  • sweep uniformity effect on gas dehydration module performance;
  • membrane gas separation for air dehydration (AD);
  • hollow fibre module - in three modes, co-current, cross or counter-current flow;
  • Gaussian distribution of sweep flow and mass balances for each fibre in module;
  • Hagen-Poiseuille equation;
  • explicit sweep distribution simulations;
  • module performance with ideal sweep distribution;
  • sweep and ID variation effects;
  • sweep flow variability in individual fibres - little effect on module performance;
  • sweep uniformity on performance of hollow fibre gas dehydration modules
