摘要： For expanding highly pressurized natural gas, use is made of a turbo generator (13) having a heat exchanger (12) connected at its upstream side. Heat supply to the heat exchanger (12) is performed by at least one block-type thermal power station (16) comprising a gas-fired internal combustion engine and a generator. The heat exchanger preheats the gas to be expanded before the gas is supplied to the turbo generator for expansion. Both the block-type thermal power station (16) and the turbo generator (13) generate electric energy which is fed into the power supply network (18).

摘要： An energy recovery, pressure reducing system according to the present invention for reducing high pressure gas in a transmission pipeline to a lower pressure in a consumer pipeline includes a primary pressure regulator or regulating valve having an adjustable flow control opening, the pressure regulating valve being selectively connectable between the transmission and consumer pipelines for throttling the high pressure gas and producing low pressure gas when the primary pressure regulator or regulating valve connects the pipelines. A bypass line shunts the primary pressure regulator or regulating valve for connecting the pipelines when the primary pressure regulating valve is disconnected from the pipelines. The bypass line includes an expander system having at least one expander for expanding the high pressure gas in the gas transmission pipeline and producing work and lower pressure gas that is supplied to the consumer pipeline. Preferably, a generator is coupled to the expander for converting work produced by the pressure regulating of the high pressure gas in the expander to electricity which is supplied to an electrical load. A fast acting, selectively adjustable pressure regulator or regulating valve apparatus is connected in parallel with the expander system. Finally, a control system is provided, responsive to a reduction in flow through the expander system for rapidly switching the apparatus from a non-operational state in which no gas is transmitted between the transmission and the consumer pipelines, to an operational state in which high pressure gas is throttled to the lower pressure in the consumer pipeline and transmitted thereto.

摘要： A fluid pressure reduction system includes at least two streams. A working stream includes valves with associated pressure sensors for modulating output pressure. A control system monitors pressure via a sensor and actuates a slam shut valve in the event of a fault. In the event that another stream is at fault the arrangement allows the slam shut valve to be opened. In the faulty stream only, pressure again rises, the slam shut is again shut and cannot be reopened until manually reset following fault clearance. Independent control in each stream assists in system integrity. All streams can close and reopen once. The second closure determines the faulty stream.
