Title: POWER GENERATION FROM WASTE HEAT IN INTEGRATED CRUDE OIL DIESEL HYDROTREATING AND AROMATICS FACILITIES
Abstract:
A power generation system includes two heating fluid circuits coupled to multiple heat sources from multiple sub-units of a petrochemical refining system. The sub-units include an integrated diesel hydro-treating plant and aromatics plant. A first subset and a second subset of the heat sources includes diesel hydro-treating plant heat exchangers coupled to streams in the diesel hydro-treating plant and aromatics plant heat exchangers coupled to streams in the aromatics plant, respectively. A power generation system includes an organic Rankine cycle (ORC) including a working fluid that is thermally coupled to the two heating fluid circuits 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.
