Petroleum Coke: A Viable Fuel for Cogeneration
MetadataShow full item record
Petroleum coke is a by-product of the coking process which upgrades (converts) low-valued residual oils into higher-valued transportation, heating and industrial fuels. Pace forecasts that by the year 2000 petroleum coke production will increase from 36 million to 47 million short tons/year. Because the crude pool will continue to become more sour and refiners treat the coker as the "garbage can" the quality of the petroleum cokes will generally degrade- contain higher sulfur and trace metal levels. The U.S. produces nearly 70% of the total and is expected to maintain this share. Domestic markets consumed less than half of the U.S. production; 80% of the high sulfur fuel grade production from the Gulf coast is exported to Japan or Europe. Increasing environmental concerns could disrupt historic markets and threaten coker operations. This would create opportunities for alternate end-uses such as cogeneration projects. The Pace Consultants Inc. continuously monitors and reports on the petroleum coke industry-production and markets-in its multi-client publication The Pace Petroleum Coke Ouarterly. The information presented in this paper is based on this involvement and Pace's experience in single and multi client consulting activities related to the petroleum refining and petroleum coke industries. The purpose is to provide a review of the existing world petroleum coke industry with particular emphasis on the U.S. production and markets. Forecasted production levels and critical factors which could alter the historic market disposition of petroleum coke are addressed.
