Is it better to perform gas-liquid separation under high pressure or low pressure?
Thread Content
Under the conditions satisfied by other processes, is it better to use a gas-liquid separator at high pressure or low pressure?
If both high pressure and low pressure are acceptable, I think low-pressure separation is more thorough.
Why? Is there any evidence for it?
The contents within the pipeline are a mixture of gas and liquid; once they enter the tank, the increased volume leads to a separation of the gas and liquid due to pressure changes. This separation becomes even more apparent as a result of the defogging effect. As for whether high or low pressure is better, I don’t think there is any particular advantage; moreover, the efficiency of the defogger and temperature changes affect the separation effect
Low pressure allows the gases dissolved in the liquid to be desorbed more completely, resulting in a more thorough separation
