Consider a mixture of two diatomic gases A and B at atmospheric pressure (1atm) with partial pressures PA=PB. We want to enrich this mixture in A by passing it through a metal membrane of thickness e (from left to right) as shown in Figure 1. The requirements are: a- The partial pressure of A is twice that of B at the outlet (in the right compartment) b- The total pressure in the right compartment is equal to 0.1atm. c- The flux of A through the membrane is twice that of B Find the operating temperature for this process to satisfy the requirements. The data on the diffusion of A and B through the membrane are: A:DOA=4107m2/s,QA=15000J/mole B::DB=2.5106m2/s,QB=10000J/mole The concentrations of A and B at the surface of the membrane (in mole/m3) are given by the following formulas: CA=100PAeRT20,000CB=10PBeRT30,000 Where PA and PB are the partial pressures of A and B (in MPa ), T is the absolute temperature in K Q1: Soit un mlange de deux gaz diatomique A et B la pression atmosphrique (1atm) avec des pressions partielles PA=PB. On dsire enrichir ce mlange en A en le faisant passer travers une membrane mtallique d'paisseur e (de gauche droite) tel qu'illustr la figure 1. Les exigences sont : a- La pression partielle de A soit le double de celle de B a la sortie (dans le compartiment de droite) b- La pression totale dans le compartiment de droite est gale 0.1atm. c- Le flux de A travers la membrane est le double de celui de B Trouver la temprature de fonctionnement de ce processus pour satisfaire les exigences. Les donnes sur la diffusion de A et B travers la membrane sont : Pour A : Do OA=4107m2/s,QA=15000J/ mole Pour B::DoB=2.5106m2/s,QB=10000J/mole Les concentrations de A et B la surface de la membrane (en mole/m3 ) sont donnes par les formules suivantes : Pour A: CA=100PAeRT20,000 Pour B : CB=10PBeRT30,000 Avec PA et PB sont les pressions partielles de A et B (en MPa), T est la temprature absolue en K
