- Simulation of vacuum distillation unit in oil refinery: Operational strategies for optimal yield efficiency(MDPI, 2024-08-02) Muhammad, Shahrukh Atta; Haris, Khan; Muhammad, Ali; Rasikh, Tariq; Ahmed Usman, Yasir; Muhammad Mubashir, Iqbal; Sullah Ud, Din; Jaroslaw, Krzywanski; https://ror.org/040gykh71; https://ror.org/048g2sh07; https://ror.org/03ayjn504; https://ror.org/0566yhn94Oil refineries play a crucial role in meeting global energy demands, and optimizing the efficiency of critical processes is vital for economic feasibility and environmental sustainability. Simulation is an essential tool for the optimization of valuable products. This work presents the rigorous simulation of a vacuum distillation unit (VDU) based on actual data from the vacuum distillation processes using Aspen HYSYS V10. The Peng–Robinson fluid package is used in this simulation, and an input assay with a standard density of 29 API_60 (879.8 kg/m3) is employed. True boiling point (TBP) assay data are the type that is being used. Methane, ethane, propane, i-Butane, n-Butane, i-Pentane, and n-Pentane are the components listed in the simulation. The research determines that achieving a yield capacity of 685 tons/h requires thirty stages in the atmospheric distillation unit and twelve stages in the vacuum distillation unit while operating at 420 °C temperature and 9 kPa pressure. Adjustments in the flash section temperature (FST) and steam flow rate (SFR) are proposed to enhance operational efficiency. Increasing the FST from 370 °C to 400 °C and adjusting SFR from 10 tons/h to 26 tons/h increases the Light Vacuum Gas Oil (LVGO) yield by 7.2% while elevating the FST from 400 °C to 430 °C and adjusting SFR from 10 tons/h to 26 tons/h enhances the High Vacuum Gas Oil (HVGO) yield by 7.4%. These optimization strategies offer a practical and effective approach for refineries to improve the economic benefits of vacuum distillation units. The implications of this research can act as a computational thinking exercise for higher education students considering the case study where only through changing the operational strategies can the yield be enhanced by 10.81% in the vacuum distillation unit of the oil refinery.
- The Impact of Higher Education on Entrepreneurship and the Innovation Ecosystem: A Case Study in Mexico(MDPI, 2019-10-11) Portuguez Castro, May; Ross Scheede, Carlos; Gómez Zermeño, Marcela Georgina; Tecnológico de Monterrey; Center for Global Innovation and Entrepreneurship, The University of Texas at AustinEntrepreneurship is recognized as an engine for the economy. However, Latin America must promote higher opportunities for the creation of new businesses, especially for technology-based ventures. In this sense, the Center for Global Innovation and Entrepreneurship (CGIE) of the University of Texas at Austin offers a Master of Science in Technology Commercialization (MCCT) that prepares students with methodologies to promote the creation of new businesses in Mexico. This study aims to know the contribution of training to the creation of new companies, and its role in the innovation and the technology transfer processes, from the viewpoint of the participants. This research presents a case study that analyzes the impact of the MCCT through the analysis of the data of a survey answered by 109 former students of this center. Findings show that the methodologies developed by the MCCT allow the creation of technology-based enterprises and entrepreneurial skills in students. This study presents good practices that can be emulated by other countries in the region, as well as recognizing the great value the role of higher education in creating synergies between actors of the innovation ecosystem that strengthen social and economic growth.
