Separation Of Gas Mixtures Via Batch Parametric Pumping : A Theoretical Study, Jose G. Lopez

Theses

An equilibrium plug?flow model, for the batch isothermal separation of a binary gas mixture in a pressure changing parametric pump, was investigated for the system propane?argon on carbon, with the aid of a G. E. Pack 4020 computer. Separation factors comparable to a temperature changing parametric pump are predicted by the model. A change in pressure of the gas mixture may be carried out very rapidly, compared with a temperature change of similar magnitude. The effects of temperature, pressure, concentration, and penetration are discussed.

A Theoretical Study Of Continuous Parametric Pumping At Constant Temperature, Philip Weingartner

Theses

A continuous parametric pump, operating at constant temperature with pressure as the driving force, is analyized by means of an equilibrium theory. A thorough explanation of the process and the resulting mathematical model reveal how the parameters effect pump performance. The experimental data cited agree well with the analytical results in the CO₂-He on silica gel system. Complete removal of the solute from one of the product streams can be achieved through the proper selection of penetration distances and pressure levels.

Separation Of Glucose - Fructose - Water Systems Via Thermal Parametric Pumping, Zikri Mostafa Ahmed

Theses

Series of experiments were carried out to determine the effect of different factors on adsorption from aqueous solutions of sugar using fuller's earth ( LW 16-30 Mesh ) as an adsorbent. The equilibrium data were fitted to the Langmuir's equation., and an explanation for the deviation of some of these data has been given.

Systems of glucose-fructose and water mixtures were subjected to semi-continuous and continuous parametric pumping operations using activated carbon (400 Filterasorb) as an adsorbent. The results obtained confirm the equilibrium theory of the parametric pump and essentially fulfill the requirements established by Chen and Hill (6) to …
