Urmia Petrochemical Company
Urmia petrochemical company (UPC) is located some 30 kilometers southwest of Urmia city and in the vicinity of the road connecting Urmia to mahabad. The complex has been built in a 220 hectares land of which 50 hectares is allocated for the industrial division and 170 hectares for waste water ponds and green space.National petrochemical company (NPC) owns the whole 220 hectare state. Urea, ammonia and sulphuric acid are the raw materials (feedstock) for the complex and the required raw water is supplied from two wells.
The complex has 3 process units for producing Sulfuric acid, crystal melamine and ammonia sulphate with utility and offsite units supplying water,steam,compressed air, nitrogen, and electricity and storage tanks.
The UPCconstruction began in 1991 and installation of the process equipment started in 1992 by the Iranian contractor. Construction and erection of the utility and offsite facilities began in September 1994 by Iranian
Contractors and with the completion of erection and precommissioning process, the complex went on stream in early 1995. The Urmia petrochemical complex was officially inaugurated in September 1995

Sulfuric Acid Uses
The major use (60% of total production worldwide) for sulfuric acid is in the “wet method” for the production of phosphoric acid, used for manufacture of phosphate fertilizers as well as trisodium phosphate for detergents. In this method, phosphate rock is used, and more than 100 million tones are processed annually. This raw material is shown below as fluorapatite, though the exact composition may vary. This is treated with 93% sulfuric acid to produce calcium sulfate, hydrogen fluoride (HF) and phosphoric acid. The HF is removed as hydrofluoric acid. The overall process can be represented as:
Ca5F(PO4)3 + 5 H2SO4 + 10 H2O → 5 CaSO4·2 H2O + HF + 3 H3PO4
Sulfuric acid is used in large quantities by the iron and steelmaking industry to remove oxidation, rust and scale from rolled sheet and billets prior to sale to the automobile and white goods (appliances) industry. Used acid is often recycled using a Spent Acid Regeneration (SAR) plant. These plants combust spent acid with natural gas, refinery gas, fuel oil or other fuel sources. This combustion process produces gaseous sulfur dioxide (SO2) and sulfur trioxide (SO3) which are then used to manufacture “new” sulfuric acid. SAR plants are common additions to metal smelting plants, oil refineries, and other industries where sulfuric acid is consumed in bulk, as operating a SAR plant is much cheaper than the recurring costs of spent acid disposal and new acid purchases.
Ammonium sulfate, an important nitrogen fertilizer, is most commonly produced as a byproduct from coking plants supplying the iron and steel making plants. Reacting the ammonia produced in the thermal decomposition of coal with waste sulfuric acid allows the ammonia to be crystallized out as a salt (often brown because of iron contamination) and sold into the agro-chemicals industry.
