More Information
Summary:In the venting of waste gases, particularly where there has been wet scrubbing of the vent gases, there can be a high moisture content which will cause an objectionable visible plume of water vapor that observers might incorrectly interpret to be an air polluting material and the present improved system embodies a moisture eliminating procedure which first runs the gas stream through expansion means to lower the stream pressure and effect sufficient cooling that will permit liquid H2O to be separated out of the stream. The cooled gas stream, with reduced water content, is then compressed to ambient pressure conditions and to a higher temperature such that that may be venting to the atmosphere with little or no plume. Preferably, turboexpander means is used to provide at least a part of the energy for recompressing the stream prior to its discharge to the atmosphere.
