Process Concept for Scaling-Up and Plant Studies

• This article deals with the concept of scaling -up and scaling -down of industrial processes which is an essential requirement to understand and optimize the process. The concept has been described based on physical modeling of the process at laboratory scale using various techniques. The concept of physical modeling has been followed by two industrial examples where it has been used successfully. First example deals about scaling down of an industrial process to a laboratory scale to understand the raceway formation phenomena in an iron making blast furnace. In second example development of a new process for Mo addition in EAF practice is described. The development starts from theoretical backgrounds for the process of Mo addition improvements and then follows with number of experimental trials starting from 16g laboratory scale furnace to 70 ton industrial EAF.
