thanks! what pressure the pump of vacuum should be make for a good separation of air? i need that only air separate, not steam.Baluncore said:Welcome to PF.
Any process carried out at a low pressure, can probably also be done in a continuous flow, after an orifice that reduces the pressure in a chamber, before the inlet to a pump that restores the outlet pressure. A separate pump would be needed to remove the gas from the chamber.
By coupling a hydraulic motor with a pump having a slightly greater capacity, better efficiency would be achieved. Driving the combination would take less power than an orifice and a pump.
ok, i understand, so at 50°F with a pressure near 0.0121atm i can take all the air. perfect!Baluncore said:When the water is at the boiling point there will be almost no dissolved gasses to remove.
The vapour pressure of water varies with temperature, you will always get some water vapour with the air.
You need some “steam” to be sure there is no air left in solution.
You may need to study the phase diagram for water or the steam tables.

Maybe a cold condenser stage could produce liquid water from the recovered gasses.kart1987 said:i need a flow of air without vapour. do you know if a steam trap exists?
exactly! I'm primarily trying to extract O2 from water, but i know that some CO2 could be in water, and for this reason i need a scrubber for CO2. i don't know the flow of CO2.Baluncore said:Are you producing degassed water and getting O2 as a bonus or are you primarily trying to extract O2 from water.
Is the scrubber for CO2 ? What is your estimated CO2 yield per litre ?
Degassing water is the process of removing dissolved gases from water. This is important for air quality because when water is agitated or heated, these dissolved gases can escape into the air and contribute to air pollution. By degassing water, we can help improve air quality and reduce potential health hazards.
Degassing water can significantly improve the taste and odor of water. This is because dissolved gases can give water a stale or unpleasant taste and odor. By removing these gases, the water will taste and smell cleaner and fresher.
There are various methods used to degas water, including aeration, vacuum degassing, and membrane degassing. Aeration involves exposing water to air, which allows the gases to escape. Vacuum degassing uses a vacuum to remove gases from the water. Membrane degassing uses a semi-permeable membrane to separate dissolved gases from the water.
No, degassing water does not completely remove all gases from the water. Some gases, such as carbon dioxide, are more easily removed than others. Additionally, some gases may be tightly bound to the water molecules and cannot be removed through degassing.
Degassing water has numerous benefits for industrial processes. It can help prevent corrosion in equipment, improve the efficiency of chemical reactions, and reduce foaming and air bubbles in products. Additionally, degassing water can help ensure the purity and consistency of products, which is crucial in industries such as pharmaceuticals and food and beverage manufacturing.
