Liquified natural gas (LNG) fueled combined cycle power plant and a (LNG) fueled gas turbine plant

A process and system which improves the capacity and efficiency of a power plant. A LNG supply system fuels the plant. Gasified LNG in a combustor mixes with the air from an air compressor to provide the hot combustion gas for a gas turbine. The expanding LNG is used to chill a heat exchange fluid, e.g. water, which heat exchange fluid cools and densifies the intake air for the air compressor. Subsequently, the heat exchange fluid is used in another heat exchange step and is then re-chilled and recycled to cool and densify the intake air.

Apparatus and method for flowing compressed fluids into and out of containment

Methods for loading a compressed fluid, such as natural gas, into and discharging the compressed fluid out of containment are provided. The compressed fluid is injected into a bottom portion of a container system for storage and / or transport until a target pressure is reached after which gas is withdrawn from an upper portion of the container system at a rate to maintain the target pressure while the compressed fluid is injected in the bottom portion. The compressed fluid is cooled through an expansion valve and by refrigerated chillers or by injecting a cold liquid of the same chemical composition as the compressed fluid, such as liquid natural gas, into the compressed fluid prior to injection into the container system. Withdrawal or discharge from the container system to a receiving facility begins with blow down from the bottom portion of the container system without a displacement fluid and continues until pressure falls below an acceptable differential pressure. The discharge stream is passed through a separator and a light gas from the separator is pressurized and injected into an upper portion of the container system to drive the compressed fluid out the bottom. The light gas is pressurized using either a compressor or a heated tank system, where two vessels operate in parallel, trapping and heating the light gas and then discharging to the container system from one while filling the other and alternating the operation between the two.

Modular fluid flow system with integrated pump-purge

This disclosure describes a modular, monolithic pump-purge system which can be integrated into a modular, monolithic fluid handling system without creating a closed tolerance loop. In particular, the pump-purge system comprises a plurality of valves mounted on a modular and monolithic manifold which can be attached to the modular, monolithic fluid handling system. At least a portion, and preferably all of the fluid transfer conduits necessary for either applying a vacuum (or other evacuation means) to a fluid handling system conduit which is to be evacuated (pumped), or for transfer of flushing fluid within a conduit (purging) are present within monolithic manifolds of the fluid handling system. The modular, monolithic manifold of the pump-purge system contains openings and fluid flow conduits which correspond with openings and fluid flow conduits of the modular, monolithic fluid handling system, to enable evacuation or flushing of a selected fluid flow conduit within the fluid handling system. To avoid the formation of a closed tolerance loop, it is necessary that the pump-purge manifold or a portion of the modular, monolithic fluid handling system manifold to which it is attached be sufficiently free-floating to permit making of all necessary connections without creating stress which can lead to an increased rate of corrosion or failure of the connection. In a preferred embodiment gas handling system, the gas handling flow lines which make up the system are comprised of individual sticks of gas handling elements, each of which is attached to the manifold of the pump-purge system so that it is free-floating.

Liquid and compressed natural gas dispensing system

A system dispenses both liquid natural gas (LNG) and compressed natural gas (CNG). A bulk tank contains a supply of LNG which is pumped to a smaller storage tank. After the storage tank is refilled, LNG from the bulk tank is pumped to a vaporizer so that CNG is produced. The CNG may be routed to the LNG in the storage tank to condition it. It is also used to recharge a pressurizing cylinder that is placed in communication with the head space of the storage tank when it is desired to rapidly dispense LNG to a vehicle. A bank of cascaded storage cylinders alternatively may receive CNG from the vaporizer for later dispensing through the system CNG dispenser. The CNG from the vaporizer may also be dispensed directly via the system CNG dispenser.

Diagnostic method and apparatus for a pressurized gas supply system

ActiveUS7568507B2Prevent excessive pressure risePreventing a potentially dangerous overheating problemLiquid fillingGas handling applicationsLine tubingEngineering
A diagnostic method for a gas supply system includes: determining a desired ramp rate for filling a vessel from a supply of compressed gas; monitoring the actual pressure of gas entering the vessel; and discontinuing the flow of gas into the vessel when the actual pressure deviates from the intended pressure at the desired ramp rate by an undesired amount. A system for carrying out the method includes a flow controller for controlling operation of the supply system to deliver compressed gas from a source to a vessel through a supply line at a desired ramp rate. The system employs a pressure monitor downstream of a control valve for measuring the pressure of gas directed into the vessel and transmitting pressure-related data to the flow controller, which closes the control valve to discontinue filling of the vessel if the actual pressure exceeds a permissible deviation from the intended pressure.
