What is used when gas can pass through but liquid cannot?
Thread Content
I want to add something to the pipeline so that gas can pass through while liquid cannot. What can be used?
There are many things that can be used. I think a gas-liquid separator is a common option; it’s also inexpensive.
Actually, it’s sufficient to use a steam trap to separate the water.
I want to add a passage on the side wall to allow the gas in the pipeline to escape, without allowing the liquid in the pipeline to flow out
It is safer to use a gas-liquid separator, and then configure an appropriate level detection and control circuit based on the amount of material.
If the flow rate is high, a tank-type gas-liquid separator should be used, with a demister added to the gas phase pipeline at the top； If the flow rate is low, using a single pipe is sufficient to achieve gas-liquid separation.
It’s very simple: just install a separator on the horizontal pipe, add a level measurement indicator, and fit a level control valve at the bottom to regulate the liquid level. If the liquid volume is high, a demister can be installed at the outlet. :victory:
If the pipe diameter is not very large, a \"steam distributor\" or a \"waste steam oil separator\" can be used; this is described in the \"Process Piping Installation Design and Construction Manual.\" However, there are requirements regarding standard pipe diameters: for \"steam distributors\", the diameter ranges from DN50 to 300； “Waste steam oil separator” DN80～200.
It can be achieved. Based on the contact angle of the liquid with the material, porous materials with a contact angle greater than 90° are selected, and the pore size is determined using the KELVIN equation. Capillary force prevents liquids from passing through, but gases can.
