Abstract
A biomethanol production system and method is provided. The system comprises (a) a feed stream comprising methane, water, and carbon dioxide; (b) a reformer reactor capable of reacting the feed stream to form a syngas mixture comprising hydrogen, carbon monoxide, and carbon dioxide; (c) a methanol reactor capable of reacting the syngas mixture to form biomethanol product; (d) a wash column comprising the syngas mixture and the biomethanol product, wherein the biomethanol product is capable of absorbing carbon dioxide from the syngas mixture; and (e) a flash column comprising a vent capable of venting the absorbed carbon dioxide. A method for removing carbon dioxide from a biomethanol production system is also provided.
Claims18
A biomethanol production system comprising:
- a feed stream comprising methane, water, and carbon dioxide;
- a prefilter including an activated carbon filter designed to remove at least one contaminant from the feed stream;
- a reformer reactor capable of reacting the feed stream to form a syngas mixture comprising hydrogen, carbon monoxide, and carbon dioxide;
- a methanol reactor capable of reacting the syngas mixture to form biomethanol product;
- a wash column comprising the syngas mixture and the biomethanol product, wherein the biomethanol product is capable of absorbing carbon dioxide from the syngas mixture;
- a flash column comprising a vent capable of venting the absorbed carbon dioxide;
- a methanol recycle stream comprising biomethanol discharged from the flash column, wherein the methanol recycle stream places the flash column in fluid communication with the wash column;
- and
- a liquid transport device configured to transport biomethanol in the methanol recycle stream from the flash column to the wash column.
A biomethanol production system comprising:
- a feed stream;
- a prefilter including an activated carbon filter designed to remove a contaminant from the feed stream;
- a reformer reactor configured to react the feed stream to create a syngas mixture;
- a first methanol reactor configured to react the syngas mixture to form a first biomethanol product;
- a wash column configured to absorb carbon dioxide from the syngas mixture, the wash column including a wash column discharge line;
- a second methanol reactor configured to react the syngas mixture to form a second biomethanol product, wherein the wash column discharge line puts the wash column in fluid communication with the second methanol reactor;
- a device configured to release absorbed carbon dioxide from the first and second biomethanol product and vent the absorbed carbon dioxide from the biomethanol production system;
- and
- a biomethanol recycle stream that puts the device in fluid communication with the wash column.
A biomethanol production system comprising:
- a feed stream comprising biogas;
- a prefilter comprising an activated carbon filter designed to remove at least one contaminant from the feed stream;
- a reformer reactor configured to react the feed stream to generate a syngas mixture;
- a first methanol reactor including a first input line and a first discharge line, the first methanol reactor designed to react the syngas mixture to form a first biomethanol stream, wherein the first biomethanol stream is provided to the first discharge line;
- a second methanol reactor including a second input line and a second discharge line, wherein the second methanol reactor is positioned downstream of the first methanol reactor and is designed generate a second biomethanol stream that is provided to the second discharge line;
- a wash column in fluid communication with the first discharge line of the first methanol reactor and the second input line of the second methanol reactor, wherein the wash column provides a wash column discharge stream to the second methanol reactor;
- a flash column in fluid communication with the wash column and the second methanol reactor, the flash column designed to vent absorbed carbon dioxide to generate a biomethanol product stream;
- a methanol recycle line including a methanol recycle stream, wherein the methanol recycle stream comprises a portion of the biomethanol product stream discharged from the flash column, wherein the methanol recycle stream places the flash column in fluid communication with the wash column;
- and
- a liquid transport device coupled to the methanol recycle line between the flash column and the wash column.
