Structure of Reforming Process Model

The reforming process model is designed to predict the performance of many reactor configurations. The model can be run in four modes, combining adiabatic or isothermal reactors with recycle or single-pass (no recycle) 

Module INPUT takes user-specified input and constructs proper initial conditions for the detailed mass and energy balance equations. 

To specify charge stock characteristics, one of several options can be used specify a detailed gas chromatographic composition call the naphtha library estimate composition from general charge stock properties, such as PON A (% paraffins, olefins, naphthenes, and aromatics) and gravity or blend up to seven naphthas by utilizing the naphtha library. 

The module REFORMER constructs the user-requested simulation and controls the numerical calculations. It simulates the process scheme and 

The module FLASH simulates the reformer flash separator by using a modified Chao-Seader method. The necessary constants for the Chao-Seader correlation have been developed for the lumped components. The output from this module determines the liquid yield and the composition of recycle gas.
