2013-06-03An equation and a set of mixing rules for the prediction of liquid density of pure refrigerants and liquified natural gasLNG.multicomponent systems have been developed. This equation uses the parameters of Mathias and Copeman wP.M. Mathias, T.W. Copeman, Fluid Phase Equilib. 131983.91–108x te..

2013-06-03Abstract Swelling and shrinkage (volumetric change) of coal during adsorption and desorption of gas is a well-known phenomenon. For coalbed methane recovery and carbon sequestration in deep, unminable coal beds, adsorption-induced coal volumetric change may cause significant reservoir permeabilit..

2013-06-03This paper describes a method for measuring the mass of cryogenic fluids in on-board rocket propellant tanks or ground storage tanks. Linear approximations to the Clausius–Mossotti relationship serve as the foundation for a capacitance based mass sensor, regardless of fluid density stratificati..

2013-06-03An analysis of cryogenic liquefaction and storage methods for in-situ produced propellants (oxygen and methane) on Mars ispresented. The application is to a subscale precursor sample return mission, intended to demonstrate critical cryogenic technologies prior to a human mission. A heat transfer ..

2013-06-03Based on a presentation to 82nd Annual GPA Convention, Dallas, Mar. 11-13, 2002.A comparison of LNG processes for tropical conditions showed that Shell double mixed refrigerant (DMR) process is a competitive alternative for the propane mixed refrigerant (C3MR) process. For both processes, an end-..

2013-06-03Commercial sorption-based air separation is usuallydone using nitrogen selective zeolites in pressure swing adsorption (PSA) systems. Separation of air byadsorption of less abundant oxygen is more desirable. In this studywe have developed some stable oxygen selective sorbents with silver and ceri..

2013-06-03Optimisation techniques are used for the design of novel forced-periodic reactors in which there is the integration of catalyticreaction, adsorptive separation and direct #uid to solid heat exchange within a single unit operation. For such con"gurations,dynamic operation is utilised to gener..

2013-06-03A non-equilibrium molecular dynamics simulation was adopted to calculate the diffusion coefficients for a pseudo-binary system of carbon dioxide and for a carbon dioxide+ solute system at 308.2 and 318.2 K. The calculated results were compared with the self- and tracer diffusion coefficients calc..

2013-06-03A joint industry project focused on the use of liquefied natural gas (LNG) on the West Coast aims to identify and address barriers for LNG as a marine fuel in Canada. The estimated $1.2 million project involves 17 participating organizations including Port Metro Vancouver, BC Ferries, Seaspan, an..
