In a horizontal U-tube shell-and-tube condenser, can the condensing gas flow through the tube side?
Thread Content
The pressure of the condensed gas is not high, at around 0.1–0.2 MPa (G). The heat exchange area of a standard BJ21S unit is insufficient for this purpose; therefore, it was considered to have the condensed gas flow through the tube side. However, given that the pressure of the condensed gas is low, will this approach work? I seek advice from those with more experience
Piping is generally used for media under high pressure, let alone gases; so why not use the shell side instead? Moreover, with low pressure to begin with, such a large pressure drop can easily lead to liquid sealing, making it difficult to implement.
The ordinary heat exchange efficiency isn’t sufficient; those with baffles in the shell side would work better
The pressure of the condensed gas is high, so it is appropriate to use the tube side.
