The purpose of removing acidic gases from the pyrolysis gas is to prevent contamination and corrosion in the systems downstream
In addition to dealing with acidic gases, the aim is to prevent the formation of dry ice that could block pipes, to avoid equipment corrosion, to prevent catalyst poisoning, and to ensure product quality
The purpose of removing acidic gases from pyrolysis gas is to purify the pyrolysis gas.
The purpose of removing acidic gases from the pyrolysis gas is to prevent the formation of dry ice that could block pipelines, to avoid equipment corrosion, to prevent catalyst poisoning, to purify the pyrolysis gas, and to ensure product quality. The impurities that need to be strictly controlled in the pyrolysis gas include acidic gases such as H2S, CO2, H2O, C2H2, and CO. These impurities are not in large quantities, but they are harmful to the cryogenic separation process and can cause the product to fail to meet the specified standards. So it must be removed.
The removal of acidic gases from pyrolysis gas is generally necessary for product purification, and it is also needed to protect the process equipment. In the oil refining industry, desulfurization and denitrification are carried out through measures such as washing, alkaline washing, and stripping after the compression stage, while in the ethylene industry, washing and alkaline washing are performed before compression
