Gazprom advances hydrocarbon processing projects

Increased recovery of valuable components from raw hydrocarbons and output of readily marketable products were the company’s key objectives in the field of gas and liquid hydrocarbons processing. For these purposes, Gazprom both develops existing and builds new processing capacities.

In particular, the Surgut Condensate Stabilisation Plant’s annual capacity was raised from 8 million t to 12 million t in 2014 through the addition of two process trains. In 2015 – 2017, the Astrakhan gas processing plant (GPP) and Gazprom Neftekhim Salavat were upgraded in order to increase the quality and output of their products. In addition, an advanced natural gas and propylene processing complex was commissioned this year at Gazprom Neftekhim Salavat’s plant.

Several hydrocarbon processing projects of strategic importance are currently at the implementation stage. The Amur GPP, the largest natural gas processing facility in Russia, is under construction. The plant will process 42 billion m3/yr of multi-component gas from the Yakutia and Irkutsk gas production centres. Along with commercial gas, the GPP will produce helium, ethane, propane, butane and other components valuable for the petrochemical sector. The first two of the six process trains will become operational in 2021.

Gazprom plans to ramp up gas and gas condensate production from the Achimov and Valanginian deposits lying below the conventionally developed Cenomanian deposits at the fields of the Nadym-Pur-Taz region in the Yamal-Nenets Autonomous Area.

In order to process additional volumes of condensate from the Achimov deposits of the Nadym-Pur-Taz region, Gazprom is building a condensate stabilisation plant near Novy Urengoy. Designed for the production of stable condensate, natural gas liquids and de-ethanisation gas (with high content of ethane), the plant is slated to be commissioned in late 2019.

Such gas will be conveyed to a de-ethanisation gas treatment unit of the Urengoy condensate treatment plant. It is planned to bring the unit into operation in late 2019. The treated gas will be used as a feedstock for the Novy Urengoy gas chemical complex currently under construction. The complex will produce up to 400 000 tpy of polyethylene.

Gazprom is also studying the options of transmitting ethane gas from the Achimov and Valanginian deposits of the Nadym-Pur-Taz region and the Yamal Peninsula fields in order to process it in the Northwestern and Volga Federal districts.

In addition, the company is examining the expediency of setting up a gas chemical complex for ethane conversion into polymer products in the Astrakhan region. Ethane may be produced by the Astrakhan GPP after appropriate upgrading.
