http://thermogas.kiev.ua/SmallLogo.gif Gas CondOil - Process Simulation Software for Natural Gas and Oil Engineering

Functional Overview:

http://thermogas.kiev.ua/Small.gif The thermodynamic simulation of phase behavior in systems:

Vapor-Liquid

Vapor-Liquid-Liquid

Vapor-Liquid-Liquid-Solid (free salts)

The technological calculations are provided for following mixtures:

Gas

Condensate

Oil

Mineralized water

Methanol

Glycols (EG, DEG, TEG)

The following properties of gases and liquids are calculated:

Enthalpy

Entropy

Thermal capacity

Density

Viscosity

Thermal conductivity

Surface tension

PVT-Properties of reservoir oil

etc.

 

http://thermogas.kiev.ua/Small.gif Simulation :

- of the reservoir condensate and oil composition and properties taking into account of oil and condensate distillation data (recombination procedure).

- of the phase, hydraulic- and temperature behavior of streams in pipelines (horizontal, inclined, with variable level) transporting following single- and multiphase mediums:

Gas

Oil

Gas-water-oil

Gas-water-condensate

Unstable oil

Unstable condensate

etc.

 

http://thermogas.kiev.ua/Small.gif The technological calculations are provided for following processes :

Two- and three-phase separation

Throttling

Mixing

Ejection

Expanding

Compression

Heat exchange

Distillation

Absorption

 

http://thermogas.kiev.ua/Small.gif In particular following industrial systems are modeling:

Field transportation and gathering of natural gas and oil

Field-separation, glycol-absorption and oil-absorption processes

Reconcentration of glycols and methanol

Fractional distillation and stabilization of condensate and oil

Liquefaction of natural gas

etc.

 

http://thermogas.kiev.ua/Small.gif The thermodynamic calculations are provided for following values:

Hydrate-forming conditions and inhibitors expenditure

Vapor pressure

Reid vapor pressure

Water and hydrocarbon dew points

etc.

 

http://thermogas.kiev.ua/Small.gifThere are possibility of adaptation of GasCondOil-program to field and laboratory study data:

Stock tank oil or condensate density and viscosity

Saturated pressure of oil

Isothermic compressibility factor of reservoir oil

 

http://thermogas.kiev.ua/Small.gif GasCondOil - Program operates with following components of the mixtures:;

+ Fractions of Condensate (Oil)

 

http://thermogas.kiev.ua/Small.gifAdditional components:

Carbon oxide,  Ethylene,  Propylene,  Iso-Buthylene,  N-Buthylene,  1-Pentene,  1-Hexene,

1-Heptene,  1-Octene,  Acetylene,  Methylacetylene,  Ehylacetylene,  Dimethylacetylene  

 

http://thermogas.kiev.ua/Small.gifThere is possibility to enter and apply such laboratory data on narrow fractions:

Molecular mass

Density

Viscosity

Solidification temperature

 

http://thermogas.kiev.ua/Small.gifThe application limits of GasCondOil - Program are following:


Temperature:
 

70 °K < T < 700 °K


Pressure
 

0.003 MPa < P < 100 MPa


Fraction Boiling Temperature:
 

20 °C ÷ 700 °C

 

 

http://thermogas.kiev.ua/Small.gif Comparison of the GasCondOil-Program with HYSYS and PRO-2 show:

-       same accuracy for hydrocarbon mixtures;

-       better accuracy for hydrocarbons - aqueous solutions systems containing methanol, glycols and salts.
