Após a realização deste trabalho foi possível obter os seguintes entendimentos:
Os coeficientes de transferência de massa podem ser determinados pelo balanço de massa e a Equação diferencial da transferência de massa:
- Fase líquida: na forma direta;
- Fase gasosa: aplicando a média logarítmica em CG para auxiliar numa estimativa de
condições de operação de uma coluna de absorção com líquido estagnado, o que antes era geralmente aplicado em reator de mistura.
A estimativa do coeficiente global volumétrico de transferência de massa KGa na
absorção física, sendo considerado constante, permite predizer o CL do H2S na fase líquida
durante a absorção com reação química permitindo estimar os parâmetros cinéticos do processo;
A análise da cinética da absorção química pode ser determinada através da modelagem dos dados experimentais utilizando a absorção física como base para a predição da
concentração do H2S na fase líquida e, por conseguinte as concentrações dos reagentes
durante todo o processo.
Os modelos desenvolvidos neste trabalho permitiu avaliar a absorção em uma coluna com líquido estagnado, a partir de uma relação de operação entre a concentração de entrada e a de saída do gás, propiciando a este tipo de processo um tratamento de dados mais simplificado e em condições operacionais relacionadas com um sistema em contínuo.
