The Design of E201 Lye heat exchanger
Abstract: In industrial production, the device which can make the material transfer their heat called heat exchanger. It is process equipment in chemical, oil refining, power, atomic energy, and many other industrial. For the rapid development of the chemical, oil refining and other industrial, the heat exchanger is particularly important. Usually in the construction of the chemical plants, heat exchanger accounted for about 10-20% of the total investment. In oil refinery, heat exchanger accounted for about 35-40% of all process equipment investment. In the heat exchanger equipment, the most widely used is the tube-shell heat exchanger. At present, this kind of heat exchanger is used as a traditional standard heat exchanger, is widely used in many industrial departments. Especially in chemical production, whether domestic or abroad, in all of the heat exchanger equipment, it is still dominant. This design through the understanding of the heat exchanger, designed a Lye heat exchanger transfer.
Key words: shell and tube heat exchanger; fixed tube-sheet exchanger; Stress Analysis; the structure design
