Patent number: 10961873Abstract: Optimizing power generation from waste heat in large industrial facilities such as petroleum refineries by utilizing a subset of all available hot source streams selected based, in part, on considerations for example, capital cost, ease of operation, economics of scale power generation, a number of ORC machines to be operated, operating conditions of each ORC machine, combinations of them, or other considerations are described. Recognizing that several subsets of hot sources can be identified from among the available hot sources in a large petroleum refinery, subsets of hot sources that are optimized to provide waste heat to one or more ORC machines for power generation are also described.Type: GrantFiled: September 28, 2017Date of Patent: March 30, 2021Assignee: Saudi Arabian Oil CompanyInventors: Mahmoud Bahy Mahmoud Noureldin, Hani Mohammed Al Saed, Ahmad Saleh Bunaiyan

Patent number: 9816759Abstract: 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.Type: GrantFiled: March 31, 2016Date of Patent: November 14, 2017Assignee: Saudi Arabian Oil CompanyInventors: Mahmoud Bahy Mahmoud Noureldin, Hani Mohammed Al Saed, Ahmad Saleh Bunaiyan
