An Experimental Study Of Separation Of Binary And Ternary Gas Mixtures By Parametric Pumping, Stephen E. Belsky
An Experimental Study Of Separation Of Binary And Ternary Gas Mixtures By Parametric Pumping, Stephen E. Belsky
Theses
An experimental study of gas parametric pumping is presented which examines the purification of helium using silica gel to remove the impurity carbon dioxide. Low gas flow rates are used to allow adequate time for equilibrium to be approached, assuming intraparticle diffusion is the controlling mass transfer step. By varying the cycle time, at long cycle times, the effect of penetration length (a function of dynamic capacity) is indicated. Also, at low cycle time, the effects during pressure changes become more significant.
Using low flow rate improves separation effectiveness if evaluated at equal dynamic capacity. When using low flow rate …

Non-Equilibrium Parametric Pumps For Separating Liquids Or Gases, Anil Krishna Rastogi
Theses
An experimental and theoretical study has been done of Non-Equilibrium parametric pumps. Mathematical models and computer programmes are developed for both thermal and heatless parametric pumps based on non-equilibrium conditions and linear isotherms. A mathematical study was done for thermal parametric pumps whereas both experimental and theoretical studies were made for a heatless parametric pump. The effect of different operating conditions has been investigated on the separation of NaCl-H2O via a thermal parametric pump and He-CO2 and He-C3H6 gas mixtures via a heatless parametric pump.
The experimental study of heatless parametric pumps was extended …
