882 MINERALS YEARBOOK, 1972 DOMESTIC PRODUCTION Production of fixed nitrogen increased by 2% in 1972, but this percentage should be viewed with caution since final production figures have, in general, been revised upward at later dates. About 33,000 standard cubic feet of natural gas was required to produce 1 ton of anhydrous ammonia; therefore, about 470 billion standard cubic feet of natural gas was used to produce synthetic ammonia in 1972. The production of ammonia accounted for roughly 2% of the domestic consumption of natural gas. Domestic ammonia plants produced at about 84% of the total maximum domestic capacity, up from 81% of capacity in 1971. All of the domestic plants combined will probably have difficulties producing at a combined rate much over 90% of capacity. It can be seen, therefore, that production moved toward effective capacity during 1972. The production of elemental nitrogen jumped by 15% in 1972. Farmland Industries, Inc., announced plans to build an ammonia plant near Enid, Okla. Capacity was scheduled to be 380,000 tons per year when the plant comes onstream in 1974, and natural gas feedstock for the plant was to be supplied by Oklahoma Natural Gas Co. Mid-America Pipeline Co., Inc. (MAPCO) planned to construct a 6-inch-diameter pipeline, 115 miles in length, from the Farmland Industries plant to MAPCO's existing ammonia pipeline southwest of Hutchinson, Kans. Farmland Industries also announced plans to construct 30,000-ton -ammonia storage terminals in Nebraska, Iowa, and Minnesota. Total cost of the Farmland Industries project was expected to exceed $30 million.2 CF Industries, Inc. was planning to build a 1,000-ton-per-day urea plant at its Donaldsonville, La., nitrogen complex where the company now operates two 1,000-ton-per-day ammonia plants. Also, the company planned to add regional warehouses for urea at four locations, with a total capacity of 100,000 tons. Later in the year, property owners adjacent to the proposed urea plant location took legal steps to enjoin construction of the plant on the basis of possible noise from the plant, the visual appearance of the plant, and possible emissions. No disposition of the dispute had been made at yearend.3 Shell Chemical Co. planned to drop out of the fertilizer production business with the closures of its ammonia and nitrogen products plants at Ventura, Calif., and St. Helens, Oreg. Reasons given for the closures were an oversupply of ammonia, spiraling operating cost, technological obsolescence and small production capacity of the plants, and shortage of natural gas feedstock. Later, Shell reached a tentative agreement with Reichhold Chemicals, Inc. for Reichhold to purchase the St. Helens, Oreg., facilities. Production capacity at St. Helens was 80,000 tons per year of ammonia and 50,000 tons per year of urea.4 Vicksburg Chemical Corp. planned to reopen the potassium nitrate plant formerly owned and operated at Vicksburg, Miss., by American Metal Climax, Inc. (AMAX) .5 Air Products & Chemicals, Inc., filed a legal action against United Gas Pipe Line Co. Air Products was seeking a declaratory judgment limiting the prices to be charged under a long-term natural gas supply contract. An injunction was also being sought to assure continued natural gas service while the matter was in litigation. United Gas supplied natural gas feedstock to Air Products' Escambia, Fla., plant which produced ammonia, methanol, and other industrial chemicals.6 American Cyanamid Co. discontinued its sales of high explosives, blasting caps, and related products. Low profit margins, a declining market, and rising cost of distribution and security were cited as reasons for the decision. The company planned to continue to sell amnionium nitrate for agricultural and blasting agent uses.7 ' Chemical Marketing Reporter. Ammonia by Pipeline Project Set by Mapco.
