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.
