Particle Trajectories in a Gas Centrifuge [PDF]

Journal of Basic Engineering, 1961
The motion of spherical particles injected into a cylinder of gas which rotates as a solid body has been studied. The particle trajectory is expressed explicitly as a function of two dimensionless parameters; an injection-velocity parameter and an inertial parameter which is roughly the ratio of centrifugal force to drag force on the particle. The main

Centrifuge experimental study on instability of seabed stratum caused by gas hydrate dissociation [PDF]

Ocean Engineering, 2015
Gas hydrate (GH) is a kind of solid energy resource with huge reserve. Stratum instability (such as marine landslide) may be caused by hydrate dissociation due to the softening of stratum and the buildup of excess pore pressure.

Modeling and Control of a Wet-Gas Centrifugal Compressor

IEEE Transactions on Control Systems Technology, 2021
The development and production of small gas condensate discoveries require cost-efficient boosting technologies for profitable production. Subsea wet-gas compression is a new boosting technology, capable of boosting gas condensates containing up to 5% liquid per volume, removing the need for preseparation of the gas condensate, and resulting in lower ...

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 ...
