- Factors Involved Affecting the Time and Cost of Running Polymer Membranes in Local Wastewater Treatment Plants at Institutional Level(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2023-11-24) Orduña Ávila, Enrique; Membrillo Hernández, Jorge; emimmayorquin; Ordoñez Díaz, José Antonio Benjamín; Fuentes Álvarez, José Rubé; Escuela de Ingeniería y Ciencias; Campus Ciudad de México; Bustamante Bello, Martín RogelioThis work presents the essential engineering, administrative, economic and environmental factors that must be taken into consideration for the implementation of a polymeric membrane in a local wastewater treatment plant, taking the wastewater treatment plant from the Mexico City Campus of the Tecnológico de Monterrey The factors analyzed remained in critical variables of the engineering project such as time and cost, allowing us to discern the main problems that membranes present in plants with lower effluent generation capacity compared to industrial membranes. The project shows the main criteria that must be considered to guarantee profitability through the scalability of certain factors; allowing the client who purchases the membranes to have adequate information about the panoramic scheme that involves the implementation of the polymeric membranes, and for the suppliers to have well-established criteria to consider local private institutions as future clients. despite the fact that the working conditions are very different from those of current clients such as large industries and municipal treatment plants.
- The energy use of the macroalga pelagic Sargassum in the Mexican Caribbean(Instituto Tecnológico y de Estudios Superiores de Monterrey) García Dorantes, José Gil; MEMBRILLO HERNANDEZ, JORGE; 21703; Membrillo Hernández, Jorge; puelquio, emipsanchez; Benjamín Ordóñez Díaz, José Antonio; Membrillo Hernández, Jorge; Ganem Corvera, Ricardo; Escuela de Ingeniería y Ciencias; Campus Ciudad de MéxicoThe potential of the pelagic Sargassum as feedstock for energy and substrates production is evaluated from an engineering point of view to determine if the macroalgae is a source of renewable biomass at a large-industrial level. This alternative could be a solution to mitigation and adaptation for the influx problem in the Caribbean coastline of Mexico (and other Caribbean countries). Recent research and experiments suggest that macroalgae can be processed by biorefinery systems like Hydrothermal Liquefaction (HTL) that makes suitable the use of the Pelagic Sargassum as a source of renewable energy and a substrate of potential products and services. Two different process scenarios, with or without a heat exchanger unit, are simulated in Aspen Plus to evaluate the physical, chemical, and cost feasibility of the macroalga continuous HTL to obtain bio-crude oil, an aqueous phase, gaseous phase, and char, as valuable products at an industrial production with a potential use such as biofuel, and fertilizer. Both cases are thermodynamically, energetically, and economically evaluated with a macroalga sludge feedstock of 2.79 M t/year, a total product sales of $14.94 M USD/year, and a payback period of 5.54 years in one of the scenarios considering the total capital, and utility costs of the integrated system and its boundaries. The production of 1.87 PJ/year of energy equates to 0.05% of Mexico's primary energy production from crude oil in 2019. This study stands for an opportunity for adaptation and mitigation of the problem that is affecting the Caribbean zone, as well as for an opportunity of synergy between the scientific, private, and government sectors.
