Abstract
This disclosure relates to a processing that includes a first shell and a second shell disposed within the first shell. The second shell includes a first end, a second end, and a wall extending between the first end and the second end. The second shell also defines a cavity and a longitudinal axis extending between the first end and the second end. A cross section of the second shell transverse to the longitudinal axis includes a first arcuate inner wall portion having a first radius of curvature and a second arcuate inner wall portion having a second radius of curvature. The first radius of curvature is larger than the second radius of curvature.
Claims19
A vessel comprising:
- a first shell;
- and
- a second shell disposed within the first shell, the second shell comprising a first end, a second end, and a wall extending between the first end and the second end, the second shell defining a cavity and a longitudinal axis extending between the first end and the second end, a cross section of the second shell transverse to the longitudinal axis including:
- a first arcuate inner wall portion having a first radius of curvature;
- and
- a second arcuate inner wall portion having a second radius of curvature;
- wherein the first radius of curvature is larger than the second radius of curvature;
- and
- wherein the first shell comprises a first outer end, a second outer end, and a first shell wall defining a cylindrical shape that extends between the first outer end and the second outer end.
6 more elements
A system comprising:
- a composition;
- and
- a process vessel configured for processing the composition, the process vessel comprising:
- an inlet opening;
- an outlet opening;
- a first shell;
- and
- a second shell disposed within the first shell, the second shell comprising a first end, a second end, and a wall extending between the first end and the second end, the second shell defining a cavity to hold the composition during processing and a longitudinal axis extending between the first end and the second end, a cross section of the second shell transverse to the longitudinal axis including:
- a first arcuate inner wall portion having a first radius of curvature, and
- a second arcuate inner wall portion having a second radius of curvature,
- wherein the first radius of curvature is larger than the second radius of curvature, and
- wherein the cross section of the second shell transverse to the longitudinal axis comprises a third arcuate inner wall portion and a fourth arcuate inner wall portion;
- wherein the process vessel is configured to form, from the composition, a solid fuel composition comprising an energy content of at least about 8,000 British thermal units per pound.
10 more elements
A method comprising:
- heating a composition within a process vessel, the process vessel comprising:
- a first shell;
- and
- a second shell disposed within the first shell, the second shell comprising:
- a first end;
- a second end;
- a wall extending between the first end and the second end;
- and
- a heating structure coupled to the wall, the heating structure configured to heat the wall, wherein the second shell defines a cavity to hold the composition during processing and a longitudinal axis extending between the first end and the second end, a cross section of the second shell transverse to the longitudinal axis comprising a first arcuate inner wall portion having a first radius of curvature and a second arcuate inner wall portion having a second radius of curvature, wherein the first radius of curvature is larger than the second radius of curvatures and wherein the first shell comprises a first outer end, a second outer end, and a first shell wall defining a cylindrical shape that extends between the first outer end and the second outer end;
- mixing the composition with first and second mixers disposed in the cavity of the second shell;
- extruding the composition with an extruder element disposed in the cavity of the second shell;
- and
- forming, from the composition, a solid fuel composition comprising an energy content of at least about 8,000 British thermal units per pound.
