Hydrocarbon Processing - May 2022 - 18

Circular Economy
purification is paramount, as contaminants could not only
jeopardize the operation of petrochemical steam cracker furnaces,
but can also leak and concentrate in downstream units,
ultimately ending up in polymers produced.
The successful commercialization of the purification technology
would not have been possible without the development
of new analysis methods by IFP Energies nouvelles to
properly assess the different qualities of pyrolysis oil. Pyrolysis
oil products concentrate a large proportion of multiple
contaminants, making it difficult to analyze through conventional
analysis methods.
As pyrolysis oil qualities vary substantially, the proprietary
purification processa has a unique flexibility (vs. conventional
hydroprocessing refining units) to cope with quality changes,
enabling it to continually guarantee production of on-specification
products suitable for direct undiluted processing in a
naphtha steam cracker. In addition to processing the full range
of pyrolysis oil, the proprietary purification processa
can also
embed a cracking option that will convert heavier products
back to virgin-equivalent recycled naphtha, maximizing the
closed-loop production of circular polymers.
Through its collaboration agreement with Plastic Energy,
the authors' company is also able to license patented, industrially
proven advanced recycling technology, which uses a thermal

the pyrolysis pathway for plastics recycling can play
an important role in mitigating the environmental impact of
plastic waste. It also unleashes the full potential of converting
any polyolefin plastic waste into food-grade quality.
At the onset of plastic recycling projects, the authors'
company's experts support project developers on questions
related to waste feedstocks characterization, technology performance,
costs and potential financing strategies, taking full
advantage of the unique expertise the company has built and
developed with partners in the field of chemical recycling.

NICOLAS MENET earned an engineering degree from Ecole
Des Mines de Nantes in France. He is also a functional safety
certified engineer and holds Lean and Six Sigma qualifications.
Mr. Menet has 20 yr of experience in the energy sector and
has focused on performance improvements in assets through
innovative processing technologies and digital solutions.
He now serves as the Development Manager for two plastics

THOMAS MALLET joined Axens in 2005 as Technology Manager
for biodiesel technologies. In 2008, he moved to the Olefins
Technology Group and has been involved in various technologies
aiming at upgrading light olefins from steam cracking and
fluid catalytic cracking such as etherification, heterogeneous
oligomerization and Atol (ethanol-to-ethylene). He joined
the Technology Development and Innovation Division in 2014,
