Abstract

The fourth in a series, this publication covers the 1991 data from API's annual survey of the types and amounts of residual materials generated and managed by the refining industry. In 1991, the industry generated 14.8 million wet tons of residual materials; the smallest quantity generated since API began this collection effort in 1987. The industry also reported that pollution prevention activities accounted for a reduction in 715,000 wet tons of materials. A trend analysis performed on the last five years of data was conducted also. This report can be used by oil companies to compare their residual generation and management practices with the rest of the industry.
