hi every body
Im simulating a hybrid solvent mercaptan removal process by HYSYS, the method which i apply to converge the ABSORBER and STRIPPER COLUMNs is ADVANED MODELING, i know this method must be applied because of the presence of mercaptan and COS, but there is a problem, stripper column doesnt run...it just run by using EFFICIENCY method... the column is trayed
can anybody give me a help?
thanks in advance
