Selection of the heat exchanger at the top of the vacuum tower
Thread Content
Hello everyone, I need a heat exchanger for the top of a tower that can achieve a vacuum level of 100 Pa. Which type of heat exchanger can result in the lowest pressure drop? The design institute suggested using a cold trap, but I’ve found quite a lot of information on this topic, yet it’s not very comprehensive and it’s difficult to understand. I’ve seen before that coil-type heat exchangers are used for this purpose! They say it’s a cold trap! Everyone, please give some suggestions
The Mechanical section has a dedicated heat exchange forum, where it’s easier to communicate @ZhizheMing @jacques0920
100 Pa isn’t such a high level of vacuum; a shell-and-tube heat exchanger will suffice, as the pressure loss in coiled tubes is somewhat high……
A shell-and-tube heat exchanger is sufficient; that’s what we use
