Oman India Fertiliser Company SAOC (OMIFCO) has been established, as the result of an initiative by the Governments of Oman & India, in order to construct, own and operate a modern world scale two-train ammonia-urea fertiliser manufacturing plant at the Sur Industrial Estate in the Sultanate of Oman. OMIFCO is owned 50% by Oman Oil Company SAOC (OOC), 25% by Indian Farmers Fertiliser Cooperative Limited (IFFCO) & 25% by Krishak Bharati Cooperative Limited (KRIBHCO). The plant has the capacity to produce 1,750 T/D of Anhydrous Ammonia from 2 Ammonia Plants and 2,530 T/D of granular urea from 2 Urea Plants.

OMIFCO considers the issue of reducing the environmental impacts resulting from its operations as its top priority along with the promotion of production to raise the national economy.

As a commitment to continuous improvement in productivity & environment, OMIFCO has been awarded ISO-9001:2000 certification by BVQI since June '2008 for its Quality Management System.

The prime function of the complex is to produce ammonia and urea. This grass-root project consists of an Ammonia/ Urea fertilizer complex, together with all utility and off-site facilities (including the marine facilities) necessary to make the complex completely self-sufficient during construction or under any operational mode, without back-up facilities from any other source.

OMIFCO Fertilizer Complex has two Streams of Ammonia Plant and two Streams of Urea Plant. Annual capacity for Urea and Ammonia is 1.652 million MT and 1.15 million MT respectively. This project was built at a total cost of US$ 960 million.

The trial production commenced from plant one in March, 2005 and within a very short time of two months, the entire complex was commissioned and commercial production commenced from 14th July.

Ammonia Plants

OMIFCO fertilizer complex has two Ammonia plants, designed by Haldor Topsoe.

Ammonia is a chemical comprising of nitrogen and hydrogen. It is designated in chemical notation as NH3. Ammonia is extremely soluble in water and is frequently used as a water solution called aqua ammonia. Ammonia chemically combines with water to form

Ammonium hydroxide. OMIFCO produces anhydrous ammonia which is essentially pure (over 99 percent) ammonia."Anhydrous" is a Greek word meaning "without water;" therefore, anhydrous ammonia in ammonia without water.

Refrigerant grade anhydrous ammonia is a clear, colorless liquid or gas, free from visible impurities. It is at least 99.95 percent pure ammonia. Water content be above 33 parts per million (ppm) and oil cannot have a content above 2 ppm. Preserving the purity of the ammonia is essential to ensure proper function of the refrigeration system.

2 Ammonia Plants, 1750 T/D capacity, Halder Topso Technology (which includes CO2 removal licensed by Giammarco Vetrocoke) are installed at OMIFCO.

Urea Plants

Urea is a white crystalline substance with the chemical formula CO(NH2)2; it is highly water soluble and contains 46% nitrogen. Urea is considered an organic compound because it contains carbon. It was the first organic compound every synthesized by chemists; this was accomplished in the early 1800s by German chemists. Urea is made by reacting carbon dioxide (CO2) with anhydrous ammonia (NH3) under 3,000 psi pressures and at 350 degrees F.

The removal of water that occurs during the reaction is referred to as "dehydration." The resulting molten mixture is further processed into either prills or granules. Urea is the major fertilizer traded in international commerce. In the very near future urea is expected to account for more than 50% of the nitrogen fertilizer in world trade.

When compared to other dry fertilizers, urea has captured more than 65% of the world trade.

Urea has a number of advantages over other nitrogen fertilizers. Urea is safe to ship and handle, it is less corrosive to equipment, it has a higher analysis than any other dry nitrogen fertilizer and it can beused on virtually all crops. Urea can be stored and distributed through conventional systems. It can be applied in many different ways from sophisticated aerial application equipment to a farm spreading urea by hand. Urea is also highly water soluble so it moves readily into the soil. The high analysis means a reduced transportation and application cost per pound of nitrogen.

2 Granulated Urea Plants, 2530 T/D capacity, Snamprogetti Technology (Urea Synthesis) and Hydro Fertilizer Technology (granulation) are installed at OMIFCO.
