A novel Rankine cycle system configured to convert waste heat into mechanical and/or electrical energy is provided. In one aspect, the system provided by the present invention comprises a novel configuration of the components of a conventional Rankine cycle system; conduits, ducts, heaters, expanders, heat exchangers, condensers and pumps to provide more efficient energy recovery from a waste heat source. In one aspect, the Rankine cycle system is configured such that an initial waste heat-containing stream (16) is employed to vaporize a first working fluid stream (20), and a resultant heat depleted waste heat-containing stream (17) is employed to aid in the production of a second vaporized working fluid stream (25). The Rankine cycle system is adapted for the use of supercritical carbon dioxide as the working fluid.

A multi-stage, two-flow, axial flow expander close-coupled to a driven machine, such as a generator. The expander includes one or more expansion stages separated by a series of flow stream dividers that separate each expansion stage into outer and inner expander flowpaths. Working fluid at a first temperature is directed into the outer expander flowpath for expansion, and working fluid at a second, lesser temperature is directed into the inner expander flowpath for expansion. Expansion of the working fluid drives the driven machine.

Power plant, in which the steam is heated by the heat released by the compressed air. After it has actuated the steam engine, its heat is recuperated in order to heat the condensation water. The kinetic energy of the compressed air actuates the pneumatic motor coupled to the compressor, to the steam engine and to the starter.
摘要:
A method for separation of CO 2 from the combustion gas from a thermal power plant fired with fossil fuel, wherein the combustion gas from the thermal power plant is used as cooled, compressed and reheated by combustion of natural gas in a combustion chamber to form an exhaust gas, where the exhaust gas is cooled an brought in contact with an absorbent absorbing CO 2 from the exhaust gas to form a low CO 2 stream and an absorbent with absorbed CO 2 , and where the low CO 2 stream is heated by means of heat exchanges against the hot exhaust gas leaving the combustion chamber before it is expanded in turbines, is described. A plant for performing the method and a combined plant is also described.
摘要:
The invention pertains to an apparatus and a process of generating work comprising the steps of expanding a gas, preferably substantially adiabatically and/or at the critical pressure and temperature of the gas, causing part of the gas to condensate and form a liquid phase, and separating, during or after expansion, at least part of the liquid phase from the gas phase. This process facilitates generating work at a relatively high efficiency.
