Dependence of the separative power of an optimised Iguassu gas centrifuge on the velocity of rotor [PDF]

International Journal of Numerical Methods for Heat and Fluid Flow, 2017
Purpose The purpose of this work is to determine dependence of the separative power of the Iguassu gas centrifuge (GC) on the velocity of the rotor. Design/methodology/approach The dependence is determined by means of computer simulation of the gas ...

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.

The evolution of liquid and gas centrifuges

Endeavour, 1978
Abstract Although the principle of separation by centrifugation has been known for nearly a century, the technical difficulties of using it in practice are very great. Only in comparatively recent years has there been sufficient understanding of the underlying theory, and availability of suitable materials of construction, for the high-speed ...

Gas Dynamic Designs of Centrifugal Compressors for Gas Industry

ASME 2015 Gas Turbine India Conference, 2015
Centrifugal compressors for gas industry consume huge amount of energy. As a rule, they are single-shaft, with two or more stages and with comparatively low pressure ratio. Compressors operate at low Mach numbers and high Reynolds numbers. Two design parameters influence mostly stage performances.

Online adaptation of performance maps for centrifugal gas compressors

2014 European Control Conference (ECC), 2014
This paper investigates the adaptation of different performance maps of centrifugal compressors driven by dualshaft gas turbines during operation. First the estimation of compressor, gas turbine and combined efficiency are considered. Obtaining performance maps is mainly based on fitting an empirical model to the history of past data together with the ...

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 ...

Separation Power of a Gas Centrifuge and Certain Errors in Optimizing the Centrifuge

Atomic Energy, 2002
The theory of separation in a Zippe centrifuge is developed. The physical meaning of the concept “separation power” is examined in application to a gas centrifuge. Ideas concerning the separation power in certain publications and the associated incorrect arguments concerning the optimization of a gas centrifuge are analyzed.

Gas absorption in a centrifugal reactor: hydrodynamics

Chemical Engineering Science, 1993
Abstract For the removal of SO 2 and/or NO x using an oxidizing liquid solution, absorbers with a high mass transfer efficiency are required. Here, a centrifugal gas—liquid absorber has been designed and studied; the chosen device is a rotor with blades which induce the formation of a thin liquid film on the reactor wall. The operating parameters
