BEM700-2.5/1.6-200-9/25-4I Fixed tube sheet heat exchanger design
Abstract: Fixed tube sheet heat exchanger is the energy-saving equipment heat transfer material between an implementation is a process equipment in the petroleum, chemical, petrochemical, metallurgical, power, light industry, food industry in general applications. In the oil refining, chemical means around the heat exchanger of the total number of devices 40%, 30% -45% of the total investment. With the development of energy-saving technology, applications continue to expand, the use of high temperature and low temperature heat exchanger heat recovery has brought significant economic benefits. On the use of geothermal, solar, nuclear, waste heat recovery, wind, national governments, research structures and companies have stepped up efforts to invest in the next few years, heat exchanger technology will be a great space for development.
