The National Energy Modeling System: An Overview 2003

Refinery Processing Units Modeled in PMM

Atmospheric distillation, vacuum distillation
Delayed coker
Fluid coker-includes flexicoking mode
Fluid catalytic cracker (FCC)-includes distillate, vacuum gas oil, coker  gas oil,    atmospheric residual, unallowable feeds; conversion ranges 65 to 85 percent;    ZSM  catalyst mode, low severity mode
Gas oil hydrocracker (including advanced technologies)
Residuum hydrocracker
Naphtha hydrotreater
Distillate desulfurization
FCC feed hydrofiner

Catalytic reforming-separate units for semi-regenerative  high-pressure, low-
   pressure cyclic; severity range as appropriate to the reactor; allow light straight    run  through heavy naphtha virgin streams, heavy naphthas from FCC, coker,    and hydrocracker operations; allow new highly active catalyst operation
