What is Mass Transfer? How can it help you save on your education?

WitrynaMass transport is in the form of either diffusion or convection. Diffusive mass transport is important in the main reactor and the afterburner. In these components, chemical or electrochemical reactions occur. Hence different species react to each other resulting in concentration buildup or depletion. WitrynaThe mass transfer rate is an important variable in the rate-based model. The most important variables in the mass transfer model are the diameter of the bubble and the bubble rising velocities. The lower the bubble rising velocity, the smaller the mass transfer rate is, and less variation in the compositions of methanol is obtained.
