Development of a Polyacrylic Acid Production Facility

  • Co-leader of a team that developed a 2.5 million process for the continuous production of aqueous polyacrylic acid.
  • Led the development of all fundamental thermodynamic and kinetic data, design and sizing of the primary Continuous Stirred Tank Teactor (CSTR) and a post reaction Pressurized Flow Reactor (PFR) used to chase residual monomer.
  • Led design of a stripping column for treatment of SO2 from the product stream and development of the computer simulation of the process conditions to modify product properties for different customers.
  • Process was taken from initial concept, through laboratory batch reactions, to commercial production startup in nine months.

Nanofiber Devolatilization

  • Lead consultant on the development of new stripping processes for the removal of residual spinning solvent from nanofibers produced via commercial scale spinning operation.
  • Responsible for development of fundamental transport data and models used as a basis for the design of the commercial stripping unit.
  • Team member of the design team, responsible for overseeing the choice of stripping conditions, residence time requirements and P&ID reviews.

Polyacrylonitrile "Noodle" Production

  • Lead consultant and design contractor for the development of a facility to produce "noodles" made from polyacrylonitrile.
  • Polymer is soluble in a highly concentrated proprietary mixed-salt solution that enables the material to be extruded into noodles resembling cooked spaghetti. Product is used for medical applications.
  • Responsible for development of fundamental design data, preliminary process flow diagrams, development of concepts, laboratory testing of separation and purification processes, and development of design data and P&IDs for drying and packaging the product.

Tyvek Spunbonded Devolatilization

  • Lead consultant on the development of a new stripping process for the removal of residual spinning solvent from Tyvek sheets produced with a new spin solvent.
  • Responsible for development of all fundamental transport data and models used as a basis for the design of the commercial stripping unit.
  • Team member of the design team, responsible for overseeing the choice of stripping conditions, residence time requirements and P&ID reviews.
