OilProp is designed to assess the core thermalphysic
properties of oil and its derivatives necessary to
solve transportation and processing tasks, with the
minimum volume of input data. It is based on
regularities and statistics generally known in the
area. OilProp solves the following tasks:
1. Basic Calculation - calculation of thermalphysic
properties at the atmosphere pressure and the
temperature 20 deg.C (68 deg. F).The calculation
results are used for hydraulic analysis of pipelines
as well as in design of equipment intended for
storage, thermostating, transportation, mixing,
spraying homogenization of oil and its derivatives.
Density and / or fractional composition of the
substance are used as input data (the calculation is
more precise if fractional composition is given).
The program calculates density (if not given),
isobaric specific heat, thermal conductivity,
kinematic viscosity, average saturated vapor
pressure, surface tension, the Prandtl number, and
pseudocritical temperature.
2. Additional Calculation - calculation of
thermalphysic properties of a substance in liquid and
gas phases at given absolute pressure and temperature
within the under-critical range. The calculation
results are used for process modeling and design of
equipment intended for processing of oil and its
derivatives, for hydraulic and aerodynamic design of
pipelines at steady and non-steady temperature, as
well as to find out heat exchange process
characteristics, etc.
Additional input data, besides temperature and
pressure, are density and/or fractional composition
(calculation is more precise when fractional
composition is given).
The program calculates the percentage of liquid and
gas phases, density, isobaric heat, thermal
conductivity, vaporization enthalpy, kinematic
viscosity, surface tension (for the liquid phase
only), and the Prandtl number.
