Reasons for the high resistance in the sulfur recovery system
Thread Content
The reasons for the high resistance in the sulfur recovery system are summarized as follows: First, the purging of the system before its initial operation was not optimal, leaving dead corners in the process. If the Klaus reactor is to be isolated, it should be purged one by one. The temperature of the second system is generally low (with emphasis mainly on the temperatures of the heating heat exchanger and the equipment used for waste heat recovery). Parameters of the third process gas (excessively high concentration of acidic gases or changes in composition). Leakage occurred in the fourth process equipment. The fifth liquid pipeline is blocked.
Is the system pressure high right from the start of operation?
There are quite a few reasons for high pressure in the sulfur system: blocked valves, collectors, tube bundles, sulfur blockages, pipe blockages, etc
There are many reasons for high system resistance: particular attention should be paid to blockages caused by liquid sulfur and acidic gases forming salts. It is not known whether the furnace uses ammonia for combustion; if so, it is necessary to check the furnace temperature to ensure complete combustion of ammonia.
I agree with everyone’s additions. I hope we can communicate more in the future.
1. Problems with heat tracing of liquid flow pipelines 2. Carbon deposition due to methanol in acidic gas streams 3. Blockage in the hydrogenation section of the quench tower 4. Blockage of the cooler mesh 5. Blockage in other heat exchangers
It is best to check the inlets and outlets of the condenser tube bundle during maintenance, as there is a high possibility that catalyst dust has accumulated at the ends of the tube bundle
