Technology comment
The production process of this product includes: (1) gasification of coal powder to produce raw synthetic gas, which undergoes sulfur-resistant shift conversion via Co-Mo catalysis, followed by cold methanol washing for sulfur recovery with liquid sulfur as a by-product. (2) Purified synthetic gas is converted into methanol using a Lurgi low-pressure methanol synthesis unit, methanol distillation columns, and hydrogen recovery units; methanol is then separated into olefins via MTO process, and olefins are cracked to produce ethylene. (3) Ethylene is oxidized to produce ethylene oxide, which is subsequently hydrated to form ethylene glycol.
