Scale-Up Processes

86
The scale-up of microbial fermentation processes is essential in industrial biotechnology, allowing the transition from laboratory-scale experiments to commercial-scale production while aiming to maintain product yield and quality. This process requires meticulous adjustment of equipment design, process parameters, and contamination control strategies to accommodate increasing culture volumes.At the laboratory scale, cultures are typically maintained in 1 to 10-liter glass or autoclavable...

Bioreactor Controls-II

57
In aerobic fermentations, oxygen is vital for microbial growth and metabolite production. Since air comprises only about 20% oxygen and the gas is poorly soluble in water—just 9 ppm at 20°C—supplying sufficient oxygen becomes a critical challenge, especially in high-demand processes like yeast growth or citric acid production. Even a fully saturated broth may offer only a few seconds of oxygen availability.To address this, sterile or scrubbed air is introduced into the...

    Area of Science:

    • Chemical Engineering
    • Energy Conversion
    • Waste Management

    Background:

    • Co-gasification of waste plastics and biomass offers a sustainable energy solution.
    • Dual Fluidized Bed (DFB) gasification is a promising technology for waste-to-energy conversion.
    • Scaling up pilot plant results requires careful consideration of process efficiencies.

    Purpose of the Study:

    • To assess the feasibility of co-gasification of plastics and biomass.
    • To predict the performance of a larger-scale DFB gasification plant based on pilot data.
    • To investigate the impact of reduced energy losses on fuel conversion in scaled-up gasification.

    Main Methods:

    • Pilot-scale co-gasification experiments were conducted in a 100 kW Dual Fluidized Bed (DFB) gasifier.
    • Scale-up predictions for a 750 kW semi-industrial DFB plant were developed.
    • An equilibrium model was used to simulate the effects of varying energy losses (70 kW, 115 kW, 160 kW) on fuel conversion.

    Main Results:

    • Successful co-gasification of plastics and biomass was achieved at the pilot scale.
    • Scale-up predictions indicated a simplified process with increased mass and heat flows.
    • Simulations showed that reduced energy losses significantly increase fuel conversion in larger gasification plants.

    Conclusions:

    • Co-gasification of plastics and biomass is a viable process for energy recovery.
    • Larger DFB gasification plants are expected to be more efficient due to relatively smaller losses.
    • Optimizing energy loss reduction is crucial for maximizing fuel conversion in scaled-up gasification systems.
