thyssenkrupp alkoxylation plants are based on our proprietary Jet Reactor technology and has to date more than 1.8 million tonnes of annual capacity installed world-wide.  This success is based on class-leading safety, superior technology, superior performance, flexibility and value.

The core of the process is the Jet Mixer technology which ensures the highest reaction rates and hence minimum free EO/PO in both liquid and gas phases.

Major advantages of the thyssenkrupp Jet Reactor technology:

  • Inherent Safer Design concept is an intrinsic part of tkIS Oleochemical technology. Runaway prevention. Mechanical integrity. Self priming jet mixer

  • Performance of the Jet Mixer: Excellent gas-liquid mixing, highest contact surface and mass & energy transfer rates. High EO & PO conversion, high yields, shorter batch times

  • Automated batch sequence control and recipes, high accuracy measurements. Advanced control algorithms supported by pilot testing. Minimal operator requirement.

  • Consistent, predictable product quality. Lower catalyst loading. vapor recirculation leading to lowest residual oxide and 1,4 dioxane

  • Flexibility: High growth ratios. Wide range of starters. Multiple grades per train. Innovative design for minimal cross contamination and changeover time.

Jet Mixer

Our new Jet Mixer design ensures the highest reaction rates and hence minimum free EO/PO in both liquid and gas phases. Together with minimum gas volume, 45 barg design pressure, DCS/ESD and interlock systems, and our sophisticated control algorithm which maintains at all times inert gas phase conditions, our clients are always assured of the highest standards of process safety. The thyssenkrupp Jet Reactor system as applied to production of EO/PO derivatives offers far superior controllability, lower residual alkylene oxide levels, and faster reaction cycle times when compared with conventional stirred reactor designs.  

Configuration

Superior performance stems from our design approach which is driven foremost by our customers’ needs, and is tailored to make best use of available utilities and services. We can provide plant concepts ranging from a single reactor vessel; reactor plus pre-treatment; plus post-treatment; plus Economizer; plus filtration; or various combinations of these options which are available as ‘plug and play’ modules. Just how the process is configured depends on the range of products required, end-user quality requirements, utility costs and availability, and site factors.
