Process Equipment and Plant Design The slope of operating line in the rectifying section of a distillation column is unity, if the reflux ratio is 1 0 Minimum ∞ 1 0 Minimum ∞ ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design A perforated plate has holes of diameter dh arranged in a pitch ph. Each hole has a tube of I.D. dt passing through it. The ligament efficiency is given by (ph - dh . dt/2)/ph (ph - dt)/ph (ph - dh)/dh (ph - dh)/ph (ph - dh . dt/2)/ph (ph - dt)/ph (ph - dh)/dh (ph - dh)/ph ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In actual operation of distillation column, the vapour is not distributed uniformly among the bubble caps, primarily because of the Lower static submergence Liquid gradient on the tray Small downcomer liquid seal Lower skirt clearance Lower static submergence Liquid gradient on the tray Small downcomer liquid seal Lower skirt clearance ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design 25 per cent cut segmental baffle means that the baffle Height is 25% of the I.D. of the shell Spacing is 75% of its height Height is 75% of the I.D. of the shell Width is 25% of its height Height is 25% of the I.D. of the shell Spacing is 75% of its height Height is 75% of the I.D. of the shell Width is 25% of its height ANSWER DOWNLOAD EXAMIANS APP
