I haven’t encountered that before; could it be that the circulating water heat exchanger is leaking? Still, circulating water entered the underground tank, contaminating the solution. Check it out right away.
During the major repair, leaks were checked and repaired in the CO2 cooler.
Seal the leaks first, then remove them. Replace the solution gradually; the water that evaporates can also be replaced with deionized water first
Under what conditions does activated carbon achieve the best absorption efficiency?
How much iron is there? ? The newly prepared make-up fluid is passed through an activated carbon filter, which not only removes insoluble impurities but also adsorbs organic substances that cause foaming. However, activated carbon can adsorb DEA and defoamers present in the solution, and it can form organic complexes with vanadium pentoxide at high temperatures, causing the activated carbon to clump together and lead to blockages. Therefore, an additional mechanical filter is installed, which is of stainless steel wire mesh type.
