Abstract:
A system achieving a high density of transported natural gas by compressing it to high pressures typically above 5 MPa to transport the gas in a modified composition that permits a very low compressibility factor at near ambient temperature either above or below. This reduces greatly the size of the cooling systems that are required. In some cases cooling of the compressed gas may be achieved in a simple heat exchanger cooled by air or water. The transport of the gas takes place in self propelled ships or non-self propelled barges fitted with a cargo containment system capable of storing the cargo at high pressures, typically above 5 MPa and usually not above 25 MPa. The transport vessel may carry a store of higher molecular weight gases (c2 through c7) that when mixed with the incoming cargo results in a molecular weight of the mixture of at least 22 and possibly as high as 28 or higher. The store of higher molecular weight cargo may be gained from gases that condense during discharge of the vessel at its destination due to the adiabatic cooling of the cargo during discharge. These liquids may be retained aboard and transported back to the origin. If insufficient quantities of heavy gases are available at the origin they may be loaded at the destination. If required, the composition of the heavy gases transported back to the origin may be changed through partial discharge or partial receipt of additional hydrocarbons or a combination thereof at the destination point.

Abstract:
An anti theft device (100) for an LPG cylinder is disclosed wherein a flow restrictor means and a weighted magnet is located within a body (3). The body (3) is fitted to a fitment means (1) for fixing the anti theft device (100) of the present invention to the cylinder bung or the cylinder valve. The anti theft device (100) of the present invention operates on the principle of differential pressure. The anti theft device (100) for the LPG cylinder besides preventing the pilferage of the liquid LPG or excess usage, also aids in providing safety against accidental leakage during domestic usage.
Abstract:
System for transport and storage of compressed natural gas (CNG) at high pressure (HP) and distribution of said natural gas at high pressure (HP), medium pressure (MP) and low pressure (LP), which system is distinguished in that the layout thereof is such that during fluid communication to or between units of the system or internally between tanks of the separate units a closed loop can be formed wherein gas at specific pressure is transported from one or more first tanks to one or more other tanks while liquid at the same pressure as the gas or at marginally higher pressure is transported from said one or more other tanks to said one or more first tanks, the volume of said one or more first tanks being approximately equal to the volume of said one or more other tanks. Process using the above-mentioned system.
Abstract:
A gas delivery system and a gas delivery method are provided. The gas delivery system comprises a gas storage unit (10), a power unit (20) and a gas refueling unit (90). The gas storage unit (10) comprises two groups of cylinders having the same number of the cylinders. Each cylinder is provided with a first valve and a second valve respectively at its two ends. The gas storage unit (10) comprises a first medium pipeline (11), a second medium pipeline (12), and a gas discharge pipeline (13). All the cylinders are connected to the gas discharge pipeline (13) via their respective second valves. Each cylinder in the first group (Gl) is connected to the second medium pipeline (12) via its first valve. The power unit (20) comprises a tank (21) for storing medium, a pump (22) for providing the medium from the tank (21) to the gas storage unit (20), and a medium connecting pipeline comprising a reversing valve manifolds (24). The gas refueling unit (90) comprises a dispenser (91) connected to the gas discharge pipeline of the gas storage unit. According to the gas delivery system and the gas delivery method, the manufacture cost is lowered, the potential leakage and/or failure points are reduced and the operational security is promoted.
Abstract:
A portable kit box for torch equipment comprising a lid, a tank compartment for holding at least one tank, and a base. The base defines a base surface for contacting and translating the kit box along a surface. The lid comprises a compartment for storing at least one tank and is movable between an open position and a closed position. The kit box has at least three positions relative to the surface. In the first position, the at least one tank is supported at an acute angle relative to the surface, in the second position the at least one tanks is supported approximately perpendicular to the surface, and in the third position, the at least one tank is supported approximately horizontal to the surface. The kit box further includes at least one storage compartment, a securing member for securing the lid to the base, and a handle.
Abstract:
A manually moveable truck for transporting load units has a carrying device (1) arranged to carry load units and a wheel arrangement (2) connected to the carrying device for bearing upon a first support surface. The carrying device has at its one end a handle (7) for manipulating the truck. Furthermore, the wheel arrangement and the carrying device are provided with mutually co-operating guiding means (10, 14) being arranged so that the wheel arrangement is guidedly displaceable with respect to the carrying device in the direction towards and away from said handle end. There are also means for securing the wheel arrangement and the carrying device to each other. In a position suitable for moving the truck on the first support surface, the wheel arrangement (2) is displaceable with respect to the carrying device (1) to the region of the handle (7), after loosening said securing means (25), so that holding the wheel arrangement (2) with its wheels (15) in a fixed position upon the first support surface the carrying device with the load units may be pushed on to a second support surface (26)lying at a higher level than the first one. The wheel arrangement (2) may be brought to bearing upon the second support surface by completely removing it from the carrying device and/or pivoting it upwardly past the handle (7).
