Selective permeation and separation of steam from water ...

2008-3-31  The separation factor of water/hydrogen and water/methanol were 49–156 and 73–101, respectively. Even when only hydrogen was fed at 0.5 MPa, its permeance was as low as 10 −9 mol m −2 s −1 Pa −1 up to 493 K, possibly suggesting that water pre-adsorbed in the micropores of mordenite hindered the permeation of hydrogen.

THE METHANOL PROCESS, A BASIC INTRODUCTION

2010-4-14  Water, (various types): Water is essential to Methanol production. Over 3000 metric tons of very clean ‘new’ water is required every day for duties varying from providing domestic drinking water (called potable water), to water that will be boiled to make steam. The methanol process produces and consumes a lot of steam.
