CB&I was awarded a lump sum turnkey contract by Snamprogetti to design and build two refrigerated ammonia storage tanks for the Qatar Fertilizer Company (QAFCO) 5 ammonia and urea expansion project in Mesaieed, Qatar. These are the currently the largest ammonia tanks in the world. QAFCO is expanding its existing fertilizer plant to increase its production of ammonia and urea.
