Lummus Novolen Technology GmbH (Novolen),
a part of CB&I, licenses the
Novolen® gas-phase polypropylene process worldwide
on the basis of Ziegler-Natta and metallocene catalysts
for the production of a full range of polypropylene resins
Integration Synergy
CB&I’s on-purpose technologies
for the production of polymer grade propylene,
such as
1.CATOFIN® dehydrogenation and
2.Olefins Conversions Technology (OCT)
allows licensors all over the world to benefit from
the synergies provided when combining those
in-house technologies with
Novolen’s polypropylene technology.
Simplified Novolen Process Schemes
The Novolen process utilizes
one or two identical vertical gas-phase stirred bed reactors.
Homopolymers and random copolymers
can be manufactured either
in a single reactor or in a reactor cascade with two reactors,
depending on the required capacity and product range.
Alternatively, two reactors can be operated
in parallel to achieve higher capacities
for a single train plant and to produce bimodal resins.
A cascade reactor configuration
is required for the production of impact copolymers,
whereas in the first reactor
a propylene homopolymer (or random copolymer) matrix
is polymerized and
in the second reactor the ethylene-propylene rubber (EPR)
is produced.
Independent from the configuration chosen,
all reactors are identical in design, size and material.
Parallel Configuration (Homo, Random)
Cascade Configuration (Homo, Random, Impact)
DETAILS
CB&I (NYSE:CBI)
today announced it has been awarded a contract by
Carbon Holdings
for the license and engineering design of a polypropylene unit
to be built in Ain Sokhna, Egypt.
The unit will be aligned to the Tahrir petrochemical complex
and use CB&I's Novolen® technology
to produce 350,000 metric tons per annum of polypropylene.
