Ítem Booklet Use of Antioquian propolis. Quality criteria and extraction protocols(Universidad EAFIT, 2021) Marín Palacio, Luz Deisy; Builes Toro, Santiago; Barrientos Lezcano, Juan Camilo; Universidad EAFITThis booklet is aimed at beekeepers in the Antioquia region, and aims to improve the processes of collecting and extracting propolis in beekeeping communities.Ítem Cement in-line calciner kiln modeling for heat optimization using a design of computer experiments(Universidad EAFIT, 2020) Ortiz Muñoz, Alejandro; Builes Toro, Santiago; Acosta Maya, Diego Andrés; Acosta Maya, Diego AndrésA model of a dry process cement kiln was implemented in Aspen Plus V9 and validated with a 2000 metric ton per day in-line calciner cement kiln data. A simpli ed model of the process was obtained using a 20-run Plackett-Burman design of experiments on Aspen Plus simulations with 19 input variables related to false air (in-leakage air), oxygen concentration, calciner temperature, cyclones e ciency and clinker's cooler bed height. Linear metamodels for the speci c heat consumption (SHC) and other response variables were obtained. The metamodel indicated that (i) false air in cyclones 4 and 5, (ii) calciner's control temperature, (iii) oxygen concentration at the calciner exit and (iv) cooler's clinker bed height were the most signi cant input variables a ecting SHC. The SHC obtained from simulation based on the optimized values from the metamodel resulted in a reduction of ca. 29 kcal/kg of clinker. A sensitivity analysis indicated that the two most impacting variables were the oxygen concentration at the calciner's exit and the cooler's clinker bed depth. The SHC metamodel is a powerful tool for capturing the complexity of the process simulations on a simple and easy to use model.Ítem Fast Correction of Errors in the DFT-Calculated Energies of Gaseous Nitrogen-Containing Species(Universidad EAFIT, 2021) Urrego-Ortiz, Ricardo; Calle-Vallejo, Federico; Builes Toro, Santiago; Calle-Vallejo, Federico; Builes Toro, SantiagoÍtem Introduction to methodologies for extracting bioactive compounds from propolis(Universidad EAFIT, 2021) Marín Palacio, Luz Deisy; Builes Toro, Santiago; Barrientos Lezcano, Juan Camilo; Universidad EAFITThis document describes the main methods used for the extraction of active compounds from propolis.Ítem Quality criteria for propolis analysis(Universidad EAFIT, 2021) Marín Palacio, Luz Deisy; Builes Toro, Santiago; Barrientos Lezcano, Juan Camilo; Universidad EAFITThis document describes the main methodologies and criteria used to measure the quality of propolis.
