Chemicals

Industrial production of important inorganic and specialty chemicals represent enormous financial products, and their production involves a broad range of fluidization unit designs and components.  Barracuda is being used to successfully understand all of the complex 3-D, transient fluidization phenomena in these units, including the catalytic chemical reactions inside large (>10 m diameter) deepbed reactors. Reactors types include acrylonitrile, titanium dioxide, and polyethylene. The fundamental understandings from Barracuda simulations has led to solutions for our customers, providing improvements regarding unit design modification, process flow modifications, scaleup from pilot plants, and ultimate chemical product yields.

In short, Barracuda ‘puts science behind your critical plant decisions,’ which have a large financial impact on your company.

Reactor Components → Issues

  • Sparger or risers → jet penetration / wear / location / number / geometry
  • Cyclones → efficiency / pressure balance / flooding / reliability
  • Feedline / Valves / Withdrawal → location, wear, number
  • Transfer Lines → size / orientation / wear / internals

Reactor Phenomena

  • Fluidization quality: bubbling to turbulent regimes
  • Gas bypassing or streaming in the bed
  • Particle attrition / agglomeration
  • Gas / solids contacting efficiency
  • Bed average density, DP/L
  • Segregation of size/materials
  • Elutriation rate / PSD
  • TDH / freeboard densities
  • Bed circulation rates
  • Chemical Reactions
  • Thermal performance of fluid / solids / coils
