Benefits
Making a gaseous product in a membrane reactor generally affects the way that pressure affects the extent of reaction at thermodynamic pseudo-equilibrium. In an ordinary flow reactor, the composition of the exhaust gas is determined by the composition of the feed gas and the extent of reaction. As a result, at pseudo-equilibrium, the extent of reaction is entirely determined by the feed composition and the exhaust equilibrium constant, the latter being determined by the temperature and pressure of the exhaust. In a membrane reactor, the partial pressure of the components at psueudo-equilibrium are not uniquely determined by the total pressure, exit temperature, and feed composition. There is also a significant (and beneficial) effect that derives from the controlled removal of a product or addition of reactant.

Famous quotes containing the word benefits:
“Through all opposition the personal benefits of the reform [dress] [bracketed word in original] have compensated; but had it been mainly sacrifice, the thought of working for the amelioration of women and the elevation of humanity would still have been the beacon-star guiding me on amid all discouragements.”
—Susan Pecker Fowler (1823–1911)
“It is with benefits as with injuries in this respect, that we do not so much weigh the accidental good or evil they do us, as that which they were designed to do us.—That is, we consider no part of them so much as their intention.”
—Laurence Sterne (1713–1768)
“One of the benefits of a college education is, to show the boy its little avail.”
—Ralph Waldo Emerson (1803–1882)
