Energy-efficient vacuum systems

Abstract

Vacuum technology is used in petroleum refineries to facilitate the distillation of heavy ends at low temperatures, to prevent coking and degradation of products and for other applications. A discussion on various methods for developing energy-efficiency vacuum generation systems in petroleum refineries covers studies to enhance understanding in the selection process; design principles and utility requirements; design strategy for a new vacuum system; optimization of vacuum system operating cost; equipment costs; and analysis of results.
