1. [25 marks] The process data of a stream is as follows: - Gas flowrate =285,000Sm3/d,MW=30, visc =0.012cP,Z=0.97 - Water flowrate =10,000m3/d (actual), water density =1020kg/m3, visc = 1.7cP - Pressure =700kPag - Barometric pressure =90kPa - Temperature =3C - Assume that the water content in the gas is negligible - Standard conditions are 101.325kPaa and 15C. a) Size the internal diameter (ID) of a vertical separator, using: K factor =0.05m/s b) Calculate the minimum required height from bottom of vessel to low shutdown level (H8, according to GPSA sizing method) to provide 5 minutes residence time for the liquid. (Ignore the volume of the elliptical heads) Gas Density Pv=RTZP(MW)R=gasconstant=8.314kPam3/(kgmolK) Vertical Separator - Basic Design Equation Vt=Kg(lq)
