Desarrollo de una tecnología innovadora para la mitigación del cambio climático: absorción no dispersiva con líquidos iónicos. Development of an innovative technology for climate change mitigation: non-dispersive absorption with ionic liquids

Abstract

La Captura y Almacenamiento de dióxido de Carbono (CAC), es una tecnología orientada a mitigar el impacto de los gases de efecto invernadero producidos en la quema de combustibles fósiles en procesos industriales y de generación de energía, donde la captura de dióxido de carbono (CO2) supone el cuello de botella del proceso, y por tanto donde deben centrarse los esfuerzos. En este contexto, el objetivo de este trabajo es la intensificación del proceso de absorción de CO2 convencional en dos etapas: i) Sustitución del equipamiento convencional (e.g. torres de absorción) por sistemas de membranas para una absorción no dispersiva que elimine el arrastre de gotas y, ii) Sustitución del absorbente de referencia (monoetanolamina, MEA) por líquidos iónicos, con presión de vapor despreciable, que permite eliminar las pérdidas de disolvente por volatilización. En la presente Tesis Doctoral se desarrolla un proceso con cero emisiones de disolvente mediante la integración de equipos de membranas y líquidos iónicos, como estrategia para la intensificación del proceso de captura de CO2 de post-combustión.

Carbon dioxide Capture and Storage (CCS), is a technology aimed at mitigating greenhouse gas impacts from fossil fuels combustion in industrial and energy-related processes where, carbon dioxide (CO2) capture is the bottleneck step where the efforts have to be applied. In this context, the aim of this work is to intensify the absorption process by two steps: i) Substitution of conventional equipment (e.g. scrubbers) for non-dispersive absoprtion membrane systems to avoid drops dragging and, ii) Substitution of the reference absorption solvent (monoethanolamine, MEA) for ionic liquids, with negligible vapour pressure, to avoid solvent losses due to volatilization of the solvent into gas stream. Thereby, in this PhD Thesis a zero solvent emission process trough the integration of membrane systems and ionic liquids is developed as a process intensification strategy for the recovery of CO2 from post-combustion streams.
