Description
Alph is a process calculator for the iPhone and iPod Touch 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.
Two and three phase flash calculations are supported, along with two phase envelopes and hydrate temperature and pressure prediction, wit

The Natural Gas edition of Alph uses VMG's Advanced Peng-Robinson for Natural Gas package and a slate of commercially important natural gas compounds:
C1-C10, iC4, nC4, CO2, H2S, N2, O2, H2O, H2, He-4, methanol, ethanol, ethylene glycol, diethylene glycol, triethylene glycol, methyl mercaptan, ethyl mercaptan, carbonyl sulfide, carbon disulfide, dimethyl sulfide and dimethyl disulfide.
Custom compounds, such as heavier fractions, can also be defined.
A free version called Alph Jr. is also available. It has all the capabilities of the Natural Gas edition, but is limited to the straight chain alkanes methane through decane. This is suitable for becoming familiar with Alph's capabilities and for instructional and learning purposes.
