The natural gas temperature and pressure regulating system based on recovering pressure energy and absorbing heat from ultralow temperature ambient environment. A pressure driven heating system of pipeline natural gas pressure regulation or liquid natural gas regasification process. This system adopts vortex tube, ambient air heat exchanger and ejector that constitute the pressure driven heating unit to replace the existing heater. The two kinds of pressure driving devices of an ejector and a vortex tube are adopted, transmit the low temperature NG at the cold end of the vortex tube into the ambient air heat exchanger to absorb heat from the ambient continuously; at the same time, make temperature of the gas from the hot end of the vortex tube increase to meet the required temperature of pipeline directly, then achieve the purpose of no heater energy consumed.

Systems and methods for dockside regasification of liquefied natural gas (LNG) are described herein. The methods include providing LNG from a LNG carrier to a regasification vessel. The LNG may be regasified on the regasification vessel. The regasified natural gas may be discharged with a high pressure arm to a dock and delivered onshore. The regasification vessel may be moored to the dock. The LNG carrier may be moored to the regasification vessel or the dock.

A liquefied natural gas transportation/distribution and vaporization management system includes a transportation/distribution platform, on which at least one gas transportation/distribution section, a vaporization treatment section, and a central management section are arranged. The gas transportation/distribution section allows at least one liquefied natural gas train to unload liquefied natural gas. The vaporization treatment section is connected to the gas transportation/distribution section. The vaporization treatment section includes therein at least one fuel cell module, so that heat exchange may be conducted with byproduct of thermal energy and water generated in a power generation operation of the fuel cell module to vaporize liquefied natural gas from the gas transportation/distribution section and to feed the vaporized natural gas into a local area gas supply pipeline or a temporary gas storage section for storage and for feeding to the fuel cell module of the vaporization treatment section. The central management section receives the electrical power generated by the fuel cell module of the vaporization treatment section and is connected to and controls transportation/distribution and vaporization of the liquefied natural gas and management, monitor, and control of the output of the vaporized liquefied natural gas of the gas transportation/distribution section and the vaporization treatment section.

A system that can offload compressed gas from a storage tank to a customer site. The system can have a fluid circuit that is configured to fit within a container structure, like a trailer, for mobility to remote locations. This fluid circuit can include a transfer unit to automatically switch between tanks. The transfer unit can couple with a heat exchanger. Downstream of the heat exchanger, the fluid circuit can reduce pressure of fluid from the tanks through multiple pressure reduction stages. Each of the pressure reduction stages can include a throttling device, for example, a pilot-type fluid regulator and a control valve assembly. The throttling device may be selected to maintain flow of fluid at least at, e.g., 35,000 scfh, in accordance with pressure drops in the incoming fluid from the tanks.

A fluid transfer system, including a first stage, including an inlet, a surge tank, and a first cylinder operatively arranged to pump the fluid from the inlet to the surge tank, and a second stage, including an outlet, a knock out tank, and a second cylinder operatively arranged to pump the fluid from the surge tank into the knockout tank.
