ABSTRACT:
A method and system for converting thermal energy into mechanical energy and producing a flow of pressurized gas in a closed loop with a gas pressurizing unit, a heat storage unit, a cooling unit and a gas absorption unit. The gas pressurizing unit includes a tank in which a mother liquor such as a mixture of ammonia and water is vaporized to produce the pressurized gas flow. The pressure in the tank pumps the mother liquor up against gravity through a second heat storage tank which is part of the heat storage unit and to the cooling unit where the liquor is injected into a third cooled tank forming a part thereof. From the third tank the liquor flows through a microporous tube in a fourth tank forming part of the gas absorption unit where the liquor absorbs spent gas which is supplied thereto. A one way check valve between the fourth and second tanks permits the mother liquor in the fourth tank to flow by gravity, via the second tank where it is preheated, back into the first tank when the pressure in the first tank drops below a preset value and the above cycle is repeated.
