Regarding the problem of heating up the hydrogenation reactor
Thread Content
The process of my device is from the tail gas liquid separation tank to the tail gas heater, then to the hydrogenation reactor, into the steam generator and to the quenching tower. There is no line to remove the tail gas boiler in the middle. Excuse me: What medium is best to use to heat up the hydrogenation reactor? If fuel gas is used, can it enter the quench tower? Please help Haiyou, thank you! This post was last edited by Ma Hai on 2009-3-23 02:54 ]
Is there a circulation line? You can consider using the circulation line to heat up.
Check to see if there is a nitrogen line and a steam line inserted into the inlet of the exhaust gas heater. If there is, there is something wrong with the design. Use nitrogen.
The hydrogenation reactor can be heated in two ways: 1. Use sulfur fume ； The flue gas heated by sulfur is used for heating. 2. If a circulation line is designed, as mentioned on the second floor, the temperature can be circulated.
If circulating slow gas (nitrogen) is used to raise the temperature, at what temperature can the exhaust gas be introduced? Is the quenching tower put into use?
If flue gas cannot be used, use nitrogen and control the temperature the same as flue gas. Let the bed reach 240-250 degrees. Wait for pre-vulcanization. When heating up, control the inlet temperature, 20-30 degrees/h
Control the hydrogenation reactor bed to heat up to a constant temperature of 200°C at a rate of 20-30°C/h, establish a cold cycle and pre-sulfide the hydrogenation catalyst.
First use nitrogen circulation to heat up and then use sulfur production tail gas to vulcanize
