Alkylation

ProMax’s new Alkylation block enables the user to simulate complete HF and Sulfuric Acid Alkylation units in a single simulation! Let our staff help you construct and solve these complex models, allowing you to get to the real problem solving you need.

Overview

ProMax® Alkylation
  • Select either HF or Sulfuric Acid alkylation reactors with predefined kinetic parameters
  • Model both Actively Cooled or Adiabatic Reactors
  • Calculate inlet iso-butane/olefin ratio as well as acid/hydrocarbon ratio
  • Utilize 18 different simultaneous reactions specific to alkylation
  • Perform dependable flashes with industry leading VLLE predictions

Thermodynamics

Upgrades to Acid/Hydrocarbon and acid/water VLLE allow for accurate simulation of associated separation, fractionation, and refrigeration processes. The thermodynamic enhancements make the simulation of HF Acid Regenerators accurate and easy.

  • Predict HF/H2O azeotrope accurately using the specialized Polar PR or Polar SRK
  • Calculate alkylate properties, including RON, RVP, %C9+, and D86 values
  • Analyze the distribution of acid in cases of acid carryover from the settler
  • State of the art GHOSH method for Ron Prediction
  • Sulfuric Acid/Hydrocarbon distribution in VLLE systems
  • Sulfuric acid strength management
