OREANDA-NEWS. It’s the first time GNS has had a period of 2 years between overhauls this year. Within thirty calendar days, the volumes of works on technical diagnosis, cleaning, inspection and repair of equipment and pipelines doubled. The ethylene and propylene production facilities underwent large-scale re-equipment.

The ethylene produced is used not only for the company’s own needs but is also widely used by various companies in Bashkortostan and Russia.

Besides, in shop No.56, new reactors are installed at the section of acetylene hydrogenation in ethane-ethylene fraction. Now there are six reactors installed instead of three: three in operation and three in reserve. The reactors are also charged with a high selective hydrogenation catalyst of a new grade. This will help to produce additional quantities of ethylene from acetylene.

-  By renovating this section, we boosted our production in one of its most problematic sectors, - said Igor Taratunin, Technical Director, Gazprom neftekhim Salavat. – New reactors will help to increase the ethane-ethylene fraction load onto the reactor section. Besides, the use of three hydrogenation layers will help to increase the hydrogenation process selectivity.

At present, the section is in operational mode. The company managed to reach steady high loads that are 1000 tons per day.   

For reference: Gazprom neftekhim Salavat is one of the largest oil refining and petrochemical complexes in Russia with a complete cycle of crude hydrocarbons processing. The range of products includes gasolines, diesel fuel, kerosene, other oil products, liquefied gases, butyl alcohols, plasticizers, polyethylene, polystyrene, ammonia, urea and other products.
