Key points for normal operation of the alcohol unit: Answer: 1. Control of bed temperature; based on changes in the CO content in the conversion gas as well as the volume of gas flow, it is necessary to adjust promptly the opening degrees of the internal bypass valves, the auxiliary line valves, and the bypass valves of the circulation pump. In special situations, the main valve of the electric furnace can be activated to control the temperature and ensure that it remains within the specified range. 2. Control of CO content in the gas after alcohol separation; depending on the gas flow rate and changes in the CO content at the inlet, it is essential to adjust the load on each tower appropriately, operate the circulation pump properly, and keep the temperature at normal levels to ensure that the CO content in the outlet is less than 1.0%. The temperature parameters should also be adjusted accordingly based on the load in the copper washing section. 3. Prevention of gas carrying alcohol and leakage of alcohol-containing gas; it is important to strengthen the process of alcohol separation. The liquid level in the alcohol separation tank should not be set too high to prevent gas from carrying alcohol, nor too low to avoid large amounts of alcohol-containing gas from entering the storage tank
