The OLI ScaleChem - Standard program was originally designed with a limited number of solids to be considered. In the OLI software each solid is considered to be an individual phase. Each phase is then tested to see if it may exist. We use our Scaling Tendency algorithm to evaluate if a solid should exist. Testing for each solid increases the run-time of the calculation.

In the 1990's computers were not as powerful as they are today so limiting the maximum number of solids keep the computation time at a reasonable level. OLI ScaleChem - Standard was limited to only 6 solids. As time went on this was expanded to 9 solids. with the advent of more powerful computers the number of solids in OLI ScaleChem - Standard was increased to 58. This number of solids could be evaluated easily and covered the majority of solids found in upstream oil and gas production.

To differentiate between the solids in the original program and these new solids the terms of Standard Solids and Expanded Solids were introduced. The term Standard Solids refers to the original 9 solids and the term Expanded solids refers to the additional 49 solids added.

We have a listing of all the solids in OLI ScaleChem - Standard and which solids are designated Standard or part of the Expanded list. All solids marked as True in this list are part of the standard solids and all other solids are part of the expanded list.
