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

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
