Abstract
A membrane module includes a housing. The housing includes a housing, comprising: a first plurality of porous hollow fiber membranes, and a second plurality of porous hollow fiber membranes different from the first plurality of porous hollow fiber membranes. The first plurality of porous hollow fiber membranes has a first length, and the second plurality of porous hollow fiber membranes has a second length that is at least 1.1 times greater than the first length. The membrane module can be used in separation methods, such as membrane distillation methods.
Claims20
A system, comprising:
- a first source configured to provide a first gas, the first gas comprising oxygen gas;
- a second source configured to provide a second gas, the second gas comprising sulfur dioxide;
- a third source configured to provide a liquid comprising water;
- and
- a membrane module, comprising:
- a housing, comprising:
- a plurality of porous hollow fiber membranes,
- wherein the system is configured so that, within the module, the sulfur dioxide reacts with the water to form products that undergo oxidation and neutralization to remove the sulfur dioxide from the second gas;
- and
- wherein the plurality of porous hollow fiber membranes comprises a first plurality of porous hollow fiber membranes and a second plurality of porous hollow fiber membranes different from the first plurality of porous hollow fiber membranes.
A system, comprising:
- a first source configured to provide a first gas, the first gas comprising oxygen gas;
- a second source configured to provide a second gas, the second gas comprising sulfur dioxide;
- a third source configured to provide a liquid comprising water;
- and
- a membrane module, comprising:
- a housing, comprising:
- a plurality of porous hollow fiber membranes,
- wherein the system is configured so that:
- the first gas has a flow path through the module;
- the second gas has a flow path through the module that is different from the flow path of the first gas through module;
- the liquid has a flow path through the module that is different from both the flow path of the first gas through module and the flow path of the second gas through the module;
- and
- the plurality of porous hollow fiber membranes comprises a first plurality of porous hollow fiber membranes and a second plurality of porous hollow fiber membranes different from the first plurality of porous hollow fiber membranes.
A method, comprising:
- simultaneously introducing a first gas comprising sulfur dioxide into a first plurality of hollow fiber membranes of a membrane module, a second gas comprising oxygen gas into a second plurality of hollow fiber membranes of the membrane module, and water into an inner space of the membrane module so that, within module, sulfur dioxide is removed from the first gas,
- wherein:
- each of the first gas, the second gas and the water has a different flow path within the membrane module;
- and
- the first plurality of hollow fiber membranes is different from the second plurality of hollow fiber membranes.
