AQUAlibrium 3.01 is a software package for systems containing water, hydrogen sulfide, carbon dioxide, and light hydrocarbons. It has a well-deserved reputation for being amongst the most accurate software for equilibrium calculations in these systems, especially for acid gas + water systems.

What's New

The following items are new in this version over AQUAlibrium 2.0:

• New calculation routines
• Phase equilibrium calculations for mixtures that do not contain water
• Calculations of the enthalpy, heat capacity, viscosity, and thermal conductivity
• Win32 MDI Interface
• Project and file management of AQUAlibirum calculations
• Documentation of AQUAlibrium projects
• Exporting of the AQUAlibrium projects to other Windows applications

Calculations

There are six major groups of calculations:

1. Pressure-Temperature Flash
2. Water Content
3. Vapour-Aqueous Liquid Dew Point (Pressure or Temperature)
4. Non-Aqueous Liquid Dew Point Pressure (Normal or Retrograde)
5. Non-Aqueous Liquid Bubble Point
6. Solubility

Components

Currently, there are eleven components built into the programs:

The seemingly small component list currently in the program (compared with general purpose simulators, for example) is because the necessary binary systems have been thoroughly studied by the author and, based on this work, he has confidence that AQUAlibrium is the best available software for these systems.

Installation

The AQUAlibrium Installation Wizard will lead you through the installation process. Those familiar with such wizards should have no problem with the installation.

System Requirements:

• Pentium Processor
• Microsoft Windows 98/2000/Me/NT/XP
• 10 megabytes of space on hard drive
• Options: In order to make best use of AQUAlibrium 3.0 the following applications should be installed:
  • Microsoft Word 97 or later
  • Microsoft Excel 97 or later
