    Abstract：Due to low calorific value, released gas produced from domestic refineries is not suitable for fuel gas and led directly into flare system and vented to air after burning. If such released gas is recycled, it can be avoided to result in resource waste and environmental pollution. Conducted is analysis on such issues as difficult recovery of released gas from refinery and unreasonable feed gases ratio of methanol unit, improved is the recovery process of released gas and applied is the new process “Low Pressure Gathering and Gradual Pressurization” so as to meet requirements of released gas recovery and substantial decrease of equipment investment. As one of feed gases of methanol unit, recovered released gas can make feed gases reach suitable hydrogen carbon ratio, accordingly, consumption of natural gas can be decreased, methanol output can be increased and C02 emissions can be decreased obviously, which has obvious effect in energy conservation and emissions reduction.
