Trigeneration: an alternative for energy savings

The design of new processes focused towards a more efficient use of energy, is nowadays highly desirable. In this paper, the design of a systemof trigeneration is presented as an alternative way of improved energy use in cogeneration systems. Savings are observed by the decrease of the fuel fed to the turbogeneration equipment. A regenerative-cycle cogeneration system and a new trigeneration systemwere studied, showing their benefits as well as the operation criteria for both processes.
