The ammonia plant that Pullman Kellogg has designed for Sherritt-Gordon Mines Ltd. in Alberta will require < 27 million Btu/ton of ammonia, and save $8.10/ton in energy costs because of improvements involving increased pressure in the primary reformer; more efficient use of the heat from the secondary reformer; carbon dioxide recovery by Allied Chemical Corp.'s Selexol process; the reduction of power requirements in the synthesis recycle loop; and the use of a horizontal reactor. C. F. Braun and Co. claims that its Purifier process will require < 25 million Btu/ton, due to the use of excess air in the secondary reformer. C-E Lummus offers a 1500 ton/day plant which, incorporating cryogenic recovery of hydrogen from purge gas and operation at a lower steam-to-carbon ratio, would require only 26 million Btu/ton; Haldor Topsoe Inc. offers a design rated at 26.3 million Btu/ton. According to L. C. Axelrod of Pullman Kellogg, ammonia plant construction will shift to gas-rich areas outside the U.S. and Europe. The 3% of the U.S. natural gas used by the fertilizer industry accounts for > 95% of ammonia feedstock.
