Hi, Im asking for helping me with investigation ofHCl removal column with 70 etages (condenser is 1st). Column have two feeds. 1st gaseous on 28th etage( m=10-14 tones/hour, t=10-20°C, mass comp: HCl 0,66; EDC 0,06; VCM 0,24) and second liquidus on 32rd etage (ˇm=26-30 tones/hour; t=50°C, comp w/w HCl 0,07, EDC 0,62, VCM 0,31). column have 70 etages, , total condenser (P=916 kPa), limits: 20 ppm VCM , operating temperature is about -34,5°C.From condenser goes 2 streams, 1st gaseous, and 2nd liq (2tones/hour) Total Reboiler has P=986kPa, limits for HCl 1 ppm,usualy works in 83-85°C. I ussualy work with PR thermodynamics. I ll be thankfull for any help. Does exist any reason, why its never works in flowsheeting document?
