Title: Countercurrent flow absorber and desorber

Abstract

Countercurrent flow absorber and desorber devices are provided for use in absorption cycle refrigeration systems and thermal boosting systems. The devices have increased residence time and surface area resulting in improved heat and mass transfer characteristics. The apparatuses may be incorporated into open cycle thermal boosting systems in which steam serves both as the refrigerant vapor which is supplied to the absorber section and as the supply of heat to drive the desorber section of the system. 9 figs.

  • Countercurrent flow absorber and desorber devices are provided for use in absorption cycle refrigeration systems and thermal boosting systems. The devices have increased residence time and surface area resulting in improved heat and mass transfer characteristics. The apparatuses may be incorporated into open cycle thermal boosting systems in which steam serves both as the refrigerant vapor which is supplied to the absorber section and as the supply of heat to drive the desorber section of the system.
  • A process and apparatus are claimed for production of liquid and gaseous hydrocarbon products from solid organic carbonaceous materials by reacting free falling solids with a countercurrent hydrogen-containing gas stream. The process is conducted with a lean solids phase which provides good process control and uniform flow of solids even in the presence of condensation and refluxing of liquids on the solid particles. Oil shales of the Eocene period having Modified Fischer Assays of less than about 9 gallons of oil per ton and representing less than half the organic carbon present in the oil shale are particularly well suitedmore » for the process of this invention. A reactor particularly suited for conducting reactions between free falling solids and countercurrent flowing gas streams is disclosed together with preferred methods for introduction of solid feeds to the top of the reactor including distribution baffles and fluidized bed feed distribution systems.« less
  • Afterburner apparatus for receiving from an incinerator products of combustion and distributing them through a domed distributor in counterflow manner throughout a housing, in opposition to a stream of combustible gas.
  • A plant for rapid liquid-liquid extraction by the countercurrent flow process is designed which comprises a number of stages arranged in a cascade. Each stage comprises successively an ejector nozzle which mixes the phases and injects them into a cyclone, if necessary a coalescence tube fitted at the upstream end of the cyclone, a cyclone for separating the phases, and means for extracting energy from one or both of the liquids to operate the ejector nozzles. An example of the utilization of the plant is given using a uranyl nitrate solution and a solution of TBP in dodecane. (D.L.C.)
  • Chevron Research Co.'s improved variation of a CO/sub 2/-acceptor coal-gasification system results in a much greater throughput capacity for a given reactor size while retaining the salient advantages of the basic process. In the disclosed design, the hot calcined CO/sub 2/-acceptor solid contracts the coal particles in countercurrent plug-like flow in the gasifier. The acceptor flows downward in a fluidized state while the entrained coal flows upward. The gasification heat is provided by the sensible-heat transfer from the hot (1850/sup 0/F) acceptor to the coal and by the exothermic reaction that occurs between the CO/sub 2/ and the CO/sub 2/more » acceptor.« less
