Atol

Atol® - An innovative technology for bio-ethylene production through bio-ethanol dehydration

 

Profitable polymer grade bio-ethylene

Atol® is a technology for the most profitable production of polymer grade bio-ethylene by dehydration of 1st and/or 2nd generation renewable ethanol.

The bio-ethylene produced can be integrated in partial and/or total replacement of fossil hydrocarbon based ethylene in various downstream polymerization installations without requiring modifications.
Atol® bio-ethylene can therefore be fed into existing or new units of, for instance, polyethylene (PE), ethylene oxide/ethylene glycol (polyethylene-terephthalate (PET), polyolefins, alpha-olefins production for linear alkylbenzene (LABs) and polyalphaolefins (PAOs), benzene alkylation for polystyrene (PS), acrylonitrile-butadienestyrene (ABS), polyvinylchloride (PVC), etc.

Energy saving has been the key driver for Atol®’s process development with the objective to minimize operating costs and carbon foot-print. As a result of its innovative and patented thermal integration, Atol® utility consumption is minimized.

 

Atol® performance

  • 99+% ethanol per pass conversion
  • Close to stoechiometrical ethylene yield
  • Bio-ethylene purity: up to polymer grade 99.9+%
