Alph is a process calculator for the iPhone, iPod Touch and iPad based on the world class thermodynamic and physical properties calculations of VMGThermo, which is the Virtual Materials Group package that powers their comprehensive process simulator VMGSim.

Alph Jr contains all of the features of Alph, but with a limited compound selection and no ability to purchase options. Some important features include:

• VMG's Advanced Peng-Robinson equation of state package

• two and three phase flash calculations

• two phase distillation with multiple feeds and draws

• hydrate temperature or pressure prediction

• a multivariable nonlinear equation solver.

• light hydrocarbon compounds C1-C10 (additional compounds are available in the full Alph version).

Alph is not a traditional process simulator, but rather a sophisticated calculator that eschews the classic stream and unit operation model in favour of an information flow model that uses powerful, but simple, spreadsheet like formulas to define the relationships between fluids and powerful tools like distillation towers, phase envelopes and multivariable equation solvers. The web site has numerous tutorials and examples that illustrate its flexibility and power.

What's New in Version 1.5.3

⦁ Added Volumetric Flow (actual) as a display option.
⦁ Allow the use of most VMG unit types in "fromunit" and "tounit" formula functions, in addition to the existing display option types.
⦁ Added a formula function "u" as a shortcut name for "fromunit".
⦁ Added a help page listing the available unit types and units.
⦁ Object names on the diagram are now in italics if the object has notes.
