Abstract: A method and apparatus for simultaneously removing alkali chlorides from an industrial process and purifying vaporizable contaminants such as mercury from a particulate material. Gases containing alkali chlorides are cooled to a temperature above the boiling point of the contaminants and below the boiling point of the alkali chlorides. Particulates rich in alkali chlorides are removed from the gas stream with a first dust collector. The gas stream cleaned of alkali chlorides is directed to a reaction area where particulate material containing mercury contaminants is inserted into the gas stream to vaporize the contaminants from the material and entrain the cleaned material in the gases. The gases are directed to a second dust collector to remove the entrained particulate material, after which a sorbent or chemical reagent is injected in the gases to interact with the contaminants and form a contaminant containing product that is entrained in the gases and thereafter separated from the gases.

Abstract: A jacket material into which a gas adsorbing device and core material are inserted is decompressed in a vacuum chamber, the opening is sealed, and then the jacket material is exposed to the atmosphere. In the atmospheric pressure, a pressure of about 1 atm which is equivalent to the pressure difference between the inside and outside is applied to the jacket material of the heat insulator. The jacket material is made of a plastic laminated film and is deformed by pressure. A protruding portion is plunged into a container to drill through holes, and a gas adsorbent in the container communicates with the inside of the jacket material. Thus, both during holding and in applying to the vacuum heat insulator, the gas adsorbent can be applied to the vacuum heat insulator without degradation, and the high degree of vacuum can be kept for a long time.

Abstract: An improved structure of cooling tower includes a fan housing with a fan disposed therein, induction openings distributed on the fan housing and located below the fan, and a diffuser stack disposed at one end surface of the fan housing. In operation, cold air is drawn into the cooling tower by the fan through inlet openings of the cooling tower so as to exchange heat with the condensing water within a water chiller. When warm and wet air is drawn out of the cooling tower and the warm and wet air outside the cooling tower is induced in through the induction openings and then is drawn out, circulation reflux of warm and wet air, which tends to occur in conventional cooling towers, can be avoided and therefore increase the efficiency of the water chiller.

Abstract: A differential absorption spectrum for a reactive gas in a gas mixture can be generated for sample absorption data by subtracting background absorption data set from the sample absorption data. The background absorption data can be characteristic of absorption characteristics of the background composition in a laser light scan range that includes a target wavelength. The differential absorption spectrum can be converted to a measured concentration of the reactive gas using calibration data. A determination can be made whether the background composition has substantially changed relative to the background absorption data, and new background absorption data can be used if the background composition has substantially changed. Related systems, apparatus, methods, and/or articles are also described.
