It is to remove the large amounts of gaseous light oils, ammonia, water, hydrogen cyanide, unsaturated hydrocarbons, and high-boiling-point impurities (naphtha) present in the raw gas, so as to prevent them from entering the main treatment stage and causing methanol contamination, which could affect absorption and regeneration processes

Removes impurities such as gaseous naphtha and high-boiling hydrocarbons, ammonia, water, etc., from gas.
1. Set up a pre-washing section to remove impurities such as NH3 and HCN from the feed gas. 2. Pre-washing and regeneration (extraction and distillation): Remove naphtha and other substances carried in the feed gas, thereby regenerating methanol and recovering it, to obtain naphtha product.
