Abstract
The characteristics of the hydraulic permeation of flue gas desulfurization (FGD) effluents in a polyamide membrane were studied under various operating pressures and temperatures. It was found that the water flux and solute rejection increased with an increase in the operating pressure. According to these results, a modified solution–diffusion model developed by Yang & Chu was used to describe the case of the FGD effluent transport through a polyamide membrane under various operating pressures and temperatures, which were discussed and evaluated as the respective transport parameters. It was found that the diffusivity for water increased with increasing temperature and the activation energy of diffusivity for water was 11.4 kJ/mole. Moreover, the permeability for solute increased with increasing temperature and the activation energy of permeability of salt was 22.1 kJ/mole.
