How to solve the problem of high resistance in acid gas pipelines
Thread Content
The resistance in the pipeline for vacuum potassium carbonate desulfurization increases significantly after some time, forcing shutdowns for cleaning. Do experts know of any ways to avoid this phenomenon?
Why does the resistance increase? Are there ammonium salt crystals?
A black, asphalt-like substance with high hardness
It is recommended to analyze these substances first, determine their components, and then make a decision.
It is mainly due to impurities in the desulfurization liquid; if possible, lower the temperature of the acid gas, and install U-bends or filters on the acid gas pipelines. I don’t know which company you work for?
Control the temperature of the acidic pipeline to prevent salt formation, and also make sure to remove liquid from the pipeline in a timely manner.
For the impurities carried in the gas before desulfurization, a practical approach is to control the temperature of the acid gas after the separator, which can extend the operating cycle of the pipelines
