KBI’s Modeling & Simulation Capabilities

Mechanistic Modeling

  • Mechanistic models leverage scientific and engineering knowledge to develop a mathematical description of the fundamental processes occurring within the unit operation

  • These models typically require some experimentation to define model parameters, after which predictions can be made with respect to unit operation performance over a wide range of operating parameter conditions

  • Mechanistic models can be used for process optimization, evaluating process robustness, and fully characterizing the performance of the unit operation within a specified operating space

Process Modeling

  • Process modeling utilizes mass and energy balances combined with information about the process and production facility to understand process and facility fit

  • Costs for raw materials, capital, labor, and disposables are then incorporated to calculate the overall cost of goods

  • Application of process modeling during process development is essential to ensuring a cost effective process

Computational Fluid Dynamics

  • Computational fluid dynamics (CFD) is a first-principles technique in which the differential equations describing fluid, mass, and heat transfer are solved computationally for a fluid contained in a specific geometry

  • CFD can be used to characterize mixing in process vessels, estimate gas mass transfer in bioreactors or understand flow distribution in chromatography columns

  • This technique is most beneficial in situations where taking experimental measurements is very difficult or expensive and a more complete understanding is required for successful process scale-up or transfer

Plant Simulation

  • Plant simulation combines process and facility information (process sequence, process timing, equipment availability, etc.) into a mathematical framework that enables optimization of facility run rate via constrained optimization techniques

  • Plant simulation is used to understand the impact of process, equipment or operational changes on the maximum run rate of a facility as well as to support finite scheduling in manufacturing

  • Application of plant simulation ensures the process you are developing or the facility you are designing will deliver the capacity target you expect
