An electric power generating system includes an autoclave coupled to a natural gas source, an oxygen source, and having a pressure reducing outlet valve. A high-pressure pump provides a solution of ammonium hydroxide and ammonium carbonate solution under pressure to the autoclave. An exothermic reaction generates high-pressure steam for electrical power generation. A crystallizer receives ammonium carbonate from the reaction for the formation of crystallized ammonium carbonate fertilizer.

A system for the generation of mechanical or electrical energy from heat energy, where increasing a height or pressure in a liquid chamber of the system containing a liquid increases an efficiency of the system up to a hundred percent or increases such efficiency until a critical temperature or pressure of the vapor (gas) is reached at the bottom of liquid chamber or in the boiler of the system depending upon the increment in height, pressure and the type of liquid used in the system. An increase in height of the system for such increased efficiency can be adjusted to a smaller height by maintaining a series of liquid and gas chambers where the vapor flows through the series of chambers or by adding pressure valves. The heat energy from high to low temperature sources can be convened to mechanical and electrical energy.

The invention discloses a method for converting thermal energy into mechanical energy, and/or for cooling, comprising the steps of at least partly evaporating a working fluid, expanding said evaporated working fluid, absorbing said expanded working fluid into a liquid absorption mixture, at least partly extracting the absorption mixture from the absorber, pressurizing said extracted absorption mixture, separating said pressurized absorption mixture into a working effluent and an absorption effluent, and feeding said working and absorption effluent to the evaporator and absorber respectively. In particular, during said separation, the absorption mixture is subjected to a pressure at or above the condensation pressure of the substantially pure working fluid, and/or to a temperature at or below the condensation temperature of the substantially pure working fluid. The invention further discloses a closed-cycle absorption system, preferably suitable for performing the method.

Embodiments of the invention involve the application of a disk-in-tube type of wet or dry ESP (electrostatic precipitation) technology for the capture/removal of airborne particles entering a gas turbine compressor. This provides an effective method of particulate removal without the inefficiencies associated with conventional filtering techniques. Embodiments of the innovative approach also eliminate the inlet airstream blocking effect of a conventional filter, thus making its use and operation adaptable to different operating environments and processes that require clean input air streams (including industrial manufacturing processes, power generators, combined turbine and fluid recapture systems for use in heating and cooling, etc.).

A method and system enabling the efficient use of thermal energy to provide kinetic energy and/or electrical energy. The method uses at least two heat exchangers for heating the working medium, a heat engine and a condenser. The working medium consists of at least two substances. The working medium is partially condensed on the primary side of the first heat exchanger, wherein heat is transferred to the working medium flowing on the secondary side and, subsequently, further condensation heat is transferred to a cooling circuit in a condensation heat exchanger on the primary side of the condensation heat exchanger. Subsequently, the working medium is redirected to the secondary side of the first heat exchanger. A separation of gaseous fractions of the working medium takes place in the condensation heat exchanger on the primary side.

A method for generating electricity and cold and a device for realizing same, consists in a closed absorption cycle in which a working body is a mixture of a low-boiling (refrigerant) component and a high-boiling (absorbent) component. The method involves evaporating a strong solution in a steam generator, thus forming a refrigerant vapor and a weak solution, expanding the refrigerant vapor in a turbine, thus producing work, and, after the turbine, absorbing spent vapor in an absorber, forming a strong solution. A distinguishing feature of the method consists in changing the concentration of a strong solution using two stages, including not only evaporation but also filtration. The proposed method and device allow for significantly increasing the efficiency of systems for generating electricity relative to analogous known methods.
