  • Patent number: 11906224
    Abstract: Disclosed techniques include enabling controlled refrigeration and liquefaction and energy management. A liquid is pumped into a closed chamber to compress a vapor. Pressure is increased in the closed chamber by pumping additional liquid into the closed chamber. The increasing pressure enables assimilation of the vapor into the liquid. The heat of compression is removed from the vapor simultaneously with compression. The liquid containing the vapor that was assimilated is withdrawn from the chamber. It is flashed to release at least a portion of the vapor that was assimilated. The flashing results in absorbing a latent heat of vaporization from surfaces in thermal contact with the liquid. A first and second heating/cooling circuit are controlled. Gas within the first heating/cooling circuit is cooled and compressed using a liquid piston. A gas is warmed within the second heating/cooling circuit, and expansion is accomplished using a liquid piston.

  • Patent number: 11906247
    Abstract: A reformer furnace having a reaction space formed with reaction tubes, a firing space fitted with burners and a flue gas channel in fluid connection with the firing space. The burners are arranged at a first end face of the reformer furnace and produce flames oriented towards a second end face to fire the reaction tubes. The flue gas channel has a transition region and a withdrawal region, wherein the flue gas channel is connected to the second end face of the firing space via the transition region and the transition region of the flue gas channel has a reduced channel diameter compared to the withdrawal region of the flue gas channel. The transition region has a constriction relative to the withdrawal region which results in a hydraulic decoupling between the firing space and the withdrawal region of the flue gas channel.

  • Patent number: 11906248
    Abstract: A method of heating a fluid stream for a power plant comprises diverting a portion of a main flow of flue gas from a power plant at a first pressure (P1), flowing the diverted flue gas through a heat exchanger, flowing an auxiliary fluid stream through the heat exchanger, and transferring heat from the diverted flue gas into the auxiliary fluid stream in the heat exchanger to raise a temperature of the auxiliary fluid stream from a first temperature (T3) to a second temperature (T4), while lowering a first temperature of the diverted flue gas (T1) to a second temperature (T2). The diverted flue gas is then returned to the main flow of flue gas in the power plant at a second pressure (P2). The method of flue gas flow through the heat exchanger may be accomplished by adding a self-contained flow path from a boiler higher pressure (P1) zone to a lower pressure (P2) zone.
