Single-Course English 5 ECTS

Industrial BioReaction Engineering

Overall Course Objectives

The reactors used in the bio-industries are designed according to the same general principles as those elsewhere in the chemical industry. However, there are some specific characteristics of bio-reactions (fermentation) which require specialist treatment, such as the variable stoichiometry and complexities of scale-up. Using a quantitative approach, fermentations are analyzed with respect to feasibility and scale-up for the production of a range of bio-based products (including cells, proteins and chemicals). A variety of feedstocks (including waste sugars and gasses) as well as production technologies (including two-stage fermentation) will be discussed. Emphasis will be placed on bioprocess economics and industrial implementation.

Learning Objectives

  • Describe the role of fermentation in the context of bioprocesses for production of industrial products (including cells, proteins and chemicals).
  • Calculate mass balances for fermentations, including gas-liquid mass transfer
  • Calculate elemental and redox balances for fermentation processes
  • Evaluate the feasibility of fermentation processes in an industrial context and devise a research/development plan
  • Analyze the consistency of experimental data using simple models
  • Evaluate productivity requirements of large-scale fermentation
  • Calculate the heat of production of aerobic fermentation process
  • Describe the principles for design and scale-up of a bioreactor
  • Describe the role of two-stage fermentation and in-situ product removal in the context of bioprocesses for production of industrial products
  • Evaluate simple downstream concepts from fermentation processes
  • Evaluate simple economic models of bioprocesses.
