Orenburg Gas Processing Plant, one of the largest in Russia, is located on the territory of the Orenburg gas condensate field. The first train of the plant was put into operation in 1974, and the second one in 1975. In 1978, the plant reached its maximum design capacity of 45 bln m3 of gas per year.
Since the start-up of its facilities, the plant processed over 1.3 trillion m3 of natural gas and over 70 mln tons of unstabilized condensate mixed with crude oil from the Orenburg oil and gas condensate field and other fields of Orenburg region. Since 1984, over 200 bln m3 of natural gas and about 70 mln tons of unstabilized gas condensate from the Karachaganak field were process at the plant.
