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
