648 MINERALS YEARBOOK, 1978-79 Bangladesh.—A natural-gas-based ammonia/urea complex with annual capacities of 300,000 and 267,000 tons of contained nitrogen, respectively, is anticipated onstream at Ashuganj in 1980.17 A 1,100-tonper-day ammonia plant, which will utilize natural gas from the Bakhrabad field, and downstream 1,900-ton-per-day urea unit are planned for Chittagong in the early 1980's.18 Mainland China agreed to help construct a small-scale ammonia/urea facility at Ghorashal.19 Bolivia.—Plans for two ammonia/urea complexes were announced in 1978. An ammonia plant with a capacity of 300,000 tons per year nitrogen content and a urea unit with 152,000 tons per year of nitrogen capacity were slated onstream in 1982 at Puerto Suarez. A small-scale facility was planned at Rio Grande.20 BraziL—Petrobras awarded a contract for the design and construction of a coal gasification plant at San Jeronimo, Rio Grande do Sul State, by 1983. Coal from the mines at Leao will be converted to synthesis gas using the Koppers-Totzek process for the production of 660 tons of ammonia per day.21 Bulgaria.—Contracts were signed for a 400-ton-per-day ammonia synthesis gas preparation unit and a 600-ton-per-day urea plant. The facility will be constructed at Vratsa by 1981.22 Burma.—A natural-gas-based ammonia plant with annual capacity of 107,000 tons of contained nitrogen and a urea unit with 100,000 tons of annual nutrient capacity have been scheduled onstream in 1983.23 Canada.—Esso Chemical Canada announced plans to begin construction of a 1,100-ton-per-day ammonia plant and a 1,650-ton-per-day urea unit in Alberta during 1981, with startup in 1983.24 China, Mainland.—With the completion of two facilities in 1979, all 13 large ammonia/urea complexes purchased from abroad in the early 1970's have been completed.~' Contracts for four additional 1,100-ton-perday ammonia plants, three based on fuel oil and one on coal gasification, have been awarded, and more are anticipated.26 Colombia.—Plans were announced for a 1,100-ton-per-day ammonia plant and a 1,650-ton-per-day urea plant at Guagira.27 Cuba.—Construction of a 1,430-ton-perday ammonia plant and two 1,100-ton-perday urea units at Cienfuegos has been proposed. The complex would utilize naphtha feedstock from local refineries.2~ Egypt.—Production from Abu Qir Ferti lizer & Chemical Products' ammonia plant with a capacity of 364,000 tons per year of contained nitrogen and a urea unit with annual nutrient capacity of 259,000 tons, began in 1979 at Abu Qir. The Talkha II project, consisting of an ammonia plant with annual nitrogen content capacity of 353,000 tons and a urea plant with 286,000 tons of nutrient capacity annually, should be onstream in 1980.~~ France.—An ammonia plant with annual contained nitrogen capacity of 300,000 tons was brought onstream in 1979 at the Grand Quevilly site of Rhone-Poulenc Industries, which will share the output with CdF Chimie and Cie. Francaise de l'Azote.~° Germany, Federal Republic of.—An ammonia plant jointly owned by Superfos A/S and Veba Chemie AG, rated at 496,000 tons per year of contained nitrogen, came onstream at Brünsbuttel in 1978.31 BASF will replace some older oil-based ammonia units at Ludwigshafen with a new natural-gas-fed plant having a nitrogen content capacity of 408,000 tons per year.32 Greece.—Plans to construct a 1,100-tonper-day ammonia plant at Kavalla by 1982 were announced.~~ India.—The government has decided to grant first priority to natural gas as a fertilizer feedstock, followed by coal and naphtha.34 The Fertilizer Corp. of India (FCI) brought a 900-ton-per-day, fuel-oil-based ammonia plant and downstream urea unit with a capacity of 167,000 tons of nutrient per year, onstream at Nangal early in 1978.~~ Two facilities utilizing coal as feedstock were completed at Talcher and Ramagundam for FCI in 1979, with annual capacities of 269,000 tons of contained nitrogen for the ammonia plants and 251,000 tons nitrogen content of urea.36 Modernization of FCI's complex at Sindri was completed in 1979, raising annual ammonia and urea capacities to 168,000 tons and 309,000 tons of nitrogen content, respectively.~~ The Gujarat State Fertilizer Corp. awarded a contract for the construction of a 1,485ton-per-day ammonia plant and a 1,765-tonper-day urea unit at Broach.38 A third nitrogen fertilizer facility will be constructed for Hindustan Fertilizer Corp. at Namrup by 1982. Gas from the Assam oilfields will be used as feedstock for a 180,000-ton-per-year-nitrogen ammonia plant and a 168,000-ton-per-year-nitrogen urea unit.~~ Indian Explosives Ltd. announced plans to expand its annual ammonia and urea
