摘要:
The present invention relates to a gas heating system applicable to a gas in transit between an inlet duct (2) and an outlet duct (3), wherein the pressure of the gas in the inlet duct (2) is higher than the pressure of the gas in the outlet duct (3), comprising thermal power generation means (4; 4') for heating the gas between the inlet duct (2) and the outlet duct (3); and means (14) for controlling the thermal power generation means (4; 4'). Said system comprises means (18) for measuring the flow rate (Qu,gas) of the gas in the outlet duct (3) connected to the means (14) for controlling the thermal power generation means (4; 4'). The invention also concerns a method suitable for achieving said heating of the gas.

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:
In a device for continuously conditioning fed-out natural gas prior to feeding the same to supply lines leading to consumers, comprising a mixing station for producing a burnable gas from natural gas and oxygen, a reactor container for a catalytic combustion of an introduced mixture of burnable gas and natural gas, at least one drying station that is connected downstream of an outlet of the reactor container and has at least one separator, particularly for water, and further comprising at least one expansion fitting for reducing the pressure, it is provided to dispose the reactor container and at least one separator chamber of the separator in an enclosed housing. A mixing chamber, into which a first feed line for fed-out cold natural gas opens, is disposed in the housing between the reactor container and the separator chamber. A transition is provided for the direct entry of the heated natural gas flowing out of the reactor container into the mixing chamber. The mixing chamber comprises a mixing chamber outlet, which leads into the separator chamber. The reactor container, separator chamber and mixing chamber have condensate drains leading into external condensate traps. A second feed line for fed-out natural gas opens into a region of the housing which corresponds to the arrangement of the reactor container in the housing. Expansion fittings are connected upstream of the feed lines for natural gas into the housing.
