Novolen Pp Novolen® Gas-Phase Process
Olefins are a class of chemicals such as ethylene, propylene & butylene. They are the building blocks for a products such as plastics, rubbers & solvents. Lummus Technology's Novolen® technology licenses the gas-phase polypropylene process worldwide on the basis of Ziegler-Natta and metallocene catalysts.

Due to the simplicity of the gas-phase process, the capital expenditures for inside battery limits ISBL of a Novolen technology process plant are the lowest in the industry.
This investment cost advantage for world-scale plants producing high value products further increases the attractiveness for investors.
The Novolen gas-phase process includes standardized packages for high-efficiency monomer recovery. Proven reliability and minimized equipment count lead to highly competitive maintenance costs.
Two identical reactors connected in a row allow for impact copolymer production and also for homopolymer production Exclusive vacuum degassing at extruder.
Products at the lowest edge of volatile content in the marketplace with very low taste and odor level for highly demanding applications for example, drinking water pipes and food packaging.
Can be combined with our exclusive desorber technology Simple, solvent-free gas-phase process. Read More. Spheripol Process — Polypropylene LyondellBasell's leading polypropylene technology, Spheripol , combines outstanding reliability and safety with leading operating and investment costs to provide advantaged economics to customers.

The mixture of polypropylene powder and non converted propylene is removed from the reactor. After the propylene is evaporated, it is sent to a series of separating containers where polymer degassing is finished.
EThe propylene that does not finished completing the polymerization reaction is condensed in a subsequent step and injected again into the reactor.
Polypropylene could not be traded after Polymerization stage since it degrades easily and needs different additives according to the application.
That process is done in this unit. The main equipment is the twin-screw extruder with KW motor power. The polypropylene powder is melted and mixed thoroughly with different additivies.
The melted material is extracted by a gear pump that forces them through a perforated plate where the polypropylene pellets take their final trade shape.
Some applications require a polymer with certain specific features, called Controlled Rheology. The distribution of molecular weight of chains is altered by cutting the long ones.
The technology enables very advanced tailoring of product properties to address specific application needs. Spherizone, Spheripol and Metocene are trademarks owned or used by LyondellBasell group companies.
We offer research, development and quality improvement of technology pertaining to new chemical processes in connection with production of polyolefins.
Nine of the top 10 worldwide producers place their trust in LyondellBasell licensed PP technologies.
Spherizone Process - High Performance PP The breakthrough Spherizone multi-zone circulating reactor provides a unique and innovative platform with flexible operating conditions to manufacture added-value polypropylene with novel architecture and enhanced properties.

The reaction itself is exothermic. Reactor cooling is achieved by evaporation of liquefied reactor gas, which is injected into the reactor. Flash evaporation of the liquid in the polymer bed ensures the most efficient heat removal.
The polymer powder is discharged from the reactor s and separated from the gas in a discharge cyclone at atmospheric pressure. Any unreacted monomer separated from the powder is compressed and either recycled or returned to the upstream olefins unit for recovery.
The final degassing of the polymer is done in a purge silo by flushing with nitrogen. The purge offgas is sent to a recovery system.
Finally, the powder is converted into pellets that incorporate a full range of well-dispersed additives. For highly demanding applications, which require extremely low levels for volatiles and odor, the gas-phase process offers an optional desorber unit to treat the pellets after extrusion.
Due to the simplicity of the gas-phase process, the capital expenditures for inside battery limits ISBL of a Novolen technology process plant are the lowest in the industry.It is the most common technology in modern polypropylene production plants.
