Any visitor to Asaluyeh will immediately notice the series of Gas and Petrochemical complexes running along the coast, one of the largest collection of such facilities in the world. The various plants and complexes currently run for some 12 km, and more are being constructed. A series of gas flares which line the facility are immediately obvious, including one enormous flare in particular, with flames of almost 100 m in height. This flare is visible far out to sea. The area also hosts the world's largest aromatic production plant, Noori Petrochemical Complex, with an annual capacity of 4.2 million tons. Once completed, South Pars development revenue will exceed current oil exports incomes.
