The complex, at Assalouyeh on the Gulf coast, completes the first part of a two-phase scheme to build two fertiliser production lines, each with a capacity of 340,000 tonnes a year (t/y) of ammonia and 500,000 t/y of urea.
The second half of the scheme is set to be completed by March 2008. The project is part of the Pars Special Economic Energy Zone, which became operational in March.
The country’s current fertiliser output comes from the Shiraz plant, which has a 432,000-t/y ammonia line and a 543,000-t/y urea line, and the Razi complex, which produces 318,000-t/y of urea and about 1 million t/y of ammonia.
