Process Equipment and Plant Design Back-trapping in a distillation column results due to Excessive liquid gradient over the tray Low reflux ratio Low gas velocity High gas velocity Excessive liquid gradient over the tray Low reflux ratio Low gas velocity High gas velocity ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Pick out the wrong statement pertaining to the design of the distillation column. None of these Generally, a skirt clerance of 0.5" to 1.5' is recommended to prevent plugging of the slots by residue build up If sufficient slot area is not provided, the gas may pass through the skirt clearance The purpose of the slot is to disperse the gas into the liquid in the form of small bubbles None of these Generally, a skirt clerance of 0.5" to 1.5' is recommended to prevent plugging of the slots by residue build up If sufficient slot area is not provided, the gas may pass through the skirt clearance The purpose of the slot is to disperse the gas into the liquid in the form of small bubbles ANSWER DOWNLOAD EXAMIANS APP
