    The Innovene G process is set apart from other gas phase processes by the unique catalyst systems used and the proprietary design features of the polymerisation loop and post reactor degassing and treatment. The process enjoys C8, C6 and C4 co-monomer flexibility

    The process has low capital cost inherent of a low pressure, low temperature gas phase process. In addition, the exclusive Innovene cyclone technology removes the need for regular loop cleaning and reduces grade transition time. These combine to provide high on-stream times with high quality product yield giving Innovene G the overall lowest lifetime cost for any gas phase process.

    Using INcat Ziegler-Natta catalysts, products include narrow molecular weight resins suitable for blown and cast films, injection and rotational moulding, while INcat HPLL metallocence products included high performance LLDPE films. The process has produced over 150 different grades of products with a portfolio that is being continually expanded by units operated by INEOS as well as licensees of the technology.

    These same advances make debottlenecking existing smaller capacity plant both cheap and straightforward. There are examples of single reactor trains being rapidly expanded up to almost twice the original capacity. The unique Enhanced High Productivity process development allows cost effective expansion of all gas phase polyethylene processes.

  • Innovene™ S

    The Innovene S process is a simple and robust design enjoying best in class economics with low investment and operating costs. With no reactor fouling and hence no required cleaning, the process has proven high on-stream times.

Autothermal Cracking

  • Summary

    Autothermal CrackingAutothermal Cracking is a proprietary technology developed by INEOS Technologies for the manufacture of ethylene and propylene which offers lower investment cost (as much as 40% less,) less energy consumption and lower emissions than steam cracking.

    Through the use of a very fast (millisecond) oxidative thermal cracking catalyst large steam cracking furnaces are replaced by a number of small catalyst-charged reactors. Operation at elevated pressure removes the need for cracked gas compression and large steam generation systems as there is no need for steam feed to the autothermal cracking process.

    The autothermal cracking process has been proven at 5 t per day scale at Grangemouth with wide ranges of real feeds and a full commercial process design has been developed, including a detailed autothermal reactor design. Please contact us for more information.

  • Technology

    Many technical challenges have been addressed throughout the development of autothermal cracking, including:

    • Mixing fuel and pure oxygen over a wide range of pressures to achieve good mixing with minimum inventories, and deliver mixed feeds uniformly to the catalyst
    • Catalyst design to ensure mechanical robustness and chemical stability
    • Designing a commercial scale reactor which can safely handle the mechanical challenges of fast heating and cooling at pressures up to 30 barg
    • Rapid gas phase quenching, to avoid secondary products and boost olefin yields
    • Product purification, including detailed quench tower design

    Ethylene and propylene can be made from a wide range of feedstocks using autothermal cracking. We also have experience with feeds from vacuum residue to ethane. Lighter feeds allow access to elevated pressure operation.

    Autothermal cracking gives impressive emissions benefits, with a procees that almost completely eliminates the production of NOx. Our greenhouse gas footprint is also reduced by up to 40%, owing to a lower energy demand. 

    In contrast to steam cracking, unsaturated hydrocarbon streams may be fed to the autothermal reactor without pre-treatment, and without coke formation problems. This allows a wide range of low cost recycle stream options to be considered with an autothermal cracker.
