Abstract: A water-cooled distilling apparatus for purifying or distilling raw water. The apparatus includes a boiler, cooling tray assembly, and collection vessel. In use, raw water is initially poured into the boiler which has a self-regulating screen in it. As the water beings to boil, the screen rises to float above the raw water. The height of the screen above the water automatically adjusts proportionately to the rate of boil to proportionately expose more or less surface area of the screen. A water film forms on the exposed surface area of the screen and clean steam rises therefrom into the cooling tray assembly where it is deflected into a condensing area on each level of the assembly. In each condensing area, heat is transferred from the steam into coolant water in a reservoir, causing the coolant water to evaporate from the reservoir and the steam to condense on the bottom of the surface of the reservoir. Distillate formed by the condensing steam is then collected and transferred to a collection vessel.

The parer fraction from one effect is conveyed, at a high level, into a subsequent effect in the direction of movement of the liquor, while the dirtier fraction is conveyed, at a high level or at the very top, into a preceding effect in the direction of movement of the liquor.

Steam evolved from the boiler tray is conducted through a first check valve in the cover member to demister chamber when the mist or carryover water in the steam impinges on a baffle and is separated from the steam as condensate.

Abstract: Process and apparatus for reclaiming or concentrating waste aqueous solutions of gas treating chemicals, such as alkanolamines, used for removing acid components or water vapor from natural gas. The process involves heating the waste solution under a high vacuum to form a vapor and a liquid residue. The temperature and vacuum can be varied to form a vapor consisting mainly of water vapor or a vapor containing both water vapor and vaporized gas treating chemical. The vapor is subsequently condensed or passed through a wash column to produce a concentrated solution. The liquid residue is heated by passing it through a single pass, generally co-current heater at a rate which avoids localized overheating of a liquid to a temperature above the decomposition temperature of the gas treating chemical. The heated liquid residue is then used to heat the feed waste solution by being thoroughly mixed with it, thus avoiding overheating of the feed solution.
