摘要

Ammonia was produced by 15 companies at 26 plants in 16 states in the United States during 2005. Fifty-five percent of the U.S. ammonia production capacity was centered in Louisiana, Oklahoma and Texas because of their large reserves of natural gas, the dominant domestic feedstock. In 2005, U.S. producers operated at about 66 percent of their rated capacity. Five companies accounted for 81 percent of the U.S. ammonia production capacity. They included, in descending order, Koch Nitrogen, Terra Industries, CF Industries, Agrium and PCS Nitrogen. The United States remained the world's second ranked ammonia producer and consumer, following China. Urea, ammonium nitrate, ammonium phosphates, nitric acid and ammonium sulfate were the major derivatives of ammonia in the United States, in descending order of importance.
