摘要： In order to expand natural gas under high pressure, a turbogenerator (13) is mounted downstream of a heat exchanger (12). Heat is supplied to the heat exchanger (12) by at least one block-type thermal power station (16) having a gas internal combustion engine and a generator. The heat exchanger preheats the gas to be expanded before the gas is supplied to the turbogenerator for expansion. Both the block-type thermal power station (16) and the turbogenerator (13) generate electric energy which is supplied to the electric network (18).

摘要： The present invention relates to a system for depressurisation of high pressure pipeline fluids. The system may provide for net power generation without the pressurised fluid undergoing liquefaction or solidification or unacceptable temperature reduction as a result of a Joule-Thompson process. The system is particularly relevant for depressurising high pressure natural gas pipelines in an energy efficient manner whilst making possible net power generation. The system for depressurisation of a pressurised fluid in a pipeline comprises at least one depressuriser for expanding the fluid in the pipeline to a lower pressure; and a transcritical heat pump for circulating a supercritical fluid, wherein the supercritical fluid undergoes cooling so as to release heat for transmission to the pressurised fluid in the pipeline prior to at least one expansion of said pressurised fluid.

摘要： The invention relates to a gas-distributing station with an energetic installation using the energy of the gas in a main gas pipeline. The basic goal of the invention is to remove the gas pipeline temperature regime limitations, to raise the effectiveness of the energetic installation of the station and provide for its higher security. The goal is achieved due to the fact that the natural gas from the main gas pipeline (6) is fed to a heat-exchange regenerator (5) where it is heated by a return flow of the gas coming from a turbo-expander (1). From the heat-exchange regenerator (5) the gas first comes to a heat-exchange unit (4) where it is heated by the exhaust gas of a gas-turbine engine (3) and then it comes to the turbo-expander (1). In the turbo-expander (1) the gas is expanded with generation of energy transmitted to an electric generator (2) to which is kinematically connected the gas-turbine engine (3) for transferring its generated energy to the electric generator (2). The expanded and partially cooled gas after the turbo-expander (1) comes to the heat-exchange regenerator (5) for preliminary heating of the gas removed from the main gas pipeline and then is dropped to the main gas pipeline after a reducing device (7), having been cooled down to a temperature slightly exceeding that of the gas inside the main gas pipeline (6).

摘要： The invention is applicable to heating systems for heating pressurized gas, in particular natural gas, which is expanded in an expansion machine. Such heating system comprises an internal combustion engine (14), in particular a gas engine, and a first cooling circuit (11) for removing heat developed by the engine (14), which first cooling circuit (11) incorporates a first heat exchanger (3) for delivering heat obtained in cooling the engine (14) to the gas. According to the invention, such heating system is characterized by a second cooling circuit (20) for cooling combustion air to be fed to the engine (14), which second cooling circuit (20) incorporates a second heat exchanger (7) for delivering heat obtained in cooling the combustion air to the gas. The first cooling circuit (11) can incorporate a separate heat exchanger (15) for cooling the exhaust gases of the internal combustion engine (14) and heating the gas. If the engine (14) is fed by compressed air cooled by an intercooler (21), this intercooler (21) can be incorporated in the second cooling circuit (20). The first heat exchanger (3) can for instance be situated upstream of the expansion machine (5), while the second heat exchanger (7) be situated downstream of the expansion machine (5) or upstream of the first heat exchanger (3). Both the internal combustion engine (14) and the expansion machine (5) can drive one and the same generator (30).
