摘要:
Condensable metal halide materials, such as but not limited to tungsten chloride (WCl 6 ), can be used deposit films metal or metal containing films in a chemical vapor deposition (CVD) or atomic layer deposition process. Described herein are high purity compositions comprising condensable materials and methods to purify condensable materials. In one aspect, there is provided a composition comprising: tungsten hexachloride which is substantially free of at least one impurity and wherein the tungsten hexachloride comprises at least 90%, preferably 95 % and more preferably 99 % by weight or greater of a β- WCl 6 and 5% by weight or less of the α- WCl 6 as measured by X-ray diffraction.
摘要:
A method for cleaning a contaminated solvent used to treat a gas stream, for example a contaminated glycol or a contaminated amine stream, by vacuum evaporation using a mechanically-maintained horizontally-orientated thin film evaporator, where the contaminant material is recovered from the thin film in solvent-free form, as either a heavy organic material or as free flowing salts.
摘要:
Distillation apparatus comprises a condensing chamber and a heating chamber arranged on an enclosure. Liquid feed into the condensing chamber is pre-heated and flows to the heating chamber where it is boiled to produce vapor. Gas sparging in the condensing chamber enhances heat transfer and absorbs additional vapor generated by pre-heating. The condenser is a helical or other horizontal tube heat exchanger.

摘要:
An evaporation device has an inner tube and an outer tube. The inner tube is made of a hydrophilic membrane, such as DutyionT. The outer tube is preferably made of a material that readily absorbs solar radiation and is a good heat conductor. There is a gap between the inner tube and the outer tube for the flow of air. The inner tube contains a flow of impure water. The hydrophilic membrane allows water to pass to the outside of the inner tube as vapor, but prevents impurities from passing through. Air flowing in the gap takes up the water vapor and humidified air exits the evaporation device. This humidified air is subsequently cooled to collect the vapor and provide purified water, e.g. at a condenser.
摘要:
Device, system and operation method to perform functions in a semiautomatic manner, which permits the most favorable condition to evaporate a plurality of environmental samples that are diluted in solvents, by means of gas sweeping, preferably nitrogen, and a control electronic system that permits the superficial evaporation of the solvent thanks to exposing a cold sample kept at a constant temperature to a controlled gas flux. Furthermore, safety measures are considered to protect the extract, such as: acoustic and luminous signals that inform when it has been reached a critical moment in the process, reduction of gas flux during the last stage of the evaporation and valves to completely shut off the gas flux if a determined time period is exceeded.
摘要:
A process, and a device for implementing the process, for separation of fluids in emulsion and/or in solution, and/or for low pressure distillation, in particular of water and/or gaseous hydrocarbons dissolved in crude petroleum, and/or for separation of crude petroleum droplets emulsified in water, so as to obtain water with the necessary characteristics for its injection without pollution of underground aquifers, and/or when the mixture is dominant in crude petroleum, acceleration of the settling of the water in the lower part of the mixture, and/or for low pressure distillation of crude petroleum. The method creates a localized zone (5) of reduced pressure on part of the free surface of a liquid (2) to be processed, within a closed processing tank (1), without the overall pressure inside the closed processing tank being affected.
摘要:
Die Erfindung betrifft eine Vorrichtung und ein Verfahren zur Luftbefeuchtung in Gebäuden mit transparenten Oberflächen mit den Zielsetzungen der Raumkühlung durch steuerbare Beschattung und Wasserverdunstung bei gleichzeitiger Überführung der durch die Wasserverdunstung zwischengespeicherten Energie zu einem Wärmetauscher. Dabei wird der höhere Energiegehalt der feuchten Luft zur Verringerung der Lüftungsleistung genutzt und durch Kondensation des vorverdunsteten Wassers am Wärmetauscher der Wärmeübergang verbessert. Die Anlage ermöglicht die Aufbereitung von Wasser durch Destillation bei Verdunstung von salzhaltigem oder verunreinigtem Wasser und anschließender Kondensation.
