Process Equipment and Plant Design Pick out the wrong statement pertaining to the design of the distillation column. If sufficient slot area is not provided, the gas may pass through the skirt clearance 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 The purpose of the slot is to disperse the gas into the liquid in the form of small bubbles If sufficient slot area is not provided, the gas may pass through the skirt clearance 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 The purpose of the slot is to disperse the gas into the liquid in the form of small bubbles ANSWER DOWNLOAD EXAMIANS APP
