In HYSYS, for horizontal vessel sizing, why do the calculated vapor space height and allowable velocity not match? For example, I set a maximum allowable velocity, and it gives a vapor space height and diameter. When I use that diameter to recheck the vapor velocity, the result is higher than the maximum allowable velocity I set. What is the reason? Is there a problem with my parameter input

I am not familiar with Hysys horizontal vessel sizing. The statement of the problem suggests that the user sets a maximum allowable vapor velocity. Is this for a two-phase separator? There are two directions for vapor flow in a usual two-phase separator. Are you setting the maximum horizontal velocity? What is the basis for this input? The tech support for the software provider would be the best place to get the answer you seek. The example you provided contained no data to evaluate your input or results.
