Effects of processing variables on evaporator operation: Effect of pressure: Pressure in the evaporator sets the boiling point of the solution (T 1 ). Steam pressure determines the steam temperature (T s ) Since q = U A (T S – T 1 ), larger values of (T S – T 1 ) will help reduce the heat-transfer area needed and hence the cost of evaporator.
