The design and scale-up of multiple-impeller fermenters for liquid film controlled processes

Popis výsledku v původním jazyce

Mechanically agitated gas-liquid contactors are frequently used in the chemical, food and biochemical industries as fermenters and as hydrogenation or chlorination reactors. However wide the usage of such vessels is, their design is not based on chemicalengineering data, but is still rather empirical. Thus, it is highly desirable to have a tool for the rational design of agitated gas-liquid contactors that is based on fundamental chemical engineering parameters that are transferable to other systems and operating conditions. Focusing on liquid film-controlled processes and using the data from fermenters of different scales, we develop kLa correlations that are suitable for scale-up. First, we discuss the way how to determine the proper experimental kLa values, which are not distorted by other equipment parameters as the gas residence time is. We demonstrate the possible kLa distortion on the pilot-plant experimental data by the comparison of the results obtained by two different exper
