Some of the most promising membranes for O2/N2 gas separation (air separation) mentioned in literature so far are selected, in terms of meeting a O2-gas-production breakeven cost that is lower than that of competing air separation unit (ASU) technologies, based on latest reported technoeconomic studies. An overview regarding most important applications of O2 and N2 gases is first given, in respect with the demanded purity limits for each case, since the purity parameter is crucial in defining the minimum breakeven cost.

“…Since these CaSO4 crystals are considerably larger than the CaSO3 formations, the sulfate settling and dewatering rates are greater than twice the sulfite rates. 3 Such improved settling and dewatering significantly reduces the equipment size and saves from 25-50% of the present worth cost for treating the FGD sludge. 4 Such economics justify the expense of introducing air within the FGD system to augment the natural oxygen present in flue gas excess air and to increase the SO4/SO3 ratio to achieve higher oxidation.…”
