Shchekinoazot. Groundbreaking Ceremony for New Methanol-Ammonia Plant

Shchekinoazot site prepared for new construction

Summary • A methanol plant with a capacity of 1,350 MTPD and a hydrogen plant with a capacity of 26,000 Nm3/h have been constructed for Shchekinoazot, using Topsoe modern technologies • A new integrated methanol-ammonia plant with a capacity 1,350 MTPD of methanol and 415 MTPD of ammonia is currently under implementation at Shchekinoazot

• Due to the long-term partnership and excellent and open collaboration between the two companies, Shchekinoazot and Topsoe have jointly solved all problems which appeared in the first period of operation. The cooperation has resulted in construction and operation of the modern and highly efficient plants • Topsoe’s deep involvement in the Shchekinoazot site, together with a high extent of flexibility of Topsoe process solutions, allowed Topsoe to help Shchekinoazot achieve optimal performance by offering efficient integration between the processes units constructed in Shchekinoazot
