This process involves a reversible\u0000reaction between sorbent Calcium Oxide and Carbon Dioxide. Because sorbent loses its\u0000activity after multiple cycles, hydration step was proposed, which is another reversible\u0000reaction where deactivated sorbent is treated with steam to form Ca(OH)2, which undergoes\u0000the backward reaction to give back the regenerated sorbent. Blamey et al. (2016)\u0000developed a shrinking core model based on which, studies were carried out on a small\u0000experimental reactor. This paper aims at developing a hybrid model by combining first\u0000principles model and an ANN model for improved prediction of the conversion in hydration\u0000of calcium looping process and to scale it up for optimal operations. The hybrid\u0000model is tested for various combinations of training variables and data sets with respect to\u0000temperature and cycle number and it is found that the hybrid model indeed gives better\u0000results.

The International Conference on Structural Nonlinear Dynamics and Diagnosis intends to be a meeting place for scientists from different branches of applied mechanics and mathematics working in nonlinear dynamics, structural systems, diagnosis and control can meet to discuss the latest achievements and to exchange ideas in theoretical, numerical and experimental techniques for solving problems in nonlinear dynamics, diagnosis and control. Focuses are directed toward diverse topics, ranging from dynamical systems theory to different engineering applications. This first CSNDD 2012 aims at covering a large field of nonlinear dynamics, including structural health monitoring, diagnosis and damage detection, fast slow dynamics, multi-scale dynamics, advances on nonlinear PDEs and their dynamics, experimental methods, active vibration control and smart structures, identification of nonlinear systems, vibro-impact dynamic, and nonlinear dynamics in MEMS / NEMS and nanotechnology. The Moroccan Association of Vibration and Acoustic would like to make this meeting a tradition and sets a goal of organizing the event every two or three years in Morocco and in the nearby countries. It is a great privilege for the nonlinear dynamic Moroccan community, in general, and the Casablanca research group, in particular, to host the CSNDD 2012 conference in Marrakech, as the first international conference in nonlinear dynamics organized in Morocco. The first CSNDD 2012 has amply accomplished this goal. The event has attracted a representative international scientific community in nonlinear dynamics, diagnosis and control. More than 200 papers from 28 countries were submitted, most of them being invited, and nearly 160 were accepted for presentation and 67 were accepted for publication in MATEC Web of Conferences. Thirteen Mini-symposia including fifteen oral and two poster sessions were organized by leading experts in the field, who contributed to attract top-quality scientists. All submissions were reviewed. I would like to thank the Keynote lecturers, the invited speakers, all MS organizers, reviewers and other volunteers for their help in maintaining high standards of the Conference Technical Program. At the same time, I would like to thank all participants to the Conference, as well as PhD students, colleagues and friends who meaningfully helped with the organization.","PeriodicalId":38021,"journal":{"name":"Recent Innovations in Chemical Engineering","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43886167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
