Now that I have too long played devil's advocate, I want to conclude on a very positive note. The fact is that chemical engineers today are using high performance computing, and computing at all levels, to break computational barriers and truly expand the frontiers of process engineering. For the chemical process industries, effective and appropriate use of computing technology has much to offer: cleaner, safer, more efficient and less costly manufacturing processes, new and better products, faster times to market, and faster responses to changes in economic, regulatory, and technological environments. This adds up to a bottom line of enhanced competitiveness in the global marketplace.
