👉 The sending fluid, also known as the ejector fluid or driving fluid, is a critical component in a fluidized bed reactor system, particularly in processes involving gas-solid reactions. This fluid is typically a low-pressure liquid or gas that is pumped through the reactor bed, where it interacts with solid particles suspended in the gas stream. The primary function of the sending fluid is to enhance mass transfer and improve heat transfer within the reactor by promoting better mixing and reducing pressure drop. By continuously moving through the bed, it helps in maintaining a uniform temperature and ensures efficient reaction kinetics, ultimately leading to improved product yield and quality.
