Chemical Industry decisions are based on data and calculations. Chemical Processes are also best understood with quantification of the process parameters. For example to decide propane vessel design pressure, one needs to know propane vapor pressure.

This Calculator provides users data and established models to calculate parameters required in the chemical industry decision making process.

The Calculator is divided into Four Main Sections.

1) Unit Converter
(Conversion of units frequently used in chemical industry. FREE)

2) Equipment Sizing
(Sizing of equipment frequently used in chemical industry. PAID. Promotional price.)

3) Component Properties
(Data of 230 components frequently used in the chemical industry. PAID. Promotional Price.)

4) Mixture Properties
(Calculation of mixture properties frequently used in the chemical industry. PAID. Promotional Price.)
