- PublicaciónAcceso abiertoDiseño conceptual de un sistema de separación (knockout drum) para la prevención de fallas por arrastre de líquido en compresores de gas(2018-10-03) Imitola Buelvas, Andrés Alfonso; Cueto Castro, Steven; Matute Thowinson, AdalbertoIn the present work, the design of a two-phase separation system (gas-liq) is carried out in a Diesel hydrotreating unit in Cartagena, with the central equipment being the knock out drum (KNO). The KNO is a device used in several industrial applications to separate vapor-liq phases, whose main objective will be to avoid the dragging of liquids to a compressor of the process. Which, is responsible for sending the sulfuric acid-free hydrogen to other sections where required. To achieve the proposed objective, initially the operational information of the teams involved in the process was collected, such as the gas stripping device, the rich amine drum and the compressor already mentioned above. Subsequently, a sequence of calculations was established for the design of the gasliq separator where parameters such as the compressibility factor, viscosity and gas capacity, critical speed and settling speed, nozzle diameter of the inlet, liquid capacity among others intervened. factors necessary for the proper sizing of the equipment. Finally, an economic analysis was carried out to know the viability of the project. It was implemented when the initial investment started compared to the United States. Ultimately, the compressor failure only represents 0.12% of the cost of repairs and the cost of production for the stops required in this time...
- PublicaciónAcceso abiertoDiseño y simulación de una torre de destilación para la recuperación de condensado en la producción de nitrato de amonio en una empresa petroquímica productora de fertilizantes en Cartagena(2018-10-03) Argüello Quintero, María Fernanda; Suárez Reyes, Ana Teresa; Matute Thowinson, AdalbertoIn the next project will be presented the alternative that will allow to recover the percentage of water that is in the process condensate, result of the operations in the ammonium nitrate plant of a fertilizer production company located in Cartagena, which contains traces of ammonia above the regulation in Decree 1594 of 1984 with respect to the dumping of industrial wastewater. To give solution to the above, we propose the design of a distillation column that will allow to recover 99% of the water contained in the tower feeding, separating the traces of ammonia contained in the condensate. This scenario can be analyzed by using the Aspen Process simulation Tool "HYSYS", contemplating the operational alternatives for the treatment of the currents involved and also obtain a model that allows to comply with the Specifications needed to reuse current products, at the end of the simulation was expected to obtain a distillation flow whose composition is 99% ammonia, thus releasing the current of funds from the contamination that this substance represents and Recovering the water from this operation, this was achieved by optimizing the initial design by means of a suggested energy integration for the purposes of this project
- PublicaciónAcceso abiertoElaboración del duelo tras el divorcio. Una perspectiva psicoanalítica(Universidad de San Buenaventura, 2017) Sanz Barragán, Withny Talía; Mercado Lenis, Diego FernandoThe following is a qualitative research of constructive and interpretative nature of the process of elaboration of the duel of four divorced persons, approached from the field of reality of a scientific investigation and from the psychoanalytic perspective, of authors like, Sigmund Freud, Dorian Leader, Otto Kernberg and Igor Caruso, who allowed to understand the mourning after the loss of an object of love as an event that has implications in the psychic apparatus of the one who suffers it, since in losing its object of love, it is as if it lost a part of Itself generating particular ways of carrying out their loss, nonetheless, other cultural variables were taken into account, since rites, celebrations reveal many things about a family and their particular ways of relating and coping with the various situations Of life, specifically with the couple. Also, a series of symbolic resources appear that facilitate the assimilation of the loss. According to the above, a series of questions were generated that were used as a guide for research. What does the culture provide for the divorced? What role does divorce play as a legal act? What are the attitudes of those who surround the divorced? And what is the role of these symbolic elements in the psychic elaboration - in the psychoanalytic sense - of such a loss?
