Petroleum refining processes are very energy-intensive, often requiring large amounts of power and process heat. A new DOE publication, Energy and Environmental Profile of the U.S. Petroleum Refining Industry, estimates process energy use and the contribution to overall refinery energy use, based on average values for a number of technologies. Actual energy consumption can vary considerably between various technologies. In addition, capacity utilization varies monthly, and over the last year has ranged from 90% to over 96%, according to DOE's report. The most energy-intensive refining processes are ethers manufacture, alkylation and C4 (butylene) isomerization. Most isobuty
