Process Engineering


Industrial process engineering is getting more complex with drivers for higher efficiencies, higher productivity, feedstock flexibility, reduced emissions, improved supply chains, cradle-to-grave analysis, improved environmental profiles, and lower total costs of ownership. Today’s process engineering has to go beyond the traditional methods, use a more holistic systems approach, and consider more cross-functional considerations than ever before.
