Sulzer GTC Technology has signed an agreement with SIBUR to provide its licensed pyrolysis gasoline (pygas) processing technologies, including design of the fractionation, first and second stage hydrotreating, aromatics extraction and thermal hydrodealkylation technologies for the modernisation of a benzene production facility at SIBUR’s Kstovo olefins production plant near Nizhniy Novgorod, Russia.
The modernised facility will serve as a hub for processing full range pygas from several SIBUR facilities, allow production of high-purity benzene with the lowest cash 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 modernising 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.”
