Q1) 2 in stainless steel tubular reactor is packed of 1/4 in (dp) diameter catalyst pellets with a void fraction of 50%. A continuous gas phase reaction takes place in the reactor with conversion 80% and the following information: 2nd order reaction: 2A(g)B(g)+2C(g)k=25(ft3lbmole)1s1 Flow rate of B150lb/hr. Feed temperature and pressure are 400C and 5atm respectively. Outlet pressure is latm Average molecular weight of A and B are 50 and 60 respectively Viscosity is 0.008cp. Catalyst bulk density is 70lb/ft3 and its cost is $5/lb. Calculate a) Required volume, ft3 b) Tube length, ft c) No of tubes d) Cost of reactor with catalyst at 2002 e) Suggest the expression for 2011 reactor cost estimation (30pts)
