Sulfur recovery, increased pressure in the inlet pipeline for exhaust gas treatment
Thread Content
When the off-gas generated from the Claus unit enters the hydrogenation reduction section, it is observed that the pressure in the pipe section prior to the hydrogenation furnace gradually increases； Meanwhile, the inlet pressure for the hydrogenation reaction is also rising, while the pressure at the rear end after the reactor outlet remains low. How to solve this problem?
The possible reasons are blockages inside the pipeline or a malfunction in the pressure control device. The steps are as follows: 1. Check the inlet pipeline for any physical blockages, such as sulfur crystals or dirt. 2. Inspect and clean the filters and valves. 3. Check whether the pressure control devices (such as control valves) are operating properly to ensure there are no faults. 4. If all the above checks are satisfactory, consider whether there are any irrational aspects in the system design; it may be necessary to adjust the processes or increase the pumping capacity. After resolving these issues, monitor the pressure changes again to ensure the system returns to normal operation. .
The diameter of the exhaust pipeline at the hydrogen inlet is 18 inches; is the probability of blockage high in this case? Or could it get blocked at the entrance to the burner?
Is Klaus burning ammonia? Are there any issues with temperature or anything else during normal operation?/
