Abstract
In a chemical processing plant such as a petroleum refinery, provision is made for steam boilers and heating furnaces in which the energy consumed by the boilers for generating steam exceeds the energy consumed by the heating furnaces. The steam is produced at a pressure level which is sufficient to operate at least one back-pressure turbo-alternator, then to heat the chemical process stream to a sufficiently high temperature by heat exchange with the steam recovered at the outlet of the turbo-alternator.
