Current issues with OLI Flowsheet: ESP (Beta)
Here are some of the known issues with the OLI Flowsheet: ESP (Beta) program.
Contents
General Information
Databanks
OLI has changed the format of the OLI databanks from the original 39 files developed for the FORTRAN code to a single SQL file. This makes maintaining the software much easier. However, it will require any users that have ESP databanks to convert them to the new SQL format. A tool has been provided under the OLI Flowsheet program group.
Chemistry Models
Multiple Models
Multiple models are supported in OLI Flowsheet:ESP but the model file view will only display the master model regardless of the tab which has focus. This will be resolved in a later build.
Pseudocomponents and Assays
Assay and pseudocomponent names are remapped to a nonspecific name in the model file. For example, in ESP Original the assay name CRUDE would generate the pseudocomponent cut names (based on distillation data) of the type CRUDE_273K, CRUDE_283K,etc. In OLI Flowsheet: ESP the name becomes UD_273K. This should not be a problem because the name is properly remapped back in the reports and output calls. Only debugging tasks will see these remapped names.
Unit Operations
Current Support Status
There are many unit operations in the ESP Original program. Most have been or will be implemented in OLI Flowsheet: ESP. Some unit operations are not yet ready but are planned for inclusion. Other unit operations are not planned for inclusion in the software since OLI's business interests have migrated away from those areas.
These undeveloped unit operations will continue to be supported in the ESP Original program.
Those unit operations in the third column Future Development which are blank are planned for inclusion but have not yet been scheduled for development.
