Selection of heat exchangers?
Thread Content
Which type of heat exchanger should be used to heat the CH4 that has passed through the compressor from 30°C to 165°C? What is the heating medium? Can a heating furnace be used for heating?
In shell-and-tube heat exchangers, the heating medium is generally high-pressure steam or heat transfer oil; using a furnace for heating is too dangerous. It is recommended to use threaded tubes for heat exchange tubes
I agree with the opinion above; the gas coming out of the compressor already has a high pressure, and the pressure of the heating medium is generally high as well. It is recommended to use a shell-and-tube heat exchanger, with the high-pressure medium flowing inside the tubes. If both sides involve gas, threaded tubes represent a good choice
I just did the calculations – to heat this with steam, at least 8 kilograms are required. The cost-effectiveness needs to be considered
Indeed, it is recommended to use a shell-and-tube heat exchanger; if needed, feel free to consult us as we specialize in shell-and-tube heat exchangers:lol
It is recommended to use a shell-and-tube heat exchanger, with medium-pressure steam as the heating medium.
There should be two types of configurations for this application: one is the shell-and-tube heat exchanger, and the other is the fully welded plate heat exchanger. Compared to the former, the fully welded plate heat exchanger has higher efficiency; you can develop two options and then compare them in terms of cost-performance
Oil is heated using a plate heat exchanger, which features a high heat transfer coefficient and excellent heat exchange performance. It’s a great choice indeed.
