Process Equipment and Plant Design Overall distillation column efficiency for most of the refinery columns can be given by (for μ = 0.07 - 1.4 cp and relative volatility < 4) (where η = overall column efficiency, % μ = molal average viscosity of feed at average column temperature and pressure, cp Δp = pressure drop per tray, psi) Η = 17 - 61.1 log μ Η = 0.25 log μ - 1.67 Η = 24.6 (Δp/μ) Η = 1.66 - 0.25 log μ Η = 17 - 61.1 log μ Η = 0.25 log μ - 1.67 Η = 24.6 (Δp/μ) Η = 1.66 - 0.25 log μ ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Pick out the wrong statement about the design of seive plate column and the bubble cap column. Weir length for a bubble cap plate is the same as that for the seive plate Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate Weir height for a bubble cap plate column is the same as that for a seive plate column The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns Weir length for a bubble cap plate is the same as that for the seive plate Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate Weir height for a bubble cap plate column is the same as that for a seive plate column The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns ANSWER DOWNLOAD EXAMIANS APP
