In one aspect, a system for controlling the temperature within a gas adsorbent storage vessel of a vehicle may include an air conditioning system forming a continuous flow loop of heat exchange fluid that is cycled between a heated flow and a cooled flow. The system may also include at least one fluid by-pass line extending at least partially within the gas adsorbent storage vessel. The fluid by-pass line(s) may be configured to receive a by-pass flow including at least a portion of the heated flow or the cooled flow of the heat exchange fluid at one or more input locations and expel the by-pass flow back into the continuous flow loop at one or more output locations, wherein the by-pass flow is directed through the gas adsorbent storage vessel via the by-pass line(s) so as to adjust an internal temperature within the gas adsorbent storage vessel.

A gas analysis device is provided that is able to accurately measure a concentration or a quantity of methane contained in a sample gas even if there are variations in the pressure in the sample gas line. This gas analysis device has a sample gas line through which a sample gas flows, a pressure loss mechanism that is provided on the sample gas line, a pressure control mechanism that refers to the pressure on the forward side of the pressure loss mechanism and, by discharging a portion of the sample gas from the rearward side of the pressure loss mechanism, and by supplying a predetermined gas to the rearward side of the pressure loss mechanism, controls pressure differences in the sample gas line between the front and the rear of the pressure loss mechanism, and an analyzer that analyzes the sample gas flowing through the sample gas line.

Method of stopping and restarting production in an undersea bottom-to-surface connection production pipe having a first pipe portion on the sea bottom from a well head to the bottom end of a second pipe portion extending to a ship or floating. When production is stopped, at least the first pipe portion is filled with a depressurized production fluid. Thereafter the following steps are performed: e1) forming a gel from two reagents in a first gel-forming chamber on the sea bottom; e2) sending a quantity of separator gel into the first pipe portion that pushes the cold fluid contained in the first pipe portion to the second pipe portion, prior to closing the first chamber; and then; e3) starting production, the gel forming physical separation and thermal and chemical isolation between firstly the production fluid and secondly a production fluid within the first production pipe portion.

Embodiments of the present disclosure describe methods of removing one or more compounds from a fluid comprising contacting a metal-organic framework (MOF) composition having a square-octahedral topology with a fluid containing one or more of CH.sub.4 and O.sub.2, sorbing one or more of CH.sub.4 and O.sub.2 with the MOF composition, and storing one or more of the CH.sub.4 and O.sub.2 with the MOF composition.

The porous gas sorbent monolith includes a gas adsorbing material and a non-aqueous binder.

Systems and methods to create and store a liquid phase mix of natural gas absorbed in light-hydrocarbon solvents under temperatures and pressures that facilitate improved volumetric ratios of the stored natural gas as compared to CNG and PLNG at the same temperatures and pressures of less than ?80? to about ?120? F. and about 300 psig to about 900 psig. Preferred solvents include ethane, propane and butane, and natural gas liquid (NGL) and liquid pressurized gas (LPG) solvents. Systems and methods for receiving raw production or semi-conditioned natural gas, conditioning the gas, producing a liquid phase mix of natural gas absorbed in a light-hydrocarbon solvent, and transporting the mix to a market where pipeline quality gas or fractionated products are delivered in a manner utilizing less energy than CNG, PLNG or LNG systems with better cargo-mass to containment-mass ratio for the natural gas component than CNG systems.

A method of storing gas comprises providing a recipient for receiving the gas and providing a porous gas storage material. The gas storage material comprises a cross-linked polymeric framework and a plurality of pores for gas sorption. The cross-linked polymeric framework comprises aromatic ring-containing monomeric units comprising at least two aromatic rings. The aromatic ring-containing monomeric units are linked by covalent cross-linking between aromatic rings to form a stable, rigid nanoporous material for storing the gas at pressures significantly greater than the atmospheric pressure, for example in excess of 100 bar. A possible application is the storage and transportation of compressed natural gas.
