Reasons for high low-methionine content
1. Methanol regeneration failed to meet standards； 2. There are too many impurities in lean methanol ； 3. The system causes methanol contamination of the lean methanol stream due to internal leakage in the valves or other reasons ； 4. High water content in methanol ； 5 The amount of nitrogen used for stripping is insufficient
Pay special attention to the temperature of the lean liquid and the internal components of the tower
If the ammonia level is too high, just open the cryogenic bypass a little
It would be best to provide a detailed explanation of the basic operation of the device and its performance metrics
