Abstract

Enthalpy is recovered as work from hot industrial effluents by the controlled expansion of liquids through convergent-divergent nozzles in true reaction turbines. For hot liquid effluents, the effluent itself serves as the working fluid. For gaseous effluents, a high boiling stable liquid is heated by the gas in a scrubbing tower and then the liquid is expanded as the work fluid. If the effluents contain undesirable levels of particulate pollutants, the liquid is cleaned before it is expanded. This paper reports the results predicted when using both impulse and true reaction turbines. Results predicted when using work fluids as glycerol, tricresyl phosphate, bi-phenyls, and silicone oils are presented. Cycle efficiencies as high as 26% are predicted as possible. Recoveries as high as 30MW seem possible when using the approach as a bottoming cycle for a 460 MW steam-electric utility discharging flue gases at 500F.

Recovery of enthalpy from hot industrial effluents

Patent Molini, A; Zener, C

Pollutants are removed from a hot industrial effluent after which enthalpy is recovered from the hot effluent by converting a working fluid into a foam in a flashing unit and using the foam to propel a turbine. For liquid effluents the effluent itself serves as the working fluid. For gaseous effluents the scrubbing fluid used to remove pollutants is used as the working fluid.
Recovery of enthalpy from hot fluids

Patent Molini, A; Zener, C

Enthalpy is recovered from hot industrial effluents by converting a working fluid into a foam in a flashing unit and using the foam to propel a turbine located within or at the output of the flashing unit. For liquid effluents the effluent itself serves as the working fluid. For gaseous effluents a liquid is heated by the gas and then the liquid is used as the working fluid. If the effluents contain undesirable levels of pollutants working fluid is cleaned before it is flashed. The specification discloses both impulse and reactive turbines which the foam can propel.
Bladeless turbines: a geothermal prime-mover and re-injection pump

Journal Article Possell, C - Geotherm. Energy Mag., v. 1, no. 1, pp. 20-21

The success of economically converting geothermal energy depends upon the solution to the problem of handling a two-phase effluent of steam and hot brine for recovery of energy. The effluents contain high percentages of superheated water and dissolved solids. More costly closed or binary cycle systems that utilize some form of heat exchange system with attendant penalties in system efficiency and deposition problems are necessary. The new bladeless turbine developed by U. S. Federal Engineering and Manufucturing, Inc., of San Diego discards conventional impulse and reaction design principles in favor of boundary layer drag'' to accomplish the energy conversion frommore »« less
Work from steam expanded to low quality levels

Technical Report Molini, A

To improve the efficiency of steam engines, designers resorted to larger temperature differences between the heat source and the heat sink. A high temperature of approximately 1100 F, limited by the materials of construction, was soon reached. The heat sink is limited by the environment and mechanically to a large extent by the moisture level to which the work-fluid is expanded. Because of the close dimensional tolerances together with the inability to simultaneously remove the condensate, modern steam turbines are restricted to expansion cycles from super-heat to steam qualities of approximately 95%. Large losses of efficiency are experienced when expandingmore »« less
Enthalpy restoration in geothermal energy processing system

Patent Matthews, H

A geothermal deep well energy extraction system is provided of the general type in which solute-bearing hot water is pumped to the earth's surface from a relatively low temperature geothermal source by transferring thermal energy from the hot water to a working fluid for driving a primary turbine-motor and a primary electrical generator at the earth's surface. The superheated expanded exhaust from the primary turbine motor is conducted to a bubble tank where it bubbles through a layer of sub-cooled working fluid that has been condensed. The superheat and latent heat from the expanded exhaust of the turbine transfers thermalmore »« less
