Propylene and Butylene Selective Light Olefin Additives
Refineries value LPG olefin streams differently, with some favoring C4=s, others favoring C3=, and others just plain want to maximize all. Grace® Light Olefin additive portfolio includes additives that are more selective towards butylene such as GBA-1™ or propylene such as OlefinsUltra® family of additives and our latest innovation, ZAVANTI™ next generation, max propylene yield additive.
Continuous vs. Opportunistic LPG Olefin Use
Depending on refinery strategy, the FCC may continuously maximize LPG olefins or may do so only when short term market conditions indicate light olefin yields should be maximized. Grace additives are available in a variety of packaging (bulk container, pre-blending with base catalyst, flow bins, super sacks, drums) to accommodate the needs of refineries of all sizes and objectives.
Industry Leading Expertise
Grace commercialized the first light olefin and octane enhancement additive in collaboration with Mobil in 1984. Throughout the years, we have developed and fine-tuned yield prediction and base loading models to support refineries. Are you a refinery that continuously maximizes C3= from a high severity FCC and is interested in increasing C3= yields further? Or are you a refinery with limited experience with Light Olefin additives? Grace additives are backed by the many years of experience of our team and we can help you decide on the right additive and additive usage rate to deliver maximum profitability to your refinery.
