Abstract: A filter system for an absorption chiller includes a replaceable filter element, a plateable member, and a sacrificial member. The filter receives a weak solution from the chiller's evaporator, receives a stronger solution from the chiller's absorber, and discharges a mixture of the solutions to the chiller's generator. Conveying the weak solution to the filter system avoids creating an accumulation of lithium bromide in the evaporator and helps dissolve or flush inhibitors from the filter element on a continuous basis. Combining the weak and stronger solutions in the filter system attempts to confine a corrosion or copper oxide plating process to an area of the chiller that can be readily serviced. The plateable member and the sacrificial member provide replaceable or consumable members used in the corrosion or plating process.

The thermally conductive matrix (62, 64) is a copper metal matrix or carbon/graphite matrix, and the solid cryogen reservoir (18) is a beryllium reservoir (18).

Abstract: A liquefaction system includes a source tank containing a supply of liquid nitrogen with a head space there above filled with nitrogen vapor. A pump transfers the liquid nitrogen to a heat exchanger. The heat exchanger also receives natural gas that has been processed in a purifier. The natural gas is liquefied by free cold from the liquid nitrogen so that liquid natural gas (LNG) is produced. The LNG travels to an LNG destination tank for storage and/or transport. The liquid nitrogen is vaporized in the heat exchanger. The resulting nitrogen gas is directed to a process system that may include, for example, cylinders for welding or other applications. Between liquefaction cycles, the purifier is regenerated by a vacuum and nitrogen vapor from the head space of the source tank. Steel shot is mixed with absorbent in the purifier so that the absorbent is cooled for increased performance.

An amount of R32 for filling the refrigerant circuit is set to be in a range of 120 g to 450 g per kW of refrigerating capacity, or an amount of R32 for filling the refrigerant circuit is set to be in a range of 400 g to 750 g per liter of unobstructed capacity of the condenser (22). By using R32 as a refrigerant that is small in Global Warming Potential (GWP), an energy-saving refrigeration against global warming with high coefficient of performance (COP) is obtained.

Abstract: In the method for producing a particulate material (58) from an at least partially liquid material (35) containing a solvent and/or dispersant, this material (35) is atomized in a process chamber (21) into droplets which are frozen to particles (131) by contact with a freezing fluid. The particles (131) are then dried by freeze-drying in the or in another process chamber (22) having a filter (18) at the top. For the freeze-drying, cooled process gas is passed upward from below through the process chamber (22) and through the filter (18) in such a way that at least a substantial part of the particles (131) rest against the filter (18) at least for a substantial part of the freeze-drying taking place in the process chamber (22). This makes it possible to dry a batch of particles (131) in a short time.

Abstract: An automated cold storage apparatus, and related method thereof, provides a sample process management system that is a revolutionary approach to the storage and retrieval regarding critical samples. The system—a significant technological breakthrough in laboratory automation—is the first ultra low temperature robotic system capable of being validated. Samples in containers are stored and retrieved robotically through an airlock climate-control chamber that is automatically dehumidified by a dry gas purge, such as a carbon dioxide or nitrogen purge or the like. This purge rapidly reduces ambient humidity to a desirable relative humidity (RH), e.g., less than about 15% RH, virtually eliminating the accumulation of frost. Microplates are systematically identified using barcode technology, for example. Once through the climate-controlled chamber, the containers (i.e., samples) are robotically transferred to the rotary mechanism.
