Components

SimTech Simulator already has a pure component library of more than 2,500 components, which can be used for K-value and other property calculations. It supports functions such as custom components, parameter regression, and parameter estimation.

Crude Oil Fractionation

Support the fractionation of distillation curves such as TBP, D86, D1160, D2887, etc., including: distillation curve conversion, specific gravity curve generation, calculation method of standard boiling point of fractionation components, calculation of critical properties and ideal gas enthalpy, molecular weight calculation method, and setting of true boiling point distillation curve cutting points, etc.

Thermodynamics

There are 37 thermodynamic methods, including commonly used property methods such as SRK, SRK-KD, PR, NRTL, SRKM, PRM, PSRK, UNIQUAC, UNIFACChao-Seader, Grayson-Streed, BraunK10, etc.

It also supports APl Density, Lee-Kesler, NRTL-PR, NRTL-SRK, Regular Solution, UNIFAC-PR, UNIFAC-SRKUNIQUAC-PR, UNIQUAC-SRK, COSTALD, Crul-Pitzer, IGS, Glycol, Li-mather, Sc02Sour-Water, Sulfolane, Sulfolane2, HCR, and NRTL-HOC, etc.

Unit Modules

There are comprehensive unit operations, such as flash, valve, compressor, expander, pipeline, pump, mixer and separator, distillation tower, heat exchanger, strict shell-and-tube heat exchanger, air cooler, cold box model, reactor, etc.
