Process Equipment and Plant Design Smaller sized packings are generally dumped to the packed columns, and the large ones of size greater than __________ mm are stacked individually, which provides better control over bed porosity and offers lower gas pressure drop. 25 150 75 50 25 150 75 50 ANSWER DOWNLOAD EXAMIANS APP
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 = 1.66 - 0.25 log μ Η = 0.25 log μ - 1.67 Η = 24.6 (Δp/μ) Η = 17 - 61.1 log μ Η = 1.66 - 0.25 log μ Η = 0.25 log μ - 1.67 Η = 24.6 (Δp/μ) ANSWER DOWNLOAD EXAMIANS APP
