Evaporate Process PID diagram can be created using EdrawMax or EdrawMax Online as several predefined templates can be used. As the below PID diagram suggests, evaporation technology is used in any process that requires the concentration of a stream by removal of water or another solvent. The method of evaporation is energy-intensive; any evaporator system design approach needs to take significant consideration into the heat recovery and overall utility usage of the final system design. There are different types of evaporators like falling film evaporator, rising-falling film evaporator, flash evaporator, forced circulation evaporator, and others. The entire evaporator duty can be segregated into multiple evaporator effects. In essence, the steam economy of the system is linear to the number of effects used in a design.
