Heat exchanger cleaning
Thread Content
Shell-and-tube heat exchanger, water flows in the tube side and gas flows in the shell side; the gas contains sulfides； During equipment maintenance, sulfur is present in the shell side (between the tubes). What methods are available to effectively remove this sulfur?
It’s quite difficult. If the pipes are not completely blocked, online chemical cleaning yields relatively better results. As for which agent to choose, that’s unclear.
Can filtering be done first before going to the heat exchanger?
If it can’t be disassembled, then there’s something wrong with this design itself; chemical cleaning is the only option, but S is also difficult to clean
The amount of semi-water gas is relatively large, making it difficult to feed the gas into the boiler system
Who has the contact information for a company that does cleaning services? I’d like to ask them
Ammonia synthesis plants? It’s not sulfur, right? It’s coal tar, with a high content of sulfides. In our cases, steam is used in the shell side of the heat exchanger, while high-pressure washing is used on the tube side

Is this patent useful? CN86102133 – A method for dissolving sulfur and its solvents
