Abstract

     Due to the increased use of coal and the reduced demand for Bunker C and other heavy liquid fuels, more refiners are adding
or increasing the capacity of their facilities for converting the bottom-of-the-barrel streams into more desirable products. Also many of today's crudes are heavier and contain.more sulfur and metals than crudes available five or ten years ago and therefore are available at a lower cost than lighter crudes.

    Most of these heavier crudes require either the addition of hydrogen or the removal of carbon to make more desirable products out of them. Both kinds of these processes require relatively large amounts of energy compared to simple distillation.

     Energy conservation measures are required to make these processes efficient and hence more economical.

     The technology of conserving energy and the use of cogeneration in bottom-of-the-barrel processes are discussed in this paper. The selection of the best combination of process scheme and energy recovery techniques importantly influences the return-On-investment for such plants.

Introduction.

     The success of the energy conservation programs durin~ the last i0 yeaFs has been truly phenomenal. In fact this 1982 meeting in Houston, Texas is particularly significant in that most benchmarks for the progress of energy conservation are related to the energy being used by similar facilities just
ten year a~o. Houston and Texas industries can be proud of their leadership in the application of energy conservation
