Liquefied Natural Gas Developments Specialreport
A multi-tube, spirally-wound, cryogenic heat exchanger, the main heat exchanger (MHE) is the principal piece of heat-transfer equipment in mixed-refrigerant liquefaction cycles for producing liquefied natural gas (LNG). An MHE unit operation model called the spirally-wound tube-bundle module was developed as an integral component of the dynamic simulation capabilities for a process modeling pac...
متن کاملThe carriage of liquefied gases
Introduction The renewed interest in gas, which started in the 1990s due to its excellent environmental credentials, has seen an increase in the order book for LNG carriers – LNG carriers being the leviathans of the gas carrier fleet. Yet, while attracting great interest, the gas trade still employs relatively few ships in comparison to oil tankers, and hence its inner workings are little known...
متن کاملDynamics of Liquefied Sediment Flow 95 the Dynamics of Liquefied Sediment Flow Undergoing Progressive Solidification
The propagation of solidified zones in the course of subaqueous liquefied sediment flow is theoretically discussed. The coupled systems of Navier-Stokes equations and consolidation equation are numerically solved under moving boundary conditions, with consideration of the concurrent evolutions of the flow surface as well as of the internally formed interface between the fluid and solidified zon...
متن کاملLiquefied Natural Gas for Trucks and Buses
Liquefied natural gas (LNG) is being developed as a heavy vehicle fuel. The reason for developing LNG is to reduce our dependency on imported oil by eliminating technical and costs barriers associated with its usage. The U.S. Department of Energy (DOE) has a program, currently in its third year, to develop and advance costeffective technologies for operating and refueling natural gas–fueled hea...
متن کاملArtificial Molecules: Antibonding Molecular Ground State for Holes Revealed
Semiconductor quantum dots have long been described as artificial atoms because they have discrete energy states analogous to the energy levels of natural atoms. In recent years, it has become possible to create coupled pairs of quantum dots that are analogous to natural diatomic molecules. These artificial molecules have received a great deal of attention because of the potential applications ...
