LNG Storage System in Karagay District, the Perm Region
Gazprom Promgaz OJSC favorable review has been received.
Three first settlements (Ilyinskiy, Nerdva and Severniy Kommunar) in the Perm Territory to which natural gas will be supplied using LNG technology without use of cross-country gas pipelines have been selected in the scope of implementation of Remote Regions Gasification Program.
Karagay municipal district is located on the west of the Perm Territory in Obva (midstream) and Nerdva river basin. It extends from the north to the south at 90 km and from the west to the east at 45 km.
Administratively the area of the liquefied natural gas intake, storage and regasification facility (LNG ISRS) is located at the site near Nerdva village, Karagay district, the Perm Territory.
The district borders Nytvenskoe village at the south-east, Vereschaginskoe village at the south-west, Komi-Permyatski Autonomous District at the north and Ilyinskiy administrative area at the east. The distance from Karagay village to Mendeleevo station is 12 km; the distance to Kudymkar town is 89 km. The distance to the administrative center of the region, Perm, is 110 km.
The built "LNG Storage and Regasification System in Karagay District of the Perm Territory" (LNG ISRS) complex is a part of unified technologically interconnected system for liquefaction, storage, transportation and regasification of LNG in the Perm Territory.
LNG ISRS installation is designated for LNG intake via discharge unit from refuelling truck, its long-term storage with minimum losses, regasification and subsequent supply to consumers' gas networks.
The created LNG ISRS in terms of its technology and solutions is similar to the one built in Ilyinskiy district. It is made to increase reliability and unification of solutions and that allows operating and maintaining using minimum number of personnel and equipment.
LNG ISRS consists of two LNG intake, storage and supply tanks of capacity 20 m3 each and two parallel sets of atmospheric vaporizers of capacity 500 nm3/hour each.
The equipment operation is automated to the maximum. Connection of a filling truck to LNG discharge unit is performed manually only. Information on condition and parameters of equipment operation is transmitted both to a local control point and to the Control Room of LNG Plant. That guarantees timeliness of gas supply and safety of the complex operation.
Natural gas meeting GOST 5542-87 and fed to medium pressure pipeline for distribution to consumers of nearby settlement including private houses and municipal boiler plants is at the production site outlet.
