ing documentation, and then move on to
the active phase of construction.
Target capacity of the project is
50,000 tons of product per year. The EP
contractor for the project is NIPIGAZ,
which develops design and working
documentation and manages supplies
for the project.
The development of its own technolo-
gy for the production of hexene has been
carried out over the past few years by
SIBUR’s R&D centers – NIOST and
Polylab. Piloting on laboratory equip-
ment was successful.
Hexene is an intermediate for the
production of base polymers and other
petrochemical products. It is used in the
