Esta situación se agravará por la inclusión de nuevas unidades de proceso que incrementarán dichas emisiones. En este sentido, es objetivo de esta investigación proponer un despojador cáustico, para el tratamiento de los gases residuales en la unidad que permita el cumplimiento de los parámetros de proceso y reduzca las emisiones gaseosas. Se realiza un estudio bibliográfico sobre los procesos de tratamientos de gases residuales y las diferentes tecnologías que se utilizan. A partir de este estudio se analizan los principales aspectos constructivos y de operación que deben tener los despojadores húmedos. Se presentan los parámetros de diseño y operación del despojador, así como, las características constructivas del mismo, sentando las bases para la evaluación. Luego se presenta la metodología de evaluación de la torre empacada obteniéndose el modelo de simulación utilizando el Simulador ProMax® 2.0 y que permite definir el rango de operación del mismo, mediante el análisis de sensibilidad. Finalmente se evalúa económicamente la propuesta de mejora tecnológica con los indicadores dinámicos de rentabilidad VAN, TIR y PRD. Como resultado se espera reducir las emisiones atmosféricas inferiores a 150 mg/Nm3 como SO2, disminuir el consumo energético en la unidad de azufre y la exposición de la población en general a las emanaciones gaseosas.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ ABSTRACT The selected technology for the sulfur recovery in the Cienfuegos oil`refinery does not achieve the quality parameters required for said process as it causes gaseous SO2 emissions outside the established regulatory framework. This situation will be aggravated by the inclusion of new process units that will increase said emissions. In this sense, the objective of this research is to propose a caustic stripper for the treatment of waste gases in the unit that allows compliance with the process parameters and reduces gaseous emissions. A bibliographic study is carried out on the waste gas treatment processes and the different technologies that are used. Based on this study, the main construction and operational aspects that wet strippers must have are analyzed. The design and operation parameters of the stripper are presented, as well as its constructive characteristics, laying the foundations for the evaluation. Then the evaluation methodology of the packed tower is presented, obtaining the simulation model using the ProMax® 2.0 Simulator, which allows defining its operating range, through sensitivity analysis. Finally, the technological improvement proposal is economically evaluated with the dynamic profitability indicators VAN, TIR and PRD. As a result, it is expected to reduce atmospheric emissions below 150 mg / Nm3 as SO2, reduce energy consumption in the sulfur unit and the exposure of the general population to gaseous emanations.]]></p></abstract>
