Today’s companies and design institutes are too lazy; the calculation of towers is mostly left to the manufacturers of those towers.
Two aspects: spray density and circulation capacity
For the desulfurization of liquefied gas, amine solution is used for extraction with sulfur-containing liquefied gas. I believe this relies on the principle of extraction as discussed in terms of chemical distribution ratios; during extraction, the ratio of the molar concentration of hydrogen sulfide in the desulfurized liquefied gas to that in the enriched solution equals the equilibrium constant K. This law is used to determine how much amine solution needs to be circulated in order to bring the hydrogen sulfide level in the liquefied gas within acceptable limits
