BCT layout principle

Depending on the complexity of your request, we offer you a one, two or even three pot system. The three pot system consists of:

  • The Pre-Treatment section where catalyst and raw material are prepared and conditioned and the dehydration takes place.
  • The Reaction section where the production takes place with growth rate up to 1:85 in one single run.
  • The Post-treatment section where, if necessary, neutralisation, blending and bleaching is done.

Productivity / Efficiency
The BCT-Loop Reactor technology is characterised by

  • very high ethylene oxide dosing rates (> 1000 kg/hr/m3)
  • growth ratio up to 1:85 (starting volume : end volume) in one single shot
  • short cook-down times
  • high throughput

This results in remarkably reduced operational costs.

Safety Philosophy
Your safety is our MUST. Therefore our technology follows the Inherently Safe Design guidelines to eliminate potential risks during all production phases. There are intrinsic levels of safeguards such as:

  • elimination of possible ignition sources (e.g. no rotating parts in the gas phase)
  • inert conditions during all phases of the reactions
  • deflagration-proof plant desig

Product Quality
Using the Buss Alkoxylation technology you reach a constant product quality without stripping

  • EO content:           Typically < 1 ppm in the product
  • Dioxane content:  Typically < 3 ppm in AEOs and < 10 ppm in NPEs 
  • Colour:                  Typically < 10 APHA in AEOs (1-9 EO) and 10.... 20 APHA in PEG and MPEG
