Sulzer GTC Technology has signed an agreement with JSC SIBUR-Neftehim (SIBUR) to provide its licensed pyrolysis gasoline (pygas) processing technologies. This includes design of the fractionation, first and second stage hydrotreating, aromatics extraction and thermal hydrodealkylation technologies. The system is intended to modernize gasoline production at SIBUR’s Kstovo olefins plant near Nizhniy Novgorod, Russia.

The modernized facility will serve as a hub for processing full range pygas from several SIBUR facilities, allow production of high-purity gasoline at low cost, and recover non-aromatics to be used as cracker feed. Sulzer GTC will design a new GT-BTX® unit as well as revamp the existing pygas fractionation; first and second stage hydrotreating; and the thermal hydrodealkylation unit to process additional feed. Scope of supply includes the basic engineering package, technical services, proprietary catalyst, solvent and equipment.

“We are pleased to work with such a prestigious company as SIBUR to provide effective solutions for producing aromatics from pyrolysis gasoline and modernizing olefins production complexes,” said Ilya L. Aranovich, Sulzer GTC Director of Licensing for North America, Europe, and CIS Countries. He added, “We are excited to extend our track record of providing leading-edge solutions to improve the economics of naphtha-based crackers for clients in the CIS region and around the world.”

Sulzer GTC Technology, based in Houston, Texas, is a global licensor of refinery and petrochemical process technologies that offer a variety of approaches for managing aromatics and other high value-added molecules in petrochemical complexes. These technologies include the GT-BTX® Extractive Distillation process for recovery of aromatics; GT-Styrene® Extractive Distillation process for recovery of styrene monomer; GT-C5SM Extractive Distillation process for recovery of isoprene, piperylenes and DCPD; GT-TolAlkSM/GT-TransAlkSM – alkylation/transalkylation of toluene to produce mixed xylenes, and others.

JSC SIBUR-Neftehim (SIBUR), is a subsidiary of PJSC SIBUR Holding – the largest integrated petrochemicals company in Russia. SIBUR operates 26 production sites across Russia and has 27,000 employees. SIBUR serves more than 1,400 companies in the energy, chemical, consumer, construction, automotive and other industries in approximately 75 countries.
