Abstract: A reactor includes a second flow path on a permeation side of a separate membrane. The second flow path includes an inflow port open to a first space between a first seal portion and a flow stop unit, and an outflow port open to a second space between a second seal portion and a flow stop unit. A housing includes a sweep gas supply port for supplying a sweep gas to the first space and a sweep gas exhaust port for discharging the sweep gas from the second space. In a side view of the reactor, a direction in which the sweep gas flows through the second space is opposite to a direction in which the sweep gas flows through the second flow path.

Abstract: A reactor includes a second flow path on a permeation side of a separation membrane. The second flow path includes an inflow port open to a first space between a first seal portion and a flow rate adjustment unit, and an outflow port open to a second space between a second seal portion and a flow rate adjustment unit. A housing includes a sweep gas supply port for supplying a sweep gas to the first space and a sweep gas exhaust port for discharging the sweep gas from the second space. In a side view of the reactor, a direction in which the sweep gas flows from the first space to the second space via the flow rate adjustment unit is the same as a direction in which the sweep gas flows through the second flow path.

Abstract: A method of evaluating a separation membrane module includes a step of supplying a performance degradation gas having a property of reducing permeance of a separation membrane to a primary side of the separation membrane, and a step of, after the previous step, supplying an evaluation fluid to the primary side of the separation membrane to measure a flow rate of the evaluation fluid to a secondary side of the separation membrane.

Abstract: A gas separator includes a separation membrane complex in which a separation membrane with pores having a mean pore diameter less than or equal to 1 nm is formed on a porous support, and a gas supply part that supplies a mixed gas including CO2 and another gas from the side of the separation membrane to the separation membrane complex. Then, CO2 in the mixed gas is caused to permeate through the separation membrane and the support and is separated from the mixed gas in a state in which at least part of a permeation surface of the support, from which a gas having permeated through the separation membrane is exhausted, has a temperature lower by 10° C. or more than the temperature of the mixed gas before being supplied to the separation membrane complex.
