For the tube bundles of crude oil constant top circulation heat exchangers in the petroleum refining industry, is it appropriate to use high-efficiency heat exchanger tube bundles in such operating conditions?
Thread Content
The image below shows the atmospheric and vacuum distillation unit in petrochemical industry, specifically the tube bundle of the crude oil atmospheric overhead circulation heat exchanger. Model: FB900-210-25-4, Material: 10#, Operating conditions: Shell side: crude oil, temperature 172°C, pressure 0.79 MPa. Tube side: medium, normally pressurized circulation, temperature 132°C, pressure 0.71 MPa. This tube bundle uses high-efficiency heat exchange tubes with threaded tubes; is such a setup appropriate, as shown in the image?
Under such operating conditions, it is appropriate to use threaded high-efficiency heat exchange tube bundles. Since crude oil and its associated circulating fluids require extensive heat exchange, high-efficiency heat exchange tubes can provide a larger heat exchange area and improved heat transfer performance, thereby helping to enhance the thermal efficiency of the system. At the same time, considering the operating temperature and pressure ranges, it is also necessary to choose materials that are resistant to high temperatures and pressures. .
It is recommended to use duplex steel or titanium steel
