Chemical Process Engineering – Concept to Conceptualization

The Process Design serves as the foundation of any chemical process. Once the throughput rate, product purities and yields are defined, Koch Modular chemical engineers begin the process of design conceptualization, wherein unit operations, system non-ideality, operating efficiency, process safety and capital costs are all considered and evaluated.

With the design concept established, Koch Modular develops an accurate model of the mass transfer system:

  • Selection of Equilibrium Data and Activity Coefficients
  • Development and Optimization of Chemical Process Simulation

Based upon the Process Simulation standard unit operation, heat and material balance, process flow and instrumentation diagram are created. Reliability, redundancy and flexibility are considered.

  • Process Flow Diagrams (PFD’s) with Heat and Material Balance
  • Piping & Instrumentation Diagrams (P&ID’s) with line sizing and pipe class specifications, instrumentation locations and process control schemes

Koch Modular process engineers next design the required equipment:

Column Designs including selection of mass transfer internals, hydraulic capacity and mass transfer efficiency.

  • Heat Exchanger Thermal Design
  • Preliminary Mechanical Drawings for Columns, Vessels and Heat Exchangers
  • Pump Hydraulic Calculations and Data Sheets

Finally, Koch Modular engineers together with our experienced piping designers develop three dimensional Equipment General Arrangement drawings incorporating the process’ flow requirements while optimizing accessibility for general operation and maintenance and in consideration of the available plant space.
