Abstract
A rapid thermal processing system includes an inorganic heat carrier particles reheater coupled to an inorganic particle cooler. For example. inorganic heat carrier particles may be cooled in a shell and tube inorganic particle cooler by indirect heat exchange with a cooling medium. The cooled inorganic heat carrier particles may then be supplied to a reactor to transfer heat to carbonaceous material.
Claims20
A method for controlling heat for rapid thermal processing of carbonaceous material, comprising:
- i) combusting char with an oxygen-containing gas in the presence of inorganic particles to form heated inorganic particles;
- ii) contacting a first portion of the heated inorganic particles with an exterior of at least one of a plurality of cooling tubes, wherein the at least one of the plurality of cooling tubes comprises:
- a) an outer tube comprising the exterior;
- b) an inner tube concentrically disposed within the outer tube;
- and
- c) an outer channel defined by the outer surface of the inner tube and the interior of said outer tube;
- iii) supplying cooling medium to the outer channel;
- iv) heating the cooling medium in the outer channel to partially cool the first portion of heated inorganic particles;
- and
- v) removing the heated cooling medium from an end of the inner tube.
A method for controlling heat for rapid thermal processing of carbonaceous material, comprising:
- i) combusting char with an oxygen-containing gas in the presence of inorganic particles in a reheater to form heated inorganic particles;
- ii) advancing a generally downward flow of a first portion of the heated inorganic particles through a shell portion of an inorganic particle cooler into contact with an exterior of at least one of a plurality of generally horizontal cooling tubes disposed therein, wherein the at least one of the plurality of cooling tubes comprises:
- a) an outer tube comprising the exterior;
- b) an inner tube concentrically disposed within the outer tube;
- and
- c) an outer channel defined by the outer surface of the inner tube and the interior of said outer tube;
- iii) supplying cooling medium to the outer channel;
- iv) heating the cooling medium in the outer channel to partially cool the first portion of heated inorganic particles;
- v) removing the heated cooling medium from an end of the inner tube;
- vi) directing the partially-cooled first portion of heated inorganic particles with an air stream through a lift riser to a sand-air distributor positioned in the reheater above a gas distributor;
- and
- vii) distributing the air stream and the partially-cooled first portion of heated inorganic particles in the reheater, whereby a second portion of the heated inorganic particles present in the reheater is partially cooled.
