Selection of heat exchanger material and calculation of heat exchange area
Thread Content
The company has a new Chinese-style project involving batch reactions in reactors. The feed for each reactor consists of 3 tons of water and 2 tons of benzyl chloride (monochlorotoluene), which react at a temperature of 120 degrees Celsius. During the reaction, water evaporates, and part of the benzyl chloride as well (with a boiling point of 179 degrees Celsius) will boil off as well. It is necessary to cool these substances using a heat exchanger before returning them to the reactor; the cooling water has a temperature of 25 degrees Celsius and a pressure of 0.5 MPa. Since benzyl chloride is subject to both chloride ion corrosion and the good solvating properties of benzene derivatives, I consulted the process team earlier, and they recommended using a graphite heat exchanger (one that has not been used before). 1. Could you help calculate the heat exchange area of the heat exchanger?2. Which type is more suitable for these operating conditions – tubular type (with water flowing in the shell side and the fluid to be heated flowing in the tube side) or honeycomb type – and which one has a lower cost?
3. Please recommend some excellent domestic manufacturers of graphite heat exchangers
Since we need to purchase a heat exchanger, it’s best to let the equipment manufacturer do the calculations. The graphite heat exchangers we use are from Nantong, Jiangsu
There are many in Nantong, Jiangsu; you’ll know once you go and see them~
