oven gas retains impurities of sulfur, tar, naphthalene and benzene. When producing electricity from coke oven gas and CCPP, compressing coke oven gas, heating coke oven gas, cutting coke oven gas and producing chemical products from coke oven gas, production problems arise, such as clogging of nozzles, corrosion, excess SO2 emissions after combustion, carbon deposits and poisoning of catalysts, so deep purification of coke oven gas from harmful impurities is necessary.
Due to the high capital investment, complex operation, poor production atmosphere and low removal accuracy of wet desulfurization and naphthalene and benzene oil washing, it is more economical to use the dry fixed bed TSA method.
Our company uses TSA Dry Section Cleaning technology to single-step purify coke oven gas from impurities of H2S, tar, naphthalene, NH3, benzene, HCN, organic sulfides, etc., to obtain suitable purified gas.
Installation scale: 1000~2000000nm³/h.
Specifications
1、Sectional removal of harmful impurities, the adsorbent has a long service life.
2、High precision removal of impurities.
3、Wide use pressure range: 5~3MPa, low power consumption and 10~110% operating flexibility.
4、The resistance difference of the cleaning process is small, generally 2~30kPa.
5、The application of gas recovery technology has completely solved the problems of environmental pollution, wastewater discharge and treatment at the workplace.
6、The machine has a high degree of automation, adaptive control, automatic fault diagnosis and other functions, convenient to start and stop, and can carry out automatic control without human presence.
Applications
Coke oven gas, orchid exhaust gas, artificial gas containing H2S, tar, naphthalene and benzene.
