A top 25 chemical company operation was planning to expand and upgrade a plant that produced feedstock for an adjacent plant. Using the SIO approach, a team comprised of 5DN professionals and client operators discovered that the product spec delivered to the downstream process was not optimized. By re-defining the required spec, and addressing changes on both sides of this interface with much smaller capital requirements, the client avoided the costly multi-million dollar expansion and saved over $500,000 in energy costs per year.
