文摘
- •
A non-isothermal numerical model was developed for dual reflux pressure swing adsorption cycles.
- •
Bed pressure, flow and temperature profiles from N2 + CH4 experiments were well matched.
- •
Predicted CH4 mole fractions had r.m.s. deviations of 0.003 and 0.024 for the light and heavy products.
- •
Simulations provide insight into the optimisation of the feed step time and mass transfer effects.
