Process Equipment and Plant Design Pick out the wrong statement pertaining to the design of a horizontal tube evaporator. Liquor flows inside the tube, while the steam is outside submerging the tube It is suitable for process, in which the final product is a liquor instead of solid Its usual dimensions are: tube dia = 2-3 cms; evaporator body dia = 1-4 metres and evaporator height = 2.5-4 metres It is unsuitable for concentrating those liquids, which form a scale or deposit salt Liquor flows inside the tube, while the steam is outside submerging the tube It is suitable for process, in which the final product is a liquor instead of solid Its usual dimensions are: tube dia = 2-3 cms; evaporator body dia = 1-4 metres and evaporator height = 2.5-4 metres It is unsuitable for concentrating those liquids, which form a scale or deposit salt ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Pick out the wrong statement pertaining to the design of the distillation column. Generally, a skirt clerance of 0.5" to 1.5' is recommended to prevent plugging of the slots by residue build up None of these 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 Generally, a skirt clerance of 0.5" to 1.5' is recommended to prevent plugging of the slots by residue build up None of these 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
