Item Diseño mecánico de una planta de extracción de co2 supercrítico para la obtención de fitocannabionoides a partir de biomasa de cannabis no psicoactivo.(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2023-03) García Núñez, Daniel Andrés; Arroba Arroba, César HernánThis project resolved the need to design the equipment for the extraction of supercritical fluids, in order to provide support to industries that choose to acquire this type of equipment abroad at very high costs. By means of the use of ASME codes and standards section VIII div 1 and div 2 used in Mechanical Engineering and used in this project, allowed the mechanical dimensioning of the extractor, collector and separator tanks. By means of CAD modeling, each tank was geometrically dimensioned taking into account the requirements of the production levels, and the resistance of each tank under operating conditions was also evaluated through simulation. At the end of the design and simulation of the extractor tanks, it was found that each one of them withstands the assigned design pressure with total safety, with the use of Super Duplex 2507 Stainless Steel and 316L steel that ensure the resistance and integrity of the tanks subjected to high pressures.Item Diseño de un intercambiador de calor de coraza y tubos para el aprovechamiento de gases residuales de una caldera de 125 BHP de potencia para la empresa GN. Industrial en la provincia de Tungurahua cantón Ambato(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2021-09) Martínez Ochoa, Oscar Maximiliano; Cabrera Anda, Santiago PaúlThe proposed objectives include: the design of a tube and shell exchanger for the use of waste gases from a 125 BHP power boiler for the GN INDUSTRIAL company. the characteristic parameters of the shell and pipe heat exchanger were determined, as well as the appropriate materials were selected for its correct operation, thermal analysis was carried out using software to determine the behavior of the fluids. The LMDT and NUT methods were used for thermal design. For the mechanical design, the ASME section VIII recommendations and the TEMA regulation were considered, which standardizes certain criteria for the design through the finite element method with the help of software, thermal and mechanical analysis of the heat exchanger was carried out with the following results: Thermal power of 25.53 kilowatts, heat transfer area of 5.75 square meters, efficiency of 37 percent, presenting as water outlet temperature of 29 degrees centigrade and the exhaust gas outlet temperature of 190 degrees centigrade the same one that has 24 two pass Cedula 40 tubes with a length of 1.5 meters and a shell of 600 millimeters in diameter and a total length of the heat exchanger of 2.13 meters with a weight of 645 kilograms, same that meets the thermal, hydraulic and mechanical requirements for the recovery of heat from the exhaust gases of the boiler for which it is being designed.
