A process and a device are described for producing high purity and high temperature steam from non-pure water which may be used in a variety of industrial processes that involve high temperature heat applications. The process and device may be used with technologies that generate steam using a variety of heat sources, such as, for example industrial furnaces, petrochemical plants, and emissions from incinerators. Of particular interest is the application in a thermochemical hydrogen production cycle such as the Cu&#x2014;Cl Cycle. Non-pure water is used as the feedstock in the thermochemical hydrogen production cycle, with no need to adopt additional and conventional water pre-treatment and purification processes. The non-pure water may be selected from brackish water, saline water, seawater, used water, effluent treated water, tailings water, and other forms of water that is generally believed to be unusable as a direct feedstock of industrial processes. The direct usage of this water can significantly reduce water supply costs.

Heat exchanger using non-pure water for steam generation

A system for producing hydrogen gas from water decomposition using a thermochemical CuCl cycle, the improvement comprising the use of an insulated hydrogen production reactor comprising a reaction chamber and a separation chamber; the reaction chamber having a hydrogen chloride gas inlet and a solid copper inlet; one or more levels provided in the reaction chamber, the number of which is dependant on production scale and pressure drop; each level comprising a perforated plate with associated filter media, the perforations of the plate and media being of decreasing size from top to bottom of the reaction chamber, and being sized to permit downward flow of the hydrogen gas and molten CuCl products, as well as the HCL gas reactant, and to prevent entrainment of solid copper in the molten CuCl; the separation chamber being located below the reaction chamber and being of greater cross section than the reaction chamber and comprising a first hydrogen removal and entrained copper removal zone and a second molten CuCl removal zone; removal of the reaction products being controlled so as to substantially decrease the amount of entrained copper in the molten CuCl; and the first zone having outlets for removal of hydrogen gas and entrained copper particles, with the second zone having an outlet for removal of molten CuCl.

Production of hydrogen from water using a thermochemical copper-chlorine cycle

A method of manufacturing heat-sensitive pharmaceutical powder is disclosed. The original pharmaceutical substances are dissolved in a solution or suspended in a suspension, which is sprayed through an atomizing nozzle and frozen in a cold gas phase or liquid nitrogen atomized directly in the spray-freeze chamber or gas jacket at the same time (for cooling purposes). The particles are freeze-dried at roughly atmospheric pressure in a down-stream fluid flow with exit filter thereby to remove moisture entrapped on or inside the frozen particles. The system has applicability for forming other powders.

Powder formation by atmospheric spray-freeze drying

A method of preparing a pharmaceutical composition is described, comprising 1) atomizing a liquid formulation of a therapeutic agent to produce an atomized formulation; 2) freezing said atomized formulation to form solid particles; and 3) drying said solid particles at about atmospheric pressure to produce a powder, wherein said drying is performed in the presence of vibration, internals, mechanical stirring, or a combination thereof. Another method is described, comprising 1) atomizing a liquid formulation of a therapeutic agent to produce an atomized formulation; 2) freezing said atomized formulation to form solid particles; and 3) drying said solid particles to produce a powder; wherein the atomized formulation comprises droplets having an average mean diameter of between about 35&#x3bc; and about 300&#x3bc;, and/or the powder comprises dried particles having an average mean diameter of between about 35&#x3bc; and about 300&#x3bc;. Compositions made by the above methods, and methods of using the compositions, are also described.
