It is to remove the large amounts of gaseous light oils, ammonia, water, hydrogen cyanide, unsaturated hydrocarbons, and high-boiling-point impurities present in the raw gas, so as to prevent them from entering the main washing section and causing methanol contamination, which could affect absorption and regeneration processes
Removes impurities such as gaseous naphtha and high-boiling hydrocarbons from gas.
Removes impurities such as gaseous naphtha and high-boiling hydrocarbons from gas.
The purpose of pre-washing is to lower the freezing point of water in the feed gas.
Removes impurities such as gaseous naphtha and high-boiling hydrocarbons from gas.
Removal of impurities such as gaseous naphtha and high-boiling hydrocarbons from gas
Removes impurities such as gaseous naphtha and high-boiling hydrocarbons from gas.
The large amounts of gaseous light oils, ammonia, water, hydrogen cyanide, unsaturated hydrocarbons, and high-boiling-point impurities (naphtha) present in the raw gas are removed to prevent them from entering the main washing section and causing methanol contamination, which could affect absorption and regeneration processes.
