Quantitative gas analysis apparatus
Abstract
Abstract APPARATUS FOR PERFORMING A CONTINUOUS QUANTITATIVE ANALYSIS OF THE HYDROGEN PRESENT IN A GASEOUS MIXTURE, THE APPARATUS ESSENTIALLY INCLUDING A DIFFUSION CELL PRESENTING A FIRST GAS FLOW SPACE FOR THE PASSAGE OF THE GASEOUS MIXTURE WHOSE HYDROGEN CONTENT IS TO BE ANALYZED, A SECOND GAS FLOW SPACE FOR THE PASSAGE OF A CARRIER GAS, AND A SEMIPERMEABLE MEMBRANE WHICH IS ESSENTIALLY PERMEABLY ONLY TO HYDROGEN AND WHICH IS DISPOSED BETWEEN THE TWO SPACES SO THAT THE HYDROGEN DIFFUSING THROUGH THE MEMBRANE WILL BE ENTRAINED BY THE CARRIER GAS, THE APPARATUS FURTHER INCLUDING A KATHAROMETER HAVING ONE INLET CONNECTED TO RECEIVE THE CARRIER GAS BEFORE IT PASSES TO THE DIFFUSION CELL AND A SECOND INLET FOR RECEIVING THE HYDROGEN-LADEN CARRIER GAS LEAVING THE DIFFUSION CELL, THE KATHAROMETER PROVIDING AN INDICATION OF THE DIFFERENCE BETWEEN THE THERMAL CONDUCTIVITIES OF THE TWO GASES WHICH IT RECEIVES, WHICH DIFFERENCE IS REPRESENTATIVE OF THE INITIAL HYDROGEN CONTENT OF THE GASEOUS MIXTURE BEING ANALYZED.
