Nitrogen Engineering Corporation

NEC [Nitrogen Engineering Corporation] A modification of the Haber process for making ammonia. 

An estimate of world ammonia capacity for 1932-33, showed that the Haber-Bosch process represented 53 per cent, Casale 16 per cent, Fauser 11 per cent, Claude 8 per cent, Mont Cenis 6 per cent, Nitrogen Engineering Corporation (USA) 5 per cent, and Showa Hiryo (Japan) 1 per cent. Together the various operational plants had the ability to produce three million tons of ammonia nitrogen, though by 1935 only 43 per cent of this figure was actually manufactured. ... 

Meanwhile, an independent development took place in the USA. As early as 1918 a plant called US Nitrate Plant No. 1 was constructed in Muscle Shoals, Alabama. This plant was, however, not very successful, but the American development continued, and during the 1920s several successful plants were constructed, some based on American, some on European technology. In 1928, the Nitrogen Engineering Corporation (NEC) was commissioned to construct a plant in Europe [49], thereby entering the worldwide competition.
