Leak in solvent regeneration air cooler
Thread Content
Has the solvent regeneration air cooler in your unit leaked? The air coolers here leak frequently; what could be the reason?
Is it a leak in the air-cooling tube or at the tube end? If there is a leak in the tube bundle, it must be caused by corrosion; increasing the temperature after air cooling appropriately helps to reduce corrosion.
In fact, the amine liquid regeneration tower may have two air coolers, one for acidic gas and one for the lean amine liquid. I don’t know which one is being asked about?
It might be thermal-steady-state salt corrosion; otherwise, the material should be upgraded
Is thermostatic salt really that effective? We also have a solvent regeneration system that uses catalysis alone; it has been in use for 8 years with no issues despite being air-cooled. The problem now arises in systems that use desulfurizing agents for catalytic processes, coking units, atmospheric and vacuum distillation units, and gas holders
