(5 points) Answer: The important factors affecting the ethylene yield in the demethanization tower are: operating temperature, pressure, and methane/hydrogen ratio. Correct: +5, Explanation: +10, Sharing experience: +20. Other moderators of this version, please assist with scoring
The main factors affecting the ethylene yield in the demethanization tower include the methane/hydrogen ratio, operating temperature, and operating pressure. The higher the methane/hydrogen ratio, the less ethylene is lost in the overhead gas, and the higher the ethylene yield ； Conversely, the higher the hydrogen content in the pyrolysis gas, the lower the methane/hydrogen ratio. To meet the requirements for the tower top dew point, more ethylene and ethane must be lost, which results in a decrease in the ethylene yield.

Feed composition, operating pressure, and operating temperature are important factors affecting the ethylene yield in the demethanization tower.
The main factors affecting the ethylene yield in the demethanization tower include operating temperature, operating pressure, and the methane to hydrogen ratio in the feed.

Methane/hydrogen ratio, operating temperature, and operating pressure
These include the methane/hydrogen ratio, operating temperature, and operating pressure. The higher the methane/hydrogen ratio, the less ethylene is lost in the overhead gas, and the higher the ethylene yield ； Conversely, the higher the hydrogen content in the pyrolysis gas, the lower the methane/hydrogen ratio.
