Problems with the light benzene condensation cooler?
Thread Content
The light benzene condensation cooler consists of two tubular heat exchangers, one at the top and one at the bottom; the one at the top is used to condense the gas into a liquid, while the one at the bottom further reduces the temperature. What are the differences between these two heat exchangers in terms of design and manufacturing? Thank you.
I don’t think there’s any difference; it’s just that the condenser and the cooler are combined together, with different fluids flowing inside them, which results in different functions.
Your light benzene condensation cooler is composed of three shell-and-tube heat exchangers, right?
In my opinion, there is no difference between the two in terms of heat exchange mechanism. However, the diameter of the inlet and outlet pipes for the cooling medium gradually decreases. The purpose is to improve the cooling effect
Different pipe diameters are required; for condensation phase change, the diameter of the gas inlet pipe must be large enough. In the case of cooling without phase change, the inlet and outlet pipes can have the same diameter
