Seeking advice on how to better condense volatile gases in the design and construction of negative pressure systems
Thread Content
In the design of negative pressure systems, it is very important to condense condensable gases into a liquid as much as possible. I’m very interested in knowing how to condense condensable gases from a design and piping perspective; I hope experts can offer some guidance.

Appropriately increase the margin for the condenser, design a separate cooler on the pipeline leading to the vacuum pump, and install a steam-water separator!
Is it necessary to use baffles or screens inside the soda separator to effectively separate the vapor from the liquid? Is just a sealed storage tank enough?
Are there any requirements regarding the piping of the condenser’s inlet and outlet lines, such as height, slope, elbows, etc.?
Soda separators have a standard design; those equipped with screens or baffles represent different structural versions. The process design for separators without internal components requires greater precision
To better condense the condensable gases in vacuum pipelines, I believe the key lies in ensuring that the area of the condenser at the end of the vacuum pipeline leading from the negative pressure device, as well as the heat transfer capacity of the cooling medium, are sufficient; no special requirements exist regarding the piping itself.
Our current design does not include a vapor-liquid separator; instead, there is only a horizontal tank with a capacity of around 15 M3 that serves as the suction inlet for the vacuum pump, with a cooler connected to it ahead of the tank.
The condensable gas drawn from container A is connected via pipeline B to cooler C and then to the vacuum equipment; the route of pipeline B is designed based on the distance and location between A and C, with a general slope of 1:105!
