Pressure swing adsorption reliability

In the development of the steam-reforming route to ammonia, for many years there has been a desire to eliminate the steam-reforming furnace for reasons of capital cost, efficiency, and reliability. This technology has now been demonstrated on a commercial scale by ICI with the LCA process. With this process the plant is simplified by the use of a Gas Heated Reformer (GHR) in which the primary reformer receives heat directly from the process gas leaving the secondary reformer. This compact pressurized reformer eliminates the massive furnace structure and the high-pressure steam system of a conventional plant. A pressure swing adsorption...
