You now have unlimited* access to books, audiobooks, magazines, and more from Scribd. Our highly automated production facility delivers quality equipment, meeting international standards. One kind of evaporator is a radiator coil used in a closed, compressor-driven circulation of a liquid coolant. The concentrating and separating section removes the vapor being produced from the solution. The condenser condenses the separated vapor, then the vacuum or pump provides pressure to increase circulation.[5]. An evaporator/evaporative-process can be used for separating liquid chemicals as well as to salvage solvents. Processes, 8(11), p. 1509 ...
