With facilities in Calgary and Joffre, Nova Chemicals manufactures chemicals, plastic resins, and end products while working to keep their environmental impact to an absolute minimum.

This energy efficiency project aimed to reduce GHG emissions by improving separation processes in ethylene manufacturing through innovative micro-porous molecular sieves that separate similar hydrocarbon molecules.

Current ethylene manufacturing gas separations consume energy to condense and boil hydrocarbon mixtures. Nova believed molecular sieves could reduce GHG emissions because energy consumed in molecular sieve separation is inherently lower.
