Experts: Acidic water enters the device, then the storage tank, and subsequently the tower; over time this can lead to blockages in the tower trays as well as a decrease in the heat exchange efficiency of the reboiler at the bottom of the tower； We now install a filter at the point where the material enters the device; as a result, the raw water contains impurities such as heavy oil and coke dust ； It got clogged just a few hours after being put into use, and the backflow cleaning effect was poor ； How has everyone set up this filter? Can the filter be placed behind the acid water pump? In this way, the acidic water is deoiled in the storage tank, with most impurities settling within the tank; only the impurities are removed at the pump outlet, ensuring long-term operation of the acidic water stripping process. Welcome, experts, for your guidance.
Ours is also at the location where the equipment is installed; we all disassemble it for cleaning. The issue with heavy oil and coke powder is a problem of the upstream equipment! Impurities can settle within the storage tank, but the inlets of the acid water pumps are located at the bottom of the tank; therefore, it remains necessary to clean the filters at the pump inlets, and this can also lead to equipment damage due to vacuum conditions. There’s no need for that; the problems with the upstream equipment should be resolved by that equipment itself. After all, acidic water stripping isn’t capable of treating every type of water
We install filters at the point where the fluid enters the device; we clean them by taking them apart. The issue with heavy oil and coke particles is a problem of the upstream devices!
Our filter is located between the raw water tank and the feed pump
Two filters, one in use and one as a backup, with a pressure difference gauge; when the pressure rises, it switches to clean the filter.
