Novel Models / Simulators for Refinery Processes
FCC-MOD

Features and Capabilities

» A rigorous model based on four lumps cracking reaction kinetics and first principles
» Consists of models for all sections of FCC process
» Model has been validated extensively with industrial plant data

FCC-MOD Model for FCC Process

» Model capable of predicting the plant performance for wider range of feed quality and operating regimes
» Model can be used for various applications such as
  • Optimization of commercial plant performance for new catalyst/additive evaluation
  • Day to day monitoring of FCC unit
  • Minor hardware revamp study
» Real time applications
  • Throughput maximization in one of IndianOil FCC unit keeping conversion constant
  • New catalyst selection on regular basis for IndianOil FCC units
  • Hardware revamp study for non-IndianOil FCC units
HC-MOD

Features and Capabilities

» Rigorous hydrocracking kinetic model based on continuum theory of lumping approach
» Configured for once through and recycle HCU
» ASTM D-4625
» User friendly GUI
» Estimation of effect of all critical feed properties, changing operating conditions, etc. on yield patterns and Reactor's CAT
» Preliminary profitability calculations
» Preliminary deactivation module

Applications

» Simulation studies for process optimization, i.e. selection of optimum operating parameters for maximization of desirable product slates
» Commercial hydrocracker units troubleshooting
» Effect of changing feed mix or feed properties on the operation of commercial unit
» Data generation for tuning of LP model
» Catalyst's health and remaining life assessment
» Day-to-day performance monitoring of unit
» Improving the conversion in commercial hydrocracker unit
» Licensor failed to solve problem of negligible conversion in 2nd stage of a two stage recycle hydrocracker unit which the above model could solve
