Abstract

See full text

A power generation system includes four heating fluid circuits thermally coupled to heat sources from sub-units of a petrochemical refining system. The sub-units include a hydrocracking plant, an aromatics plant, and a diesel hydro-treating plant. Subsets of the heat sources includes hydrocracking plant heat exchangers coupled to streams in the hydrocracking plant, aromatics plant heat exchangers coupled to streams in the aromatics plant, and diesel hydro-treating plant heat exchangers coupled to streams in the diesel hydro-treating plant. A power generation system includes three organic Rankine cycles, each including a working fluid that is thermally coupled to at least one heating fluid circuit to heat the working fluid, and an expander to generate electrical power from the heated working fluid. The system includes a control system to activate a set of control valves to selectively thermally couple each heating fluid circuit to at least a portion of the heat sources.
