Energy recovery from effluents of supercritical water oxidation reactors

Producción CientíficaSupercritical water oxidation (SCWO) reactors can process waste effluents achieving high conversions, but the required extreme pressure and temperature operational conditions entail high-energy operational expenditure. SCWO has the potential to be considered a clean energy generation process, as the process effluent is a high temperature, high pressure stream with a high enthalpy content that can be converted to heat and shaft work. This ensures the self-sustained reaction and can generate excess shaft power to drive both the high-pressure pump and the air compressor. On the contrary, an efficient heat and power recovery from SCWO reactors outlet streams using conventional procedures presents several problems. First, Rankine cycles impose indirect heat transfer to the working fluid and are unable to recover the pressure energy and second, direct expansion of the effluents entails costly development of specific, efficient expansion equipment. In this work, we investigate the options for energy recovery of SCWO reactors coupled with commercial gas turbines (GT). SCWO outlet streams are mainly composed of water, nitrogen and carbon dioxide. These operating values nearly resemble the well-known and already-implemented GT steam injection procedures. The temperature of the flue gases (approx. 500 °C) and the direct shaft work usage offers adequate energy integration possibilities for both feed preheating and compression. The wide range of commercially available GT sizes enables process scaling.Ministerio de Economía, Industria y Competitividad - FEDER (Proyect CTQ2013-44143-R

Analysis of the energy flow in a municipal wastewater treatment plant based on a supercritical water oxidation reactor coupled to a gas turbine

Producción CientíficaBiological municipal wastewater treatments lead to high sludge generation and long retention times, and the possibilities for recovery of the energy content of the input waste stream are very limited due to the low operating temperature. As an alternative, we propose a sequence of exclusively physicochemical, non-biological stages that avoid sludge production, while producing high-grade energy outflows favoring recovery, all in shorter times. Ultrafiltration and evaporation units provide a front-end concentration block, while a supercritical water oxidation reactor serves as the main treatment unit. A new approach for energy recovery from the effluent of the reactor is proposed, based on its injection in a gas turbine, which presents advantages over simpler direct utilization methods from operational and efficiency points of view. A process layout and a numerical simulation to assess this proposal have been developed. Results show that the model process, characterized with proven operating parameters, found a range of feasible solutions to the treatment problem with similar energy costs, at a fast speed, without sludge production, while co-generating the municipality’s average electricity consumption.Ministerio de Ciencia e Innovación - (Grant RTI2018- 097456-B-100

Supercritical water oxidation for energy production by hydrothermal flame as internal heat source. Experimental results and energetic study

Producción CientíficaThe cooled wall reactor has been modified by adding an additional upper outlet of products at 500–700 °C to improve energy recovery and make possible energy generation with the supercritical water oxidation of different waste. Experimental and modeling results of the performance of this new reactor configuration are presented as well as a theoretical analysis of the energy recovery of the reactor compared to other supercritical water oxidation reactors. Different flow distributions were tested to find the best elimination conditions. Total organic carbon removal over 99.99% was obtained at room injection temperatures, when the fraction of products leaving the reactor in the upper effluent is lower than 70% of feed flow. The performance of the reactor was tested with the oxidation of a recalcitrant compound such as ammonia. Removals higher than 99% of were achieved at temperatures near 700 °C. The behavior of the reactor working with feeds with up to 2.5% wt Na2SO4 could be injected in the reactor without plugging problems. Upper effluent always presented a concentration of salt lower than 30 ppm. Theoretical energetic analysis shows that the performance of this reactor is superior to other designs obtaining a maximum power efficiency of 27% (0.339 kW/kg-feed).Ministerio de Economía, Industria y Competitividad - FEDER (Proyect CTQ2013-44143-R

Vídeos para apoyo al aprendizaje en las áreas de Ingeniería Química y Tecnologías del Medio Ambiente

Elaboración de screencasts/podcasts (vídeos que resultan de la grabación de imagen de pantalla y el sonido de las explicaciones del docente) para substituir a una parte substancial de las explicaciones teóricas que tradicionalmente se llevan a cabo en el aula. Se han elaborado vídeos de apoyo para la docencia teórica y/o práctica de dos asignaturas del Máster de Ingeniería Química, y bloques de clases teóricas de asignaturas de primer y cuarto curso del Grado Ingeniería Química y se han empleado en la docencia. Se han elaborado también numerosos vídeos con temática relacionada con la docencia del Departamento por los participantes no encuadrados en el desarrollo de medios para las asignaturas citadas.Departamento de Ingeniería Química y Tecnología del Medio AmbienteVídeos elaborados en el PROYECTO DE INNOVACIÓN DOCENTE 2020/2021 Ref:089 "Vídeos para apoyo al aprendizaje en las áreas de Ingeniería Química y Tecnologías del Medio Ambiente
