Conclusions
➢ The separation of ternary gas mixtures was investigated in three hollow-
fibre membrane modules. In the gas stream containing 70 vol.% of CO2 the
O2 concentration was varied between 0 and 5 vol.%
➢ It is found that the presence of oxygen leads to a drop in the concentration
of CO2 in the permeate for each of the commercial modules studied
➢ The experimental studies clearly show that, from the standpoint of the
hybrid adsorptive-membrane process, the Air Products PRISM compares
favourably with the other two commercial modules tested. Thus, it is this
module that was selected as the final section (stage 2) of the hybrid
installation, and the full-scale hybrid experiments further corroborated its
usefulness. The combination of the two separation techniques produced
gas streams with CO2 content exceeding 95 vol.%; the recovery was
virtually complete, as the retentate was recycled to the inlet of the hybrid
installation
