Improved energy efficiency of reactors used to convert carbon monoxide and hydrogen into liquid fuels.
Fischer Tropsch Plants are the major application.
Fischer Tropsch reaction is exothermic, requiring rapid removal of low grade heat to avoid catalyst damage and ensure desirable product mix. Heat removed from the reaction is often wasted.
This technology is comprised of an Organic Rankine Cycle that uses a product stream from the Fischer Tropsch reactor as its working fluid to convert the low grade reactor heat into shaft work within the plant.
- Good conversion efficiency of low-grade heat into shaft work
- Immediate source of working fluid such that organic fluid can be continuously recycled to maintain integrity of the working fluid.
- Leaks between the shell side and the tube side of the reactor have little consequence.
