The paper analyzes and investigates methanol purge gas producing in 200 000 t/a coke oven gas to methanol process, it proposes recycling method in producing LNG by methanol purge gas, it obtains that producing LNG by methanol purge gas is the most effective and most economical way after contracting recycling methods between synthesis ammonia and synthesis methanol by methanol purge gas. After the implementation of the project, the company can produce LNG 13 400 t/a, 22 million yuan profit.
