Modeling of the performance of BSCF capillary membranes in four-end and three-end integration mode

摘要: Abstract Owing to their high surface-to-volume ratio, there has been an increasing research interest in mixed ionic–electronic conducting (MIEC) capillary membranes for large-scale temperature oxygen separation applications. They offer energy-efficient solution combustion processes oxy-fuel and pre-combustion CO 2 capture technologies used fossil fuel power plants. In order assess the effectiveness of these plant applications, impact geometry Ba 0.5 Sr Co 0.8 Fe 0.2 O 3− δ (BSCF) capillaries on performance three-end four-end integration modes investigated thoroughly discussed. The model's parameters were derived from mode lab-scale experiments using gas-tight, macrovoid free sulfur-free BSCF that prepared by a phase-inversion spinning technique. results this modeling study revealed higher average fluxes smaller total membrane areas can be obtained than mode. This is due pO gradient across wall.
