摘要： The present invention provides an apparatus for desubliming a target compound from a first gas mixture comprising the target compound, comprising: a desublimation means comprising a surface onto which desublimation of the target compound can occur, an inlet through which the first gas mixture can enter the apparatus such that it comes into contact with the surface of the desublimation means, a target compound recovery region, an outlet through which the target compound can leave the target compound recovery region and a cooling means that cools the desublimation means wherein the desublimation means comprises a continuous path that passes through the cooling means and the target compound recovery region and wherein the desublimation means is movable such that the surface continuously circulates between the cooling means and the target compound recovery region, along the path.

摘要： Systems and methods are described for re-moving solidifiable gas from a process gas stream by direct contact with a cold liquid. The process gas stream includes at least gas that is frozen by the cold liquid while one or more other gases of the process gas stream remain in a gaseous state. The process gas stream may include water, and will have a different composition than the cold liquid. The contacting of the cold liquid with the process gas stream may be at a pressure that is less than 200 psia, and optionally less than 100 psia, 50 psia, or even 30 psia, and the solidified gas may be removed from the contacting assembly as a slurry with cold liquid.

摘要： A process to prevent fouling using a desublimating heat exchanger is disclosed. An outlet stream from the desublimating heat exchanger may be split into a plurality of parallel streams. The parallel streams may be sent through other devices for performing a unit operation, and the devices for performing a unit operation may change the temperature of at least one of the parallel streams. Parallel streams of differing temperature may emerge from the devices for performing a unit operation. The parallel streams of differing temperature may be sent to a mixing chamber. A mixed stream of uniform temperature may emerge from the mixing chamber, and the mixed stream may be recycled back to the desublimating heat exchanger. The mixing chamber may be separate from the desublimating heat exchanger, or the parallel streams of differing temperature may be mixed in the desublimating heat exchanger.

摘要： Condensable metal halide materials, such as but not limited to tungsten chloride (WCl6), can be used to deposit metal films 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-WCl6 and 5% by weight or less of the α-WCl6 as measured by X-ray diffraction.
