Refiners must recognize the required organizational changes and use an efficient and cost-effective system design when upgrading an existing blending system to an advanced one. Part 1 of this series (OGJ, Feb. 14, 2005, p. 50) discussed the organizational changes required during an upgrade project that would lead to a sustained return on investment. This conclusion of the series addresses the second component of an upgrade project—the hardware and software required, and how to design and select an efficient and cost-effective advanced blend control system.
Both articles are based on a study conducted in a mid-sized refinery in North America.
