Abstract: An exhaust gas plume mitigation process and system includes either mixing secondary heat into a moisture rich exhaust gas stream, or diverting a moisture rich exhaust gas stream into a primary exhaust stack having hot exhaust gases flowing therethrough. Moisture rich exhaust gas from a liquid concentrator may be diverted into a high temperature exhaust stack of an engine, a generator, or a flare. The high temperature exhaust gases from the engine, the generator, or the flare raise the temperature of the moisture rich exhaust gas from the concentrator. The high temperature exhaust gases from the engine, the generator, or the flare are also lower in moisture content, so that the moisture rich exhaust gas from the concentrator is diluted by the drier high temperature exhaust gas. As a result, the mixed gas is less likely to develop a moisture plume upon exit to the atmosphere.

Abstract: An X-ray analysis system controls the humidity of a sample. The analysis system has a device for dividing a gas flow stream into two portions and for submerging a membrane humidifier tube, containing one of the gas flows, in a water bath in which the gas passing through that tube is moisturized to a desired degree. The two gas flows are subsequently reunited at a controlled temperature to provide for combined moisturized gas at a desired temperature and humidity. The gas is then sprayed onto the sample and an excess moisturized gas vented from the chamber to maintain a moisturize gas sample without condensation of water on or near the sample. This system and a method for its use allow measurements of samples to be made as a function of humidity and temperature over wide ranges of these parameters under highly stable conditions in a straightforward manner which are not susceptible to malfunction and which can be produced and operated at low cost.

Abstract: An inactive gas is introduced into an organic material evaporation source to place a thin organic film material in the organic material evaporation source in an atmosphere having a relatively high pressure, and the temperature of the thin organic film material is increased up to a certain temperature. Then, the organic material evaporation source is evacuated to lower the pressure around the thin organic film material for thereby causing the thin organic film material to emit a vapor. Since no wasteful vapor is emitted from the thin organic film material, the thin organic film material is effectively utilized. Because the inactive gas acts as a heating medium, the temperature of the thin organic film material is increased at a high rate, and the thin organic film material is uniformly heated. When the temperature of the thin organic film material is lowered in an inactive gas atmosphere, it can be lowered at a high rate.

Abstract: Air contaminated with combustible dust particles is removed and subjected to a high density air scrubber which safely removes the fine combustible dust particles from the contaminated air. The resulting water saturated, cleansed air is mixed with a continuously regulated amount of drier outside air until a desired absolute humidity is achieved, the regulation being responsive to the relative humidity changes within a work area in which the humidity is to be controlled. The air mixture is then conveyed into the work area which imparts a known temperature rise thereto. The temperature rise lowers the relative humidity of the air mixture to the desired level.
