21. The amount of air mixed with the gas stream affects the completeness of the combustion reaction. 22. The metal is vaporized in a vacuum chamber and then supercooled with an inert gas stream . 23. These facilities straddled gas pipelines to extract additional volumes of gas liquids from the gas stream . 24. Low temperatures obtainable from the expansion of these high-pressure gas streams are utilized to a profitable advantage. 25. These gas streams are usually produced by processes requiring ventilation, including paint booths, printing, and paper mills. 26. The plant separates methanol ( used for hydrate inhibition ), water and condensate from the gas stream . 27. The entrained suction fluid may be a gas, a liquid, a slurry, or a dust-laden gas stream . 28. Alternatively, the gas stream may consist of air or another ( sometimes inert ) gas that is preheated. 29. Gasification is the conversion of carbon rich material through high temperature with partial oxidation into a gas stream . 30. Therefore, the rapping system must be designed and adjusted to minimize re-entrainment of particles into the gas stream .
