• Stream names were limited in length 16 characters. This has been increased to 40.
• Error codes returned a "TOO MANY SPECIES" error when the pseudocomponent name length was too long. The error codes have been updated to make more sense.

Announcing the release of ScaleChem 3.2

Scalechem 3.2 has been updated to the ESP v7.0 code base and databases. The user interface remains the same

• The molecular weights for the anions and cations in earlier versions were rounded off to only a single decimal point. They have been expanded to match the same significant digits reported in ESP
• Persistent Bug! The units of molality for brine input does not properly reconcile water. It is recommended the this unit set not be used. There are no plans to repair this bug at this time.

OLI Security module updated to allow for 64 bit operating systems.

A bug was found that when pseudocomponents from an assay were saved as a new oil sample, some of the internal names became disconnected from the chemistry model. This has been corrected

A minor bug in duplicate species names were found in files that were opened from version 3.0 of the software. This serves as a warning. This bug will not be fixed. You can still open the file and manually copy out the species information to create a new object in the same document.

The test case files distributed with the software were brought up to version 3.1.18. The values may be slightly different than what is in the standard ScaleChem documentation.

03.24.2006

The Get Name dialog has been changed. You do not have to select "new" for a new brine. You can either enter a name or allow the program to generate a new name for you.

A warning is now displayed if you attempt to enter a name with an illegal character. The program automatically renames the object.

Old cases with illegal names are converted. The name is changed and a prefix of CVT_ is added to alert the user that name has been converted.

Bug Fix: Spaces in the brine, gas and hydrocarbon name were not properly trapped. This created an invalid record in the SIN file. Only allowed characters are A-Z, a-z, 0-9, '_', '-'. The first character must be A-Z or a-z

Enhancement: You can now rename an object in the tree-view by right-clicking and selecting Rename.

Enhancement: You can now drag-drop items from the base tree in the tree-view to a well designation. The reverse trip is not possible.

Enhancement: Copy of objects within the tree using drag-drop is now supported (Hold Control while dragging)

An error was made in fixing duplicate species names in the brine reconciliation screen. Names of ions, such as Na+1 was changed to NA1. The name NA1 does not exist in the OLI databases. The mapping routine was updated.

General update to security to improve licensing options

Error’s in using petroleum assays were fixed. The assay name must have the first five (5) characters be with any special characters such as “-./,_,%, etc”

Added a general tab to options to allow the document directory to be specified.

Also now honor the document directory when displaying file save on a new document. File save as will default to directory where document is currently saved.

The delete key occasionally did not function correctly when editing a cell in a grid. This has been fixed in this build.

You can now move a calculation from a base position on a tree to a well after it was created. Prior to this bug fix, once an object was created, it was stuck in the place were it was created.

Duplicate names for neutral species was fixed
