Scope

Main Technical Content: 2.1 Preparations Before Starting Up 2.1.1 Prepare protective gear and emergency rescue supplies. On-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 and slowly open the supply and drain valves of all equipment using cooling water. Control the cooling water pressure to no more than 0.3MPa to avoid damaging cooling equipment and 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 steam and chlorine pipelines and valves to ensure no leaks. 2.2 Start-up Operations 2.2.1 Open the hydrobromic acid pump inlet valve. After the hydrobromic acid fills the pump body, start the hydrobromic acid pump and slowly open the pump outlet valve. Control the hydrobromic acid feed rate to about 1m3/h into the distillation tower. 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, slowly open the steam control valve and gradually increase the temperature. The distillation tower heating process should not be too rapid to avoid damaging the tower body. For new towers, the heating time should be at least 2 hours, and during normal operation, it can be 1 hour (with appropriate extension in winter). 2.2.3 When the tower temperature reaches 60°C, slowly increase the hydrobromic acid flow rate, increase the steam quantity, and slowly open the chlorine supply valve. Control the chlorine gas supply through the rotary flow meter (do not open the chlorine valve too quickly to avoi
