Abstract
Methods and apparatus for compact and easily maintainable waste reformation. Some embodiments include a rotary oven reformer adapted and configured to provide synthesis gas from organic waste. Some embodiments include a rotary oven with simplified operation both as to reformation of the waste, usage of the synthesized gas and other products, and easy removal of the finished waste products, preferably in a unit of compact size for use in austere settings. Yet other embodiments include Fischer-Tropsch reactors of synthesized gas. Some of these reactors include heat exchanging assemblies that provide self-cleaning effects, efficient utilization of waste heat, and ease of cleaning.
Claims23
A method for generating a chemical reaction product comprising the steps of:
- providing a reactor vessel including a top end, a bottom end, and a plurality of tubular heat exchanging assemblies located in an interior of the vessel, each tubular heat exchanging assembly having an outer diameter including at least one heat transferring fin;
- flowing synthesis gas into the vessel;
- converting the flowing synthesis gas into a chemical reaction product and heat;
- removing the heat by flowing a heat transfer media through each tubular heat exchanging assembly;
- and
- removing the chemical reaction product;
- wherein the at least one heat transferring fin is arranged to form a substantially unobstructed drip path for the movement of chemical reaction product in liquid form along said fin and toward the bottom end of the vessel.
A heat exchanging assembly, comprising:
- an outer tube having an opened end and a closed end, wherein an outer diameter of the outer tube is at least partially coated in a catalyst;
- an inner tube located at least in part in an interior of the outer tube and having first and second opened ends, the first opened end being located proximate the closed end of the outer tube, the second opened end being located proximate the opened end of said outer tube;
- wherein the outer tube and inner tube coact to provide a flowpath for a heat transfer media that extends between the outer tube and the inner tube from the opened end of the outer tube to the first end of inner tube and then extends internal to the inner tube to the second end of said inner tube.
