The liquefied gas desulfurization tower often gets clogged; the tower should be equipped with regular packing. I hope experts can analyze this issue

Our liquefied gas desulfurization tower often gets clogged, and it needs to be cleaned every little over a month. Preliminary analysis suggests that the coke powder present in the coked liquefied gas is the cause; could the suspended solids in the lean liquid also have an impact? Are there any other reasons?
1. Coking liquefied gas and dry gas desulfurization towers are indeed prone to clogging. 2. The possibility of an issue with the quality of the amine solution cannot be ruled out; it tends to foam very easily.
It is also related to the processing load; when the load increases, the pressure drop in the tower rises as well, and this phenomenon occurs.

If it is confirmed that the blockage is caused by dust from the coking tower, efforts should be made to reduce the amount of dust carried in the rich gas, thereby addressing the problem at its source. I wonder if you have started using that extremely cold oil? How effective is it?
Yes, the load is high, so the level of the tower fluctuates quite a bit
Well, I’m not sure about this. Our LPG desulfurization takes place in the sulfur recovery unit, not in the coking process, so the process flow isn’t very clear:lol
Could considering replacing the packing with vertical sieve plates be an option? We have carried out many desulfurization renovation projects; vertical sieve plate towers have a greater processing capacity and better resistance to clogging, so it is recommended that you give them consideration.
