    Abstract: The present application relates to a heat recovery apparatus and method. According to the heat recovery apparatus and method, low-level heat sources at a temperature less than 100° C. discharged from industrial settings or various chemical processes, for example, a petrochemicals manufacturing process are not wasted but used to generate steam and the generated steam is used for various processes to reduce an amount of consumed high-temperature steam that is an external heat source to be used for a reactor or distillation column, thereby not only maximizing energy reduction efficiency but also autonomously producing power consumed by a compressor. Also, an evaporation phenomenon of a part of a refrigerant flow which passes through the compressor may be reduced, thereby recovering heat with excellent efficiency.

A thermal energy discharge mechanism transfers thermal energy directly from the MPCM to a device that uses the thermal energy. In a solar energy embodiment, the thermal energy receiver is formed from a material (e.g., polished copper) that has a relatively low absorptivity value and a relatively low emissivity coefficient, which unexpectedly results in the attainment of a highly efficient solar receiver.

Accordingly, if the absorption of heat by the first heat storage material has decreased, the changeover device changes flow of the second heat storage material so that heat may be extracted from the heat afferent medium by the second heat storage medium. Thus, when the heat afferent medium is a refrigerant, it is possible to supercool the refrigerant thereof. Furthermore, since heat is extracted from the heat afferent medium and is accumulated, accordingly it is possible to anticipate effective utilization thereof.

  • Publication number: 20110067839
    Abstract: A system for rejecting heat from equipment using endothermic isomerization. includes a heat exchanger configured to receive an elevated-temperature process fluid and an isomerization compound capable of endothermic isomerization. When the system is in operation, heat from the elevated temperature process fluid is transferred to the isomerization compound and the isomerization compound endothermically isomerizes to a higher energy state form. A vehicle includes an engine and a body. The body houses a catalytic heat exchanger having an output in fluid communication with the engine, a pump for urging an isomerization compound into the heat exchanger, and a heat sink controller for controlling the pump. A method for rejecting heat from equipment using endothermic isomerization includes providing a compound capable of endothermic isomerization and transferring heat from a process fluid to the compound, such that the compound endothermically isomerizes to a higher energy level isomer.

  • Publication number: 20100263832
    Abstract: A system is described for the thermochemical capture of heat energy and the transfer of this energy to a point of use using a cycle decomposing SO3 to SO2 and O2 and the subsequent oxidation of SO2 and O2 to SO3. This system can store this energy in the form of chemical energy by storing liquid SO2. Embodiments are described wherein oxygen is stored by a solid oxygen storage material or removed and added to the process by selective membranes or by electrochemical pumping. In addition, an alternative embodiment uses an electrochemical generator for the direct conversion of SO2 to electrical energy.

  • Patent number: 7727492
    Abstract: An onboard hydrogen storage unit for a hydrogen powered vehicle including one or more hydrogen storage vessels at least partially filled with a hydrogen storage material which stores hydrogen in metal hydride form. During operation of the hydrogen powered vehicle heat is provided to the hydrogen storage material within the one or more hydrogen storage vessels to aid in desorption of hydrogen from the hydrogen storage material. During hydrogen refueling, heat of hydride formation is removed from the hydrogen storage material within the one or more hydrogen storage vessels to aid in absorption of hydrogen into the hydrogen storage material. The heat of hydride formation is removed from the one or more hydrogen storage vessels via a heat transfer fluid circulated and/or cooled by a stream of compressed air.

  • Patent number: 7712605
    Abstract: An elongate gas distributing tube, which extends in a longitudinal direction of a container, is accommodated within the container that constitutes a gas storage container. Discharge ports, through which the gas is discharged, are provided only on a side circumferential wall of the gas distributing tube. Therefore, the discharged gas advances while being directed toward the inner side wall of the container. The gas distributing tube is surrounded by a gas absorbing/adsorbing material. On the other hand, the gas absorbing/adsorbing material is surrounded by a mixture, which is prepared by mixing the gas absorbing/adsorbing material with a heat storage material, such that heat is absorbed by the heat storage material contained therein.

  • Patent number: 7581698
    Abstract: A transportation vehicle includes a fluid tempering arrangement to supply a gaseous and/or liquid, heated and/or cooled, fluid such as water. At least one thermochemical reservoir is in heat exchange relation with a conduit system, having at least one valve and a controller that controls the transfer of heat between the fluid and the thermochemical reservoir to adjust the temperature of the fluid provided to an outlet. Preferably two interconnected thermochemical reservoirs respectively contain hydride-forming metals having different hydrogen sorption-desorption temperatures. By sorption and desorption of hydrogen in the two reservoirs, heat energy produced electrically during low electrical demand can be chemically stored and later released for heating the fluid during high electrical demand.

A shell-and-tube reactor in the system is adapted to circulate a heat medium having a solid point in the range of 50-250° C. to the outside of the reaction tubes and characterized by initiating temperature elevation of the reactor by introducing a gas of a temperature in the range of 100-400° C. to the reaction tubes' side and then circulating the heat medium in a heated state to the outside of the reaction tubes. By introducing a gas of an elevated temperature preparatorily to the reaction tubes, it is made possible to prevent the heat medium after circulation from being solidified again and enable the reactor to be quickly started up.

  • Patent number: 7318520
    Abstract: A container for use in hydrogen transfer includes structural tubular members and perforations for fluid communication with a central passage covered with a film that is selectively permeable to hydrogen, but not to other gases. The tubular member walls comprise a sturdy material to fix the hydride powder, preventing it from shifting within the container. The hydrogen flow, when being absorbed or desorbed by the metal hydride, will pass through the film both as it is absorbed in the hydride material and also after it is desorbed to pass into the central passage. Simultaneously, the tubular member material, acting as a flexible cover or support for the film, retains contaminant gases within the conduit passage, but permits hydrogen to flow therethrough. Alternatively, a flexible conduit may be interspersed within selected ones of the longitudinal structural members, and hydride material may be packed within the springs, which provide for expansion protection.
