Abstract: An engine includes a radial arrangement of cylinders each having a reciprocating piston with a piston head and a connecting rod pivotally linked to the piston head at an upper end. A lower end of each connecting rod is pivotally linked to a crank disk that is rotatably mounted on a crank arm of a crankshaft. Steam intake valves at each cylinder are momentarily opened by a bearing cam roller that is moved in a circular path by rotation of the crank disk to sequentially engage spring urged cam followers on inboard ends of radially extending valve stems. Low pressure steam or gas is injected into the top of each cylinder, as the intake valves of the cylinders are opened in sequence, thereby forcing the piston in each cylinder through a power stroke to move the crank disk and turn the crankshaft. Angular displacement of each connecting rod through the return stroke of the piston urges an exhaust reed valve on the piston head to an open position, thereby releasing exhaust steam to a condenser chamber.

Abstract: Turbine exhaust steam, axially fed between counter-rotating radial flow disk turbines, separates into: (1) a radially inward flow of low enthalpy dry steam, and (2) a radially outward flow of high enthalpy steam, noncondensibles, and condensate. The radially inward flow goes to a conventional condenser. The radially outward flow loses enthalpy turning the disk turbines as it passes in the boundary layers against the disks, thus becoming low enthalpy dry steam, and the counter-rotation of the disks by impinging mass flow of condensate, high enthalpy steam, and noncondensibles sustains a cascade of dynamic vortex tubes in the shear layer between the boundary layers. The low enthalpy dry steam resulting from work being done flows into the condenser through the vortex cores of fractal turbulence. Condensate exits the periphery of the workspace, ready to be pumped back into the Rankine cycle.

Abstract: A hermetic Rankine cycle in a sealed casing powers an internal centrifugal condensate pump with an internal vapor turbine during forced convective heat transfer between a heat source and a heat sink. No work is imported into the cycle during operation. A centrifugal pumping disk shears the working fluid against a heating surface, sweeping evolving vapor into radial vortices which provide sink flow conduits to a vapor space at the center of the cylindrical turbine. Convective mass flow through the vapor space to the condensing end of the casing spins the turbine and the centrifugal pumping disk which is connected to it. Vapor is continuously swept from the heating surface, so bubbles do not form and superheat while blocking heat flux into liquid working fluid. Vapor is sucked through the radial vortices into the central vapor space and into the condensing end of the casing along the low pressure gradients in vortex cores established by cooling power.

For this purpose, a vapor is supplied to the desorption process, the vapor is injected into the charged absorption medium, wherein the condensation heat released by the condensation of the vapor is transferred to the charged absorption medium, and the partial pressure of the carbon dioxide is simultaneously reduced in the desorption unit.
