Abstract
A jet pump or ejector employing steam as the motive fluid is used to produce a dispersion of fog-like liquid droplets containing a reactive chemical in a gas stream. A solution of the reactive chemical is metered to the suction side of the ejector which discharges into the gas stream. Temperature and relative humidity of the gas stream are maintained at levels whereat the ejector discharge condenses to form very tiny liquid droplets containing the reactive chemical.
Claims16
A process for forming a fog-like dispersion of reagent-containing aqueous microdroplets in a gas stream which comprises:
- supplying steam as the motive gas to an ejector, said ejector adapted to accept a liquid suction stream;
- supplying an aqueous solution of a chemical reagent to the suction inlet of said ejector;
- evaporating said aqueous solution within said ejector to form a mixture of reagent and steam;
- discharging said mixture of reagent and steam from said ejector into a gas stream, and
- maintaining the temperature and relative humidity of said gas stream at levels whereat said ejector discharge condenses to form a dispersion of very finely divided, reagent-containing liquid droplets in said gas stream.
