During maintenance, crystalline blockages were found in the heat exchangers and fiber membranes of the liquid hydrocarbon desulfurization system, which severely affected the efficiency of desulfurization. The concentration of fresh alkali solution in our device is 26%, while the concentration of alkali solution in the system is 10–15%; 5% of the alkali solution (based on the liquid level in the container) is replaced weekly. I’m not sure if rust in the blown-in air will affect crystallization; the iron ion concentration in the alkaline solution is 86.52 mg/L. How to solve this problem
Under the water circulation mode, let’s see how it works
The air supply volume is very small, so this factor can be ignored
