| description |
The chlorine production process via electrolysis is important in the chemical industry
due to the wide application of this product in several areas. After the production of chlorine via
electrolysis, the chlorine undergoes some treatment steps in order to be commercialized and
used in other process routes. Within them, the liquefaction of chlorine is necessary to reduce
the temperature of the chlorine to the point of liquefying almost entirely. In this operation, shell
and tube type heat exchangers are used. One of the factors that impact the efficiency of these
equipment is the type of refrigerant to be used. The choice of fluid is gaining importance,
because in addition to its energy capacity, environmental concern is present due to the entire
current context. Therefore, the present work aimed to analyze the efficiency of three refrigerants
in the process, R-134A, R-12 and R-1234YF, considering their liquefaction capacity and the
environmental impact compared through indices the Ozone Depletion Potential (ODP) and
Global Warming Potential (GWP). The operating conditions of the heat exchangers were used
as a basis for simulation in the Aspen Hysys software. The results obtained in the simulation
were used to perform the analysis of better efficiency in the process together with the
comparison of the environmental indices. From the results it was found that the fluid R-134A
is more efficient when it is related to the liquefaction capacity, however, the R-1234YF has the
lowest environmental impact. |

O processo de produção do cloro via eletrólise é importante na indústria química devido a vasta aplicação desse produto em diversas áreas. Após a produção do cloro via eletrólise, o cloro passa por algumas etapas de tratamento para poder ser comercializado e utilizado em outras rotas de processo. Dentro delas, a liquefação do cloro se faz necessária para reduzir a temperatura do cloro ao ponto de liquefazer por quase toda sua totalidade. Nessa operação utiliza-se trocadores de calor do tipo casco e tubo. Um dos fatores que impactam na eficiência desses equipamentos é o tipo de fluido refrigerante a ser utilizado. A escolha do fluido cada vez vem ganhando importância, pois além da sua capacidade energética, a preocupação ambiental se faz presente devido todo o contexto atual. Diante disso, o presente trabalho teve como objetivo analisar a eficiência de três fluidos refrigerantes no processo, o R-134A, R-12 e R 1234YF, levando em conta sua capacidade de liquefação e o impacto ambiental comparado através dos índices Ozone Depletion Potential (ODP) e Global Warming Potential (GWP). As condições operacionais dos trocadores de calor foram utilizadas como base para simulação no software Aspen Hysys. Os resultados obtidos na simulação foram utilizados para realizar as análises de melhor eficiência no processo juntamente com a comparação dos índices ambientais. A partir dos resultados verificou-se que o fluido R-134A é mais eficiente quando está relacionado a capacidade de liquefação, porém, o R-1234YF tem o menor impacto ambiental. 2022-07-27T13:14:01Z 2022-07-27T13:14:01Z 2022-07-18 bachelorThesis OLIVEIRA, Samilly Cristine Alves de Oliveira.
