PJSC Gazprom and its affiliates have started construction on a previously announced combined gas processing, liquefaction, and chemical complex at the Gulf of Finland near the seaport of Ust-Luga, Leningrad Oblast, Russia (OGJ Online, June 10, 2020). Construction activities on the proposed complex for processing ethane-containing gas (CPECG) began on May 21 and will cover works on the CPECG’s two major enterprises, including RusKhimAlyans’—a 50-50 special purpose venture of Gazprom and RusGazDobycha—integrated natural gas processing and liquefaction complex (GPC of the CPECG), as well as RusGazDobycha subsidiary Baltic Chemical Complex LLC’s (BCC) planned ethane-cracking complex, or gas chemical complex (GCC of the CPECG), Gazprom said. RusKhimAlyans GPC, which will have 13 million-tonnes/year liquefaction capacity, initially will receive 45 billion cu m/year (bcmy) of wet natural gas feedstock from Gazprom’s Achimov and Valanginian deposits in the NadymPur-Taz region of the Yamal Peninsula, and later, from specially allocated ethane gas pipelines delivering production from the region’s yet-to-be-developed Tambeyskoye field, the peninsula’s richest, according to Gazprom. The GPC will produce as much as 4 million tpy of ethane, and more than 2.2 million tpy of LPG, with ethane from the complex to feed nearby BCC’s proposed $13-billion ethane cracking project that—once in operation—will produce more than 3 million tpy of polymers (OGJ Online, Nov. 9, 2020). About 18 bcmy of gas remaining after processing at GPC—including ethane extraction, LPG, and 13 million tpy of LNG—will be exported from the site via Gazprom’s gas transmission lines (OGJ Online, Mar. 29, 2021).
