WORLD REVIEW 
 Recent major expansions in the ammonia industry worldwide have resulted
in overcapacity. Centrally planned economy countries, particularly the U.S.S.R.,
and developing nations have been claiming an increasingly greater share of
world ammonia supply capability. A large portion of this new capacity is
based on abundant supplies of low-cost feedstock, and much of the output
is intended for export markets at very competitive prices. In fact, world
ammonia trade grew markedly in 1978 and 1979, with the Soviets emerging as
the world leader in ammonia exports. Production problems at various locations,
including the U.S.S.R., Mexico, and the Netherlands, along with 
escalating naphtha costs, contributed to a 
tightening of wOrld supply and higher world 
ammonia prices during 1979. 
 Abu Dhabi.—A contract was awarded for the construction of a 1,100-ton-per-day
ammonia plant and a 1,650-ton-per-day urea unit by 1981.'~ 
 Algeria.—An ammonia plant with a capacity of 300,000 tons per
year
of nutrient was under construction at Arzew along with downstream units."
 Bahrain.—A joint venture, BahrainKuwait Petrochemical Industries,
was formed to construct and operate a 1,100-tonper-day ammonia plant at Sitra
using natural gas feedstock.16
