Prospective bidders include: Japan’s Kawasaki Heavy Industries (KHI), with the local Nargan; Italy’s Snamprogetti, so far without a local partner; and Japan’s Toyo Engineering Corporation, with Switzerland’s Ammonia Casaleand the local Petrochemical Industries Design & Engineering Company (PIDEC).

The new plant will have capacity of 670,000 tonnes a year (t/y) of ammonia and 1.1 million t/y of urea. Existing production from the two ammonia plants at the same complex is 477,000 t/y and 567,000 t/y from the two urea plants.

Earlier this year, a team of Toyo, PIDEC and Japan’s Chiyoda Corporationwon a $240 million contract for another ammonia/urea project at Assaluyeh. Fertiliser projects feature large in Iran’s petrochemical expansion plans.
