| contents | Estimation of energy to be supplied from an external source to heat or to compress alcohols (C3-C12) in gas phase Moilton R. Franco Junior Geología Energy Heating Alcohols Compression Thermodynamic In-process energy expenditure is cutting-edge research in the general field of energy application.In this paper, the amount of energy for heating or compressing a system in gas phase was estimated by using the thermodynamic equations. Firstly, thesystems were chosen and among the alcohols, we used them from C3 to C12 to discussthe effect of number of carbons atoms in the chain. Secondly, the Peng-Robinson equation represented the pVT system behavior. Also, influences of the level in temperature and pressure was analyzed. The results show that the energy expended for isobaric heating was very similar in value regardig the pressure range (1-20 atm).The number of carbons in the chain had significant influence on the heating result of alcohols, as well as in the solution of integral of pdV. For isothermic compression, when the process ocurred at low pressures (1 to 5 atm),the amount of spent energy was pratically constant for all alcohols studied. Furthermore, for the same pressure range, as the temperature increases, the energy required to compress increases.Because there is no influence of the pdV term, internal energy change could be considered as the same of spent energy in the process. The main conclusions drawn from this work will be helpful for future development of of efficient equipment such as combustion engines. 2024 artículo científico 0329-8922 https://www.redalyc.org/articulo.oa?id=382679692003 https://www.redalyc.org/journal/3826/382679692003/ https://www.redalyc.org/journal/3826/382679692003/html/ https://www.redalyc.org/journal/3826/382679692003/382679692003.epub https://www.redalyc.org/journal/3826/382679692003/movil 10.36995/j.recyt.2024.41.003 en http://www.redalyc.org/revista.oa?id=3826 Revista de Ciencia y Tecnología application/pdf Universidad Nacional de Misiones Revista de Ciencia y Tecnología (Argentina) Num.1 Vol.41 |
