Packed tower calculation

Thread Content

In our chemical engineering process, there is an absorption tower used to absorb hydrogen sulfide from gases that contain a large amount of water vapor, using alkaline solution. The conditions are as follows: normal pressure or slight vacuum, a steam flow rate of 6,000 kilograms per hour, with 800 kilograms per hour of hydrogen sulfide present; the purification is carried out using circulating alkaline solution, with two towers – the first tower uses co-current absorption while the second tower uses counter-current absorption. Currently, we are seeking experts to help verify the calculations: with a 30% alkaline solution flow rate of 50 cubic meters per hour, and using 250Y regular stainless steel orifice plate corrugated packing, what diameter tower would be appropriate?
