How is the diameter of a liquefied gas desulfurization tower determined?
Thread Content
RT. I recently encountered an absorption tower that uses an MDEA aqueous solution to absorb hydrogen sulfide from LPG. PROII can be used to simulate the liquid-liquid extraction process, but I’m not sure how to calculate the diameter of such a tower. I couldn’t find any information on this in books related to tower design. Could anyone among you tell me how to calculate it?
The tower diameter is also determined based on the vapor flow rate and vapor density inside the tower, just as in the design of other towers.
It is MDEA desulfurization for liquefied petroleum gas LPG, with the entire tower in liquid phase.
Are you sure that at the corresponding temperature and pressure, LPG is in a completely liquid state, rather than a vapor-liquid mixture?
Using the same calculation method as for towers, lighter substances are considered to be in the gas phase, while heavier ones are considered to be in the liquid phase.
It is determined to be a fully liquid-phase system, with MDEA entering from the top of the tower and LPG entering from the bottom.
