Process for dissolving gas into a liquid

摘要

A gas is dissolved into a liquid by first pressurizing the liquid to a predetermined level. The pressurized liquid is then directed into a hydrocyclone to form a vortex stream having an evacuated central area. The hydrocyclone has an inlet aperture size and configuration and a barrel diameter and length optimized for liquid particle movement through the liquid vortex stream. Gas is injected into the evacuated area for absorption into the liquid vortex stream. The liquid is then directed from the hydrocyclone into a diffusion column, and subsequently to a pressure chamber in order to collect non-adsorbed gas. The collected non-adsorbed gas is then recycled back into the evacuated area of the vortex stream. Pressurized gas is added to the system as the gas is adsorbed and dissolved into the liquid.
