Abstract
An assembly for producing wet compression of gas being compressed in a centrifugal-type, multistage gas compressor having an impeller, a diffuser 'downstream' of the impeller, and a cross-over channel connected to the downstream end of the diffuser includes a plurality of liquid jets for injecting a vaporizable liquid such as water into a gas stream undergoing compression. The liquid jets are positioned axisymmetrically about the longitudinal axis of the compressor shaft and are adapted to inject liquid into the diffuser substantially upstream of the cross-over channel, and, in a preferred embodiment, have a radial spacing from such axis of about 1.05 to 1.1 times the maximum radius of the compressor impeller. The invention attains a marked increase in vaporization of the injected liquid, providing better compressor performance and reduced wear of compressor internal parts.
