A simple and effective system for dispersing a gas into a liquid to carry out chemical and biochemical reactions in the presence or absence of solid particles
The proposed system is a vertical liquid jet issuing from an orifice near the surface of a gas-liquid mixture. The jet sucks gas, then penetrates into a coaxial pipe until it hits a horizontal impact plate and disperses into the gas-liquid mixture. The coaxial tube has holes in its upper part to recycle the mixture. The performances of this gas-liquid contacting device are very good. Experimental relations are given and possible applications are examined. One example of reactor calculation is given.
