Abstract:
A method of transporting natural gas by liquefaction of natural gas at ambient temperature, achieved by mixing the natural gas at high pressure with a hydrocarbon that is a stable liquid at ambient temperature and ambient pressure. The hydrocarbon liquid may be crude oil or a distillate of crude oil. The method includes: liquefaction: mixing the natural gas with the hydrocarbon liquid at an ambient temperature and a high pressure to generate a liquid mixture, which contains the natural gas dissolved in the hydrocarbon liquid; shipping: transporting the liquid mixture using a marine tanker, during which the liquid mixture is maintained at ambient temperature and the high pressure; and regasification: at the destination, releasing a gas from the liquid mixture by lowering the pressure of the liquid mixture. The hydrocarbon liquid may be used multiple times.
Abstract:
A system and method of receiving field gas from a compressor station pipeline, and compressing the gas at a remote location with a modular compressor. The compressed gas is collected in a container and transported to a wellsite for use at the wellsite. The gas from the pipeline is directed to the container, and diverted to the modular compressor when pressure in the container approaches pressure in the pipeline. The modular compressor discharge is piped to the container, so that the container is filled with additional gas and at the discharge pressure of the modular compressor.

Abstract:
Provided are an LNG storage container with an inner shell, which is capable of efficiently storing LNG or pressurized LNG (PLNG) pressurized at a predetermined pressure and supplying the LNG or PLNG to a consumption place, and capable of reducing manufacturing costs by minimizing the use of a metal having excellent low temperature characteristic, and a method for manufacturing the same. The LNG storage container includes: an inner shell configured to store LNG inside; an outer shell configured to enclose the outside of the inner shell such that a space is formed between the inner shell and the outer shell; a support installed in the space between the inner shell and the outer shell to support the inner shell and the outer shell; and a heat insulation layer part installed in the space between the inner shell and the outer shell and configured to reduce a heat transfer.
Abstract:
An enclosure for containing cylinders includes an upper surface, a lower surface, opposing side walls spanning the upper and lower surfaces, and an end surface spanning the upper and lower surfaces, the upper surface, lower surface, side walls, and end surface defining an enclosed space. A plurality of inner walls divides the enclosed space to define bays. A removable door panel is opposite the end surface and includes dividers defining portions of the door panel corresponding to the bays. The enclosure includes a plurality of first contact pads, a plurality of first mounting plates, a plurality of second contact pads, and a plurality of second mounting plates. At least one first contact pad and at least one second contact pad is positioned in a corner of each bay and each portion, respectively, at an angle that is neither parallel or perpendicular to either the side walls or the upper surface.
Abstract:
An apparatus and method estimate fluid mass in a cryogenic tank that holds a multiphase fluid comprising a liquid and a vapor. The apparatus comprises a level sensor, a pressure sensor and a computer. The level sensor provides a parameter representative of a level of the liquid. The pressure sensor provides a pressure signal representative of vapor pressure inside the cryogenic tank. The computer is operatively connected with the level sensor and the pressure sensor to receive the parameter and the pressure signal, and is programmed to determine the level from inputs comprising the parameter, to calculate a first volume of the liquid from inputs comprising the level, and to calculate a first mass of the liquid from inputs comprising the first volume and the pressure signal.
Abstract:
Method for controlling the pressure in a transportable cryogenic tank (1), especially a tank (1) mounted on a transportable platform (2) capable of being moved by a truck, the tank (1) being made of steel and containing pressurized liquid hydrogen, the method comprising at least one of the following: continuously or periodically measuring the temperature in the tank (1) and continuously or periodically measuring the level of the liquid in the tank and, when the measured temperature exceeds a set upper temperature threshold (Ts) lying between minus 140° C. and minus 160° C., and, respectively, when the liquid level in the tank drops below a set liquid level threshold, the pressure in the tank (1) is limited to a value less than or equal to a set pressure threshold (Pmax) lying between 1.5 and 3 bar.

Abstract:
Systems and methods for installing a compressed natural gas housing apparatus to a vehicle are disclosed. The housing apparatus is configured to be retrofitted to existing cab liners used on refuse vehicles. The complete installation of the housing apparatus and roof liner are disposed below the roofline of the refuse vehicle. The housing apparatus can be configured to contain a variable number of compressed natural gas tanks. The housing apparatus is installed such that the length of the gas pipeline and electrical wiring connected to the apparatus from the vehicle engine and controller is minimized. The location of housing apparatus provides the additional safety of minimizing the exposure of the gas tanks to falling debris or prevent possible contact with the compressed natural gas tanks being damaged as vehicle travels under bridges, other low objects, or contact in the event of a rollover accident.
