In order to facilitate the handling of cardiopulmonary bypass (CPB) and simplify the circuit, we have developed a new membrane oxyganator with a hemofiltration function. The hollow fiber units for gas exchange and hemofiltration were combined in concentric circles in a cylindrical housing. The total priming volume was 190 ml. Because we used a silicon-coated hollow fiber membrane for gas exchan...

In this study, hydrogen was recovered and purified by using a membrane contactor unit from CO2-rich gas without the use of any basic chemicals such as amines. The operational parameters were adjusted to achieve high CO2 removal H2 recovery. effects flow rate, pressure, composition (CO2/H2 ratio), pressure difference between liquid gas, gas/liquid ratio on recovery investigated. Depending contac...
