Catalyst changes, downstream improvements increase FCC propylene yields

10/04/2004
Higher propylene yields from FCC units require higher reactor temperature and changes in the catalyst system. It is important that the plant operator concurrently evaluate reactor yields, wet-gas compressor, and gas-plant performance to determine the most cost-effective revamp strategy.Saudi Arabian Oil Co. (Saudi Aramco) evaluated four reactor case studies to determine the effect of different high-propylene-yield catalyst formulations on downstream equipment.Propylene is one of the fastest growing petrochemical feedstocks. Projected to exceed traditional supply from steam crackers, worldwide demand is forecast to increase 6 %/year during the next 20 years, due mainly to a growing need fo...
