Low Level Waste Heat Conversion by Organic Rankine Cycle. Task 2B Report

摘要

A Refinery Energy Profile Study identified the waste heat being rejected from process streams in air and water cooled heat exchangers as a potential area for the application of energy conservation technology. One technology for recovering energy in this area, when process stream temperatures are in the 200 to 400 exp 0 F range, is the Organic Rankine Cycle (ORC) System. The Rankine cycle is a thermodynamic process for converting heat energy into mechanical and/or electrical energy. The objective of Task 2B in this followup contract to the Profile Study is to evaluate ORC systems for recovering energy from air and water cooled process streams by analyzing specific applications within a refinery crude unit. The basis for this study is the data from the Refinery Energy Profile Study. (ERA citation 10:048969)
