Commissioning works for the APCS system of the third gas separation unit of the Amur GPP are underway

October 20, 2021 11:06

Gas separation unit of the third train of Amur GPP is equipped with DCS, ESD and gas detection system. The whole complex is merged into a single unit control system. Information on process parameters will be sent into central control room of the Amur GPP and helium production complex.

For the moment the system is subject to loop testing, which is usually performed prior to functional tests. During the works around 3200 signal loops are going to be tested. The tests involve around 40 various specialists of Gazprom Pererabotka Blagoveshchensk, the owner of Amur GPP, NIPIGAS, the general contractor of Amur GPP, equipment vendors and other experts.

APCS is designed for 24/7 continuous work and is able to perform in automatic and automated modes without any presence of service personnel directly at the process equipment. All the parameters are to be tracked in central control room of the plant. Moreover, operators are granted with an ability to remotely control the actuating mechanisms with necessary process interlocks. The Amur GPP APCS is one of the most advanced control systems of Russian gas industry facilities.


Background

Construction of the Amur Gas Processing Plant in the area of Svobodny town, Amur Region, is has been underway since October 2015 and was commenced as part of the Eastern Gas Program of PJSC Gazprom. Its design processing capacity amounts to 42 billion cubic meters of natural gas annually. Amur GPP will annually produce around 38 million of cubic meters of purified methane fraction for supply to China on basis of a long-term contract, 2.4 million tons of ethane, 1.5 million tons of liquefied petroleum gas (LPG), and 200 thousand tons of pentane and hexane fraction. One of the main products of the Amur GPP is helium. Helium is extremely demanded by high-tech industries. Amur GPP is going to be the world's leader of helium production with its annual capacity of 60 million cubic meters of helium.

The Amur GPP project includes six process trains with annual capacity of 7 billion cubic meters each and three helium purification and liquefaction plants with capacity of 20 million cubic meters each. Phased startup of other lines of Amur GPP is aligned with development of PJSC Gazprom capacities in Yakutia and Irkutsk Region.
