Scope

Main Technical Content: 2.1 Preparations Before Startup 2.1.1 Prepare protective gear and emergency rescue supplies. Duty personnel must wear labor protective gear. 2.1.2 Check whether the power supply to all pump areas is in place and whether the motor wiring is correct. 2.1.3 Start the cooling water pump, gradually open the supply and drain valves of all equipment using cooling water, and control the cooling water pressure to no more than 0.3MPa to avoid damaging cooling equipment. Observe whether the cooling water pipelines are unobstructed. 2.1.4 Check whether all pipelines, equipment, and valves of the distillation system are in a safe standby state. 2.1.5 Notify the steam supply and chlorine supply stations to supply steam and chlorine. Check the chlorine and steam pipelines and valves to ensure no leaks. 2.2 Startup Operation 2.2.1 Open the hydrobromic acid pump inlet valve. After the hydrobromic acid fills the pump body, start the hydrobromic acid pump and gradually open the pump outlet valve. Control the feed rate of hydrobromic acid to the distillation tower at about 1m3/h. Open the hydrobromic acid valve at the bottom of the tower and close the waste acid valve, forming a closed loop between the hydrobromic acid pump and the hydrobromic acid tank. 2.2.2 After checking that there are no leaks in the heat exchanger and its connecting pipelines, gradually open the steam control valve and gradually increase the temperature. The heating of the distillation tower should not be too fast to avoid damaging the tower body. For new towers, the heating time should be at least 2 hours, and the normal heating time can be 1 hour (winter can be extended appropriately). 2.2.3 When the tower temperature reaches 60℃, gradually increase the hydrobromic acid flow rate, increase the steam quantity, and gradually open the chlorine supply valve. Control the chlorine gas entering the tower through the rotary flow meter (it is strictly prohibited to open the ch
