  • Patent number: 8555642
    Abstract: A method of utilizing waste heat to create a pressurized working fluid is disclosed. The method includes providing a vessel containing a sorbent system, introducing a feed of waste heat to a heat exchanger external to the vessel to heat a feed of working fluid, introducing the heated working fluid from the heat exchanger to the vessel to obtain pressurized working fluid, and directing the pressurized working fluid from the vessel to a work component. The method is particularly suited to make use of waste heat an industrial process, (e.g., a chemical processing or petrochemical refining operation) in which low grade heat source(s) are used to drive the sorption system.

  • Publication number: 20110232305
    Abstract: The present application provides a sorption system for generating power and chilling that includes at least one absorber to absorb a working fluid in a liquid sorbent, a pump in fluid communication with the absorber to yield a feed of pressurized liquid sorbent and absorbed working fluid, a heat source to heat the feed of pressurized liquid sorbent and absorbed working fluid to yield a feed of working fluid at a supercritical state, a generator in fluid communication with the feed of working fluid at a supercritical state to yield power and a feed of working fluid in an at least partially condensed state, and an evaporator in fluid communication with the feed of working fluid in the at least partially condensed state to yield chilling and uncondensed working fluid. Additional systems and method for the generating power and chilling are provided.

  • Publication number: 20110219802
    Abstract: The present invention relates to process modifications and apparatus designs that are conducive towards minimizing temperature swings (?T) useful to yield operating pressures that provide work and/or refrigeration (e.g., electricity and/or refrigeration) in sorption systems. Such process modifications and designs are particularly suited to make use of waste heat an industrial process, (e.g., a chemical processing or petrochemical refining operation) in which low grade heat source(s) are used to drive the sorption system.
