Due to the simplicity of the gas-phase process, the capital expenditures Ocean Express inside battery limits ISBL of a Novolen technology process plant are the lowest in the industry. Reactor Novoline Online Paypal is achieved by the transfer of heat by the decompression flash of the mixture of liquified gas from the reactor with feeding currents. Catalysts and Equipment. A cascade reactor configuration is required for the production of impact copolymers, whereas in the first reactor a propylene homopolymer or Panda Managed Login copolymer matrix is polymerized and in the Top 10 Games On App Store reactor the ethylene-propylene rubber EPR is produced. The Novolen gas-phase process includes standardized packages for high-efficiency monomer recovery. The overall concept of the Coperion system not only ensures Paysafecard 50 Euro operational flexibility required and necessary Dortmund Vs Hamburger the licensor for the processability of a broad range of PP types, but also significantly extends the possible application window. Stuttgart, July — In a recent test series performed in its test lab at Stuttgart, Germany, Coperion together with the technology licensor Lummus Novolen Technology demonstrated the wide range of possible applications for the proven Coperion ZSK twin screw extruder series. Independent from the configuration chosen, all reactors are identical in design, size and material.

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.

This investment cost advantage for world-scale plants producing high value products further increases the attractiveness for investors.

Liquids evaporation in the polymer bed ensures the most efficient heat exchange. The polymer powder is discharged from the reactor s and separated in a discharge cyclone at atmospheric pressure.

Any unreacted comonomer is separated from the powder and compressed. It is then either recycled or returned to the upstream distillation unit for recovery.

The polymer is mixed with nitrogen in a purge silo in order to remove the residual propylene. The purge gas is recovered, the powder is transfered to the powder silos.

Finally, the powder is converted by extrusion into pellets that incorporate a full range of well-dispersed additives. The process begins with the removal of impurities in a series of machines since those impurities seriously affect the efficiency of the Polymerization catalyst.

Then, in a deetanizing column, light gases are removed, some of them also affecting the polymerization. A distillation column of plates separates the propylene from propane.

This column operates with Heat Pumps, with which high energy efficiency is obtained since a compressor removes the gases from top of the column and uses them to heat its bottom.

At the same time, the pressure in the column is reduced and, then, the separation is improved. After the separation, many guard beds avoid impurities to reach the Polymerization stage.

The heart of this unit is the reactor of stirred tank type which operates steadily. Ziegler Natta catalysts, fresh propylene and hydrogen are injected to it which adjusts the molecular weight of the distributed polymer.

The propylene polymerization releases heat that is removed by boiling and condensing the propylene with water.

Metallocene Technology. Any un reacted monomer separated from the powder is compressed and either recycled or returned to the upstream olefins unit for recovery.

The polymer is flushed with nitrogen in a purge vessel to strip it of residual propylene. The purge vessel off gas is passed to a recovery system; the powder is transported to powder silos and is then converted into pellets that incorporate a full range of well-dispersed additives.

For highly demanding applications requiring extremely low volatiles and odor levels, the pellets are conveyed to degassing unit to treat the pellets after extrusion.

Overview Polypropylene is among the fastest growing polymers much of this growth is attributed to polypropylene's ability to displace conventional material wood, glass, metal and other thermoplastics at lower cost.

Advantages Produces full range of homo-polymers, random and impact copolymers in only two reactors with a selection of catalyst: Exceptional lot-to-lot and within-lot uniformity.

Exclusive pellet degassing. Simple, gas-phase, solvent-free process. Small reactor volume minimizes reactor residence time.

Performance Characteristics The Novolen polypropylene process utilizes one or two vertical, stirred bed, gas-phase reactors. Homo-polymers and random co-polymers can be manufactured either in a single reactor or in a reactor cascade with two reactors, depending on the required capacity and product range.

At this stage, propylene granules are formed around the catalyst particles. 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.
