Norner has the competence to design and build your advanced laboratory reactors.

Bench scale reactors and reactor design

Bench scale reactors and reactor design

  • Based on our 40 year’s experience in polymerisation field, we offer to design, engineering and start-up bench scale olefin polymerisation reactor setups.
  • The reactor sizes can vary from small scale (0,2 l) to pilot size reactors (ca 20 l).
  • Alternatively, we can design and rebuild old, existing reactor systems to be more safe and controllable.
  • Training is also part of our services.

The design and set up of bench scale reactors include

  • Multi-step reactors for bulk, slurry and gas-phase conditions.
  • Reactor sizes from 0,2 to 20 liters.
  • Separate flash-tanks can be included (for vaporization of solvents); used especially in connection with bigger reactors.
  • Reactors can be built either for batch or semi-continuous operation (continuous/batch feeding of monomer, comonomer and hydrogen; solvent and polymer output as batch).
  • Fully automated reactors including automatic stop and vent off at dedicated time and/or accumulated flows.
  • Temperature control system for fast start-up and precise control.
  • Process control system.
  • We are using e.g. InTouch by Wonderware and LabVIEW.
  • The system can also be chosen according to customer needs.

Output from the system

  • The process control overview updated at preferred intervals.
  • Data collection (pressures, temperatures, feeds, accumulated flows, etc.).
  • Trend curves.
  • Gas transport in pipelines (chemically cleaned tubes - stainless steel, min. 200 bars) from the storage tanks include sophisticated inline purifiers to remove impurities (CO, CO2, H2O, COS, H2S, etc.) down to ppb level.
  • Pressure supply feeding system with low and precise flows of flammable liquids and gases.


  • Automatic safety arrangements like automatic stop and vent off from head-space at unsafe conditions predicted by software controlled from PLS and/or independent systems.
  • Explosion (EX) proof equipments, if required.
  • Safety evaluation and HAZOP studies are included.
  • Explosion walls or roof designed and built to take care of unexpected explosion.
  • On-line control of hydrocarbon and oxygen concentrations in all reactor rooms with an automatic link to safety system.
  • Safety arrangements are made according to national standards of the present site.
  • Training on safety will be done according to customer needs.
  • Training is included (will be done according to customer needs), also connected to the polymerizations done in the start-up.

Our services include

  • Consultation on polyolefin & other hydrocarbon-based bench scale reactor setups.
  • Trouble shooting of existing laboratory, pilot and commercial reactors (including products), at any customer in polyolefin field.
