CHEMPRO 9

Process Innovator

With CHEMPRO 9, flash calculations can now be done without the need for a complicated process simulator using THERMA Flash. CHEMPRO 9 includes all of the features of SiNET 9 and the Process Innovator. With the addition of THERMA Flash you can confidently determine the phase splits and properties of hydrocarbon stream without being a thermodynamic expert.

Fact & Accurate

Now you can become proficient in running flash calculations without needing to learn a complicated process simulator. There is no need to create feed streams, flash drums, and product streams graphically in a process simulator with CHEMPRO's THERMA Flash. Just select the type of flash calculation desired, enter the feed properties, and specify the stream composition. Quickly solve 2-phase and 3-phase flash computations for mixtures of pure and/or pseudo-components using the AIChE DIPPR database and API published methods. The three-phase flash engine determines the phase splits involving a vapor and two liquid phases. The flash drum on the main screen automatically changes from vertical to horizontal when 3-phases are predicted.

Thermo Expertise Build-In

CHEMPRO's THERMA Flash interface provides a visual representation of the feed and flash drum for entry of data. When feed conditions are entered, they are copied by default as the flash conditions that can be updated by the user. The Add Pure Components and Add Pseudo Components buttons at the bottom of the screen allow for selection and entry of either pure or pseudo components. Next, enter the mole percent of each pure and pseudo component. Select the Run Flash Calculations button to perform the flash calculations. Results of the phase split are shown on the screen in bold. Hovering the mouse pointer over any stream name will display a table of all stream properties. Select View Stream Properties to view properties for each phase that can also exported to Excel.

Pseudo Components

Pseudo components can also be automatically generated by entering either a D86, D2887, or TBP crude assay along with the API or Specific Gravity. The generated pseudo components and calculated mole percentages are automatically placed into the flash so that the phase split and stream properties of each phase can be calculated. A databank of accurate SRK and NRTL parameters is included that is automatically selected for component pairs -providing high quality 2-phase and 3-phase flash results. Select the View Binary Parameters button to display the coverage of binary parameters and to add your own custom parameters.
