Abstract

A method of mixing a gas and a vaporizable liquid to provide a gaseous mixture having a constant composition, regardless of change in rate of flow, except as hereinafter provided, comprising: PA1 (a) introducing a mixture comprising a gas and a vaporizable liquid in predetermined proportions into the tube side of a tube and shell heat exchanger at a flow rate sufficient to cause turbulent flow; PA1 (b) introducing a heating fluid into the shell side of the heat exchanger at a temperature sufficient to vaporize at least part of the vaporizable liquid whereby the vaporizable liquid separates into a vapor phase and a liquid phase; and PA1 (c) delivering the mixture of gas and vapor phase to a use point and recycling the liquid phase to a point at which it will be mixed with gas for introduction into step (a).
