Riser Reactor

Riser reactor or Circulating Fluidized Bed (CFB) is one of the most crucial high-tech equipment used in the chemical, mineral, processing, pharmaceutical and metallurgical industries. It produces about 30% of the world's gasoline and generates about 30% of Europe's power. A riser reactor is a tall vessel, about 1-2m in diameter and can be about 40m high. Its main purpose is to carry particles up the pipe, through an upwards flow of fluid. It might sound very simple, yet there are many reactions that can occur within a CFB. With an increase in global demand of production rates of fuel and power generation, this study was made to understand the hydrodynamics of CFB for better design, scale-up and optimisation of processes.
