ProTreat Version 3.14 has now been released. It includes several significant improvements. Not the least is three times faster convergence over what was already record convergence times, plus even greater robustness.

Tray hydraulic calculations are more detailed in Version 3.14 so that the selectivity enhancement from low-weir-load hydraulics can be more easily applied. Mass transfer and wetted areas of structured packings are now calculated from state-of-the-art models. For anyone working in carbon capture, accurate packing models are essential.

Improvements to reaction equilibrium calculations give a very close match to GPA heats of absorption as a function of temperature and acid gas loading. This has also resulted in nearly perfect agreement with a large heat capacity literature (+/- 2%), with proper account taken for the effect of acid gas loading on heat capacity and other properties.

AMP, an interesting solvent for CO2 capture, has been added to the amines database, and data on piperazine and the GAS/SPEC solvents have been updated, including the addition of CS-1160.

A fully-customizable stream summary table is now available for on-screen viewing, for copying to the clipboard, and printing to Excel and Word. You can also now open multiple plots showing column profiles of composition and properties simultaneously. And flowsheets with up to 25 columns and 500 streams are now easily solved in record times.

Licensed customers can download Version 3.14 by going to the Support area of this Website and entering their HASP Key's ID to gain access to the downloads page.

A Demo Version is freely available for download. Just click on the Demonstration button. In addition to showing you typical data input and simulation results, the demo version can be used to read and manipulate ProTreat simulation results files generated and sent to you by licensed users.

Several new publications dealing with super-enhanced selectivity for trays in the spray regime, and with column design for CO2 removal using MDEA (Petroleum Technology Quarterly, Gas) are available for viewing and download from this Website.

Finally, OGT offers seminars in Advanced Gas Treating that provide you with the kind of insight needed to solve challenging problems. These three-day seminars are held twice-yearly in Houston and annually in Baden-Baden, Germany. Just click on Seminars for detailed information on dates, venues, and content with depth you will find nowhere else.
