Abstract
Systems and methods of separating components of a multi-component gas mixture are described herein. The systems include one or more packed bed columns packed with a biosorbent material. Upon passing the multi-component gas mixture through the packed bed column, substantially all of a polar component of the multi-component gas mixture is adsorbed by the biosorbent material and a non-polar component of the multi-component gas mixture is not substantially adsorbed by the biosorbent material.
Claims60
A system for separating components of a multi-component gas mixture, the system comprising a packed bed column packed with a biosorbent material,
- wherein, upon passing the multi-component gas mixture through the packed bed column, substantially all of a polar component of the multi-component gas mixture is adsorbed by the biosorbent material and a non-polar component of the multi-component gas mixture is not substantially adsorbed by the biosorbent material.
A method of separating components of a multi-component gas mixture, the method comprising:
- passing a feed stream comprising the multi-component gas mixture through a packed bed column comprising a biosorbent material for the biosorbent material to adsorb substantially all of a polar component of the multi-component gas mixture and to not substantially adsorb a non-polar component of the multi-component gas mixture.
A system for separating components of a multi-component gas mixture, the system comprising:
- a feed stream comprising the multi-component gas mixture;
- a first packed bed column packed with a biosorbent material and configured to receive the multi-component gas mixture from the feed stream;
- a second packed bed column packed with the biosorbent material and configured to receive the multi-component gas mixture from the feed stream;
- and
- a product stream configured to receive a dried gas from each of the first and the second packed bed columns, the dried gas comprising substantially all of a non-polar component of the multi-component gas mixture;
- wherein upon passing the multi-component gas mixture through the first packed bed column substantially all of a polar component of the multi-component gas mixture is adsorbed by the biosorbent material and the non-polar component of the multi-component gas mixture is not substantially adsorbed by the biosorbent material.
A method of separating components of a multi-component gas mixture, the method comprising:
- operating a first packed bed column in an adsorption process by passing a feed stream comprising the multi-component gas mixture through the first packed bed column comprising a biosorbent material for the biosorbent material to adsorb substantially all of a polar component of the multi-component gas mixture and to not substantially adsorb a non-polar component of the multi-component gas mixture;
- and
- operating the first packed bed column in a regeneration process by drawing substantially all of the polar component adsorbed by the biosorbent material off of the biosorbent material.
A system for controlling the separation of components of a multi-component gas mixture in a pressure swing or a temperature swing adsorption process, the system comprising:
- a computing unit configured to:
- operate a first packed bed column in an adsorption process by passing a feed stream comprising the multi-component gas mixture through the first packed bed column comprising a biosorbent material for the biosorbent material to adsorb substantially all of a polar component of the multi-component gas mixture and to not substantially adsorb a non-polar component of the multi-component gas mixture;
- and
- operate the first packed bed column in a regeneration process by drawing substantially all of the polar component adsorbed by the biosorbent material off of the biosorbent material.
A system for controlling the separation of components of a multi-component gas mixture in a pressure swing or a temperature swing adsorption process, the system comprising:
- a computing unit configured to:
- pressurize a first packed bed column by directing a feed stream comprising the multi-component gas mixture into the first packed bed column, the first packed bed column comprising a biosorbent material for the biosorbent material to adsorb substantially all of a polar component of the multi-component gas mixture and to not substantially adsorb a non-polar component of the multi-component gas mixture;
- direct the non-polar component from the first packed bed column to a product stream;
- and
- collect the polar component off of the biosorbent material and into a recycle stream.
