Convective Flow during Gas Centrifugation

Industrial & Engineering Chemistry Research, 2004
In this addendum, supplemental to recently reported work on centrifugal separation of natural gas, we consider the effect of nonzero convective flow, which we had previously neglected as it had been assumed to be nearly zero. Here, we show that it is not necessary to assume that convective flow is zero, which also leads to the conclusion that, contrary

Centrifugation equilibrium of natural gas

Chemical Engineering Science, 2005
The problem of determining the pressure and composition profiles of natural gas under centrifugation is formulated and solved as the minimization of a modified Helmholtz function that includes the contribution of the centrifugal field. Fluid properties are calculated using the Peng-Robinson equation of state but the procedure can be readily extended to

Optimization Studies for Gas Centrifuges

Separation Science and Technology, 2000
In this paper we give a brief introduction to the Onsager pancake model for the fluid dynamics of a gas centrifuge and a history of the pancake computer code. We then present a comprehensive study of separative performance using the hypothetical gas centrifuge parameters of the so-called “Iguacu machine.” In particular, we present: (a) the optimal ...

Centrifugal Separation for Cleaning Well Gas Streams

Industrial & Engineering Chemistry Research, 2004
An examination of centrifugal gas separation applied to natural gas wells shows that it has some technical advantages for bulk removal of souring components in highly contaminated streams. Different criteria from those used in traditional UF6 processing apply, and we develop and describe these.

Centrifugal Gas Compression Cycle

AIP Conference Proceedings, 2002
A centrifuged gas of kinetic, elastic hard spheres compresses isothermally and without flow of heat in a process that reverses free expansion. This theorem follows from stated assumptions via a collection of thought experiments, theorems and other supporting results, and it excludes application of the reversible mechanical adiabatic power law in this ...
