EFFECT OF MEMBRANE SEPARATION PROCESS CONDITIONS ON THE RECOVERY OF SYNGAS COMPONENTS
Original language description
The presented study focuses on inspecting the dependency between process conditions, especially permeate and retentate pressure, and component recovery of H2, CO, and CO2 during membrane separation of model syngas. Experiments with both pure components and a model mixture were performed using a laboratory membrane unit Ralex GSU-LAB-200 with a polyimide hollow fibre module with 3000 hollow fibres. Permeability values were established at 1380 Barrer for H2, 23 Barrer for CO, and 343 Barrer for CO2. The measured selectivities differ from the ideal ones: the ideal H2/CO2 selectivity is 3.21, while the experimental values range from over 4 to as low as 1.2 (this implies that interaction between components takes place). Then, model syngas containing 16% H2, 34% CO, and 50% CO2 was tested. The recovery of each component decreases with increasing permeate pressure. At pressure difference 2 bar, the recovery for H2 for permeate pressure 1.2 bar is around 68 %, for 2.5 bar the values drop to 51% and for 4 bar the values reach 40 % only. A similar trend was observed for CO2, with recovery values of 59 %, 47 % and 37 % for permeate pressures of 1.2 bar, 2.5 bar and 4 bar, respectively.
