In vacuum distillation, is it necessary to install a level gauge in the pre-pump condenser?
Thread Content
The liquid level gauge may have the following problems: 1. The liquid level gauge adds an additional point of leakage, and distillation is carried out under high vacuum conditions (several hundred pascals)； 2. There is a concern that danger may arise if air leaks in, as the distillation material could react with the air. However, without a level gauge, it is not possible to visually monitor the level of condensate in the tank; one can only decide on fixed intervals for draining it. Fellow sailors, share your opinions
The opening of the level gauge is so small, so the problem of leaks should be easy to resolve, right?
Adding one is no problem; it’s all flange-connected, so what’s there to worry about? !
Compared to other leakage points, the leakage point of the level gauge is too small.
It can be added; adding it helps with control
