Case 15003

Fischer Tropsch Reactor with Integrated Organic Rankine Cycle

Keywords:

Fischer Tropsch synthesis, coolant, recycle,

Applications:

Fischer Tropsch Plants

Problem:

    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.

Technology:

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.

Advantages:
  • 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.
