TL;DR: In this paper, an integrated refueling system comprises a fluid circuit including multiple flow paths for directing natural gas to a natural gas liquefier, where a portion of the resulting liquefied natural gas is provided to a LNG delivery location.
Abstract: An integrated refueling system comprises a fluid circuit including multiple flow paths for directing natural gas to a natural gas liquefier. A portion of the resulting liquefied natural gas is provided to a liquefied natural gas delivery location. Another portion of the liquefied natural gas may be provided to a compressor and subsequently a heat exchanger/vaporizer to produce compressed natural gas. The heat exchanger/vaporizer may utilize the lower temperature of liquefied natural gas to precool incoming gaseous natural gas while simultaneously vaporizing the pressurized, liquefied natural gas to form the compressed natural gas. Compressed natural gas may be provided at a compressed natural gas delivery location.

TL;DR: In this paper, a two-screw compressor rotors are formed from a hobbing cutter and the rotor together constitute a pair of crossed helical gears, which are then used to transform the rotor into a cross-helical gear.
Abstract: Twin-screw compressor rotors are effectively helical gears. When these are formed from a hobbing cutter, the hobbing tool and the rotor together constitute a pair of crossed helical gears. ...

10 Oct 2001TL;DR: In this article, an internal combustion engine including an exhaust gas turbocharger and a compound power turbine connected to the crankshaft of the engine and a recirculation system extending between the engine exhaust duct upstream of the exhaust gas turbine and the intake duct downstream of the compressor of the turbine.
Abstract: In an internal combustion engine including an exhaust gas turbocharger and a compound power turbine connected to the crankshaft of the engine and an exhaust gas recirculation system extending between the engine exhaust duct upstream of the exhaust gas turbine and the intake duct downstream of the compressor of the exhaust gas turbocharger, the exhaust gas turbine and the compound power turbine have a size relationship determined by the power absorption capability φ of each turbine such that: φ = m T p wherein: {dot over (m)} is the exhaust gas mass flow rate through the turbine, T is the exhaust gas temperature at the turbine inlet, and p is the exhaust gas pressure at the turbine outlet and the maximal compound power turbine absorption capability exceeds the maximal absorption capability of the exhaust gas turbine
