Synthesis Operation Procedures 1. When heating the synthesis catalyst, it is necessary to control the rate of pressure and temperature increase, in order to prevent too rapid rises in temperature and pressure from creating excessive pressure differences that could damage the synthesis tower and the internal components of related auxiliary equipment. 2. High temperatures and disassembly or tightening of the synthesis tower components under pressure are strictly prohibited; procedures must be followed to ensure operational safety. 3. When testing for leaks at the thermocouple connections, transformer oil must be used; soap water should never be employed to prevent electrical short circuits caused by alkaline substances. 4. Excessive stability and pressure are strictly prohibited; the temperature of the coal contact layer and the system pressure must be kept within the specified limits. 5. When a new catalyst is used in the synthesis tower, it is essential to strictly follow the procedures for heating and reducing the catalyst. 6. For pressure relief and venting of the synthesis tower, the vent valve at the top of the tower should be opened; if venting is also done at the front of the tower, the pressure there must be higher than that at the back of the tower. 7. Ammonia release should be carried out gradually and frequently to prevent high pressure from escaping to lower pressure levels. It is necessary to closely monitor the pressure and operating conditions of all intermediate liquid ammonia storage tanks to ensure safe production. 8. When discharging oil and water from the oil separator, avoid doing so too forcefully or too quickly. If liquid is found in the refined copper tower, immediate action must be taken to prevent the copper melt from entering the synthesis tower. 9. Strengthen routine inspections; in the event that a sudden increase in pressure in the low-pressure system is detected with no apparent cause, an emergency shutdown should be initiated. 10. The soft water fed into the boiler located after the synthesis tower must be deoxygenated, to ensure that the total solids and C1 content in the boiler water are within the specified limits. 11. Adhere to a strict shift-handover system as well as the rules of “three preparations before starting work, eight prohibitions during duty, and five conditions under which one must not leave work”.
