ProTreat v8.1
Optimized Gas Treating, Inc. is pleased to announce the release of ProTreat® Version 6.5.
Advances include:

Custom Excel Reports allow the user to export ProTreat's results into highly customizable spreadsheets.
New Clariant solvent:
Genosorb® 1753 - Optional, special license required
New DOW solvents:
UCARSOLTM HS-103
UCARSOLTM AP-804
UCARSOLTM AP-806
UCARSOLTM AP-810
UCARSOLTM AP-814
New packings offered:
New packings: Raschig Super Ring Plus and Sulzer NexRings
Updated some Sulzer packings based on feedback from Sulzer
Hydraulics for Sulzer packings are now calculated by a DLL supplied by Sulzer
Major update of MDEA and Piperazine thermo
Incorporated recently published and collected data into updated model
Performance of some columns using MDEA, Piperazine, and their blends will change with respect to treated gas composition, lean / rich loading, and absorber temperature profiles
Refit and Update of mass transfer model
Mass transfer characteristics of CO2 were updated
Viscosity of some CO2-loaded aqueous amines has been refitted
Some characteristics of heat and mass transfer for trays have been updated
Thermodynamic packages have been renamed:
"Deshmukh-Mather" is now called "OGT Gas Treating"
"Non-Ionic" is now called "Physical Solvents"
"Sulphur" remains unchanged
The "ProTreat Decides (Non-Sulphur)" option has been eliminated. Blocks which previously used this option will be automatically changed to whichever package is set as the Global Thermo Package.
Completely new and improved warning system which eliminates pop-ups and graphically indicates which blocks / streams have warnings associated with them. Warnings are saved and viewable in result files.
Solver Blocks now offer several new usability improvements:
Solver restarts greatly improve execution time for previously converged flowsheets
Linear and Quadratic Search with Optional Limits project the adjust variable to meet the target specification
Available solver connection points automatically appear when drawing the adjust or target variable connection stream
Inlet Blocks now allow the user to specify the vapor fraction of a stream. Streams can be specified at their dew point, bubble point, or any vapor fraction in between at a specified temperature or pressure.
Column Block
Reboilers now allow specification of a Reboiler Temperature or a Reboiler Molar Boilup Ratio
Sections can be deleted or duplicated
Improved default segmentation for packed columns
Packed column segmentation can now be specified as the total number of segments or as the height of a single segment
Improved downcomer choke predictions
New Column Reporting Features
Heat Capacity Ratio (HTCR) is now available as a column result. This parameter assists in analyzing the operating regime of the column, as discussed in recent OGT publications.
Enthalpy, Moles absorbed for each component, and Dry Gas Dewpoint can be calculated and reported for every segment
Total Segment pressure drop is reported for every segment. Trayed segments also report Dry and Wet components of the total segment pressure drop
Control Blocks now offer different options for calculating make up / purge rates. Make up and purge can now be represented as material streams.
Molten Sulphur viscosity is now calculated using the more accurate ASRL correlation
Stream Names are now displayed on the flowsheet drawing and in Custom Excel Reporting
Usability Improvements:
Column temperature graphs can now be disabled during execution
Streams in a results file can be copied to a new Inlet or Recycle block
Users can now customize the order of components
Multiple compositions can now be pasted into Inlet / Recycle / Control Blocks as blocks of values
Stream and Block names can now be hidden from the flowsheet display using controls under Setup
Updated and expanded list of COM variables
Column results now include the Minimum and Maximum Temperature in the column. This will assist in monitoring the column's operation against limits that may be of interest to the user
Licensing/HASP tools are now integrated into the GUI
HASP key updates or drivers can be applied or installed through help links
Softkey licenses can be set to auto login and logout as the GUI is launched and closed, respectively.
