Overview of the 2014 OLI Simulation Conference

A review of the 2014 OLI Simulation Conference.

OLI held its 2014 conference at the Wyndham Hamilton Hotel and Conference Center in Florham Park, New Jersey from Monday October 20 to Wednesday October 22. It was actually 5 sessions:

  • Review of the Mixed Solvent Electrolyte project (Monday October 20)
  • Review of the Corrosion Simulation Code (Monday October 20)
  • Corrosion in Refining Overheads (closed session, Monday October 20)
  • OLI Simulation Conference (Tuesday and Wednesday October 21 and 22)
  • Ultra High Temperature High Pressure Consortium meeting (Closed session Tuesday October 21).


Details of the presentations can be found on the main OLI website (authored by AQSim).  I will only point out the highlights.

There were many excellent papers presented by users of OLI software. Rusty Strong (Athlon) presented a paper where he stated “I did not know if this would work but I did not ask OLI first.” As an employee of OLI I got really nervous about statements like that. Rusty’s work showed that we worked and worked well. Whew…

The OLI side of the conference was pretty much the same as we usually do it. Marshall Rafal (Present and Founder) presented a nice heartwarming speech about the history of OLI and its future.  He correctly identified three generations of OLI Employees.

  • First Generation
    • Marshall Rafal
    • Jim Berthold
    • Robert Young
    • Pat McKenzie
  • Second Generation
    • Andre Anderko
    • Margaret Lencka
    • Peiming Wang
    • Ron Springer
    • Chris Depetris
    • Jane Mooney
    • Sandy Hogan
    • George Englehardt
    • Warren Shen
  • Third Generation
    • Jianping Liu
    • Prodip Kundu
    • Rasika Nimkar
    • SachinDaluja
    • Zousho Lu
    • Yan Ramlakhan
    • Denize Llerna

I was quite pleased (and a bit dismayed) that I am in the first generation. I guess I am getting old.

Many of the OLI Staff presented during the conference.  Several others presented demonstrations during the breaks.

Of perhaps the most important (in my not-so-humble opinion) was the presentation and demonstration of OLI Flowsheet by Sachin Daluja.  This was an impressive piece of work. I am amazed at how fast Sachin has created this code. To give him credit, I have full faith in his skills that he could have created a working code.  This wasn’t just any demo-ware. It is a full functioning Flowsheet simulator. Of course it needs many features to be added.

If you are interested in becoming a beta testing in 2015 for OLI Flowsheet please let me know.

Also demonstrated were the OLI Studio by Warren Shen, the OLI API (interface to Excel) by Zousho Lu and our new wikipedia page by Rasika Nimkar.  All did very nice demontrations.

OLI has a Wiki!

OLI now had a wikipedia page that we host internally. Here is the link wiki.olisystems.com

This site is still in its infancy but it is growing.  We are moving away from the old OLI support website as it is rapidly becoming outdated. The Wiki is much easier to maintain.  Beside OLI, AQSim is also a contributor to the wiki pages.  As time progresses we may allow end-users to add to the wiki. Time will tell.

Future Release?

Many users asked when OLI will release the next version.  The next version will be 9.2.1 of all the products. We are currently waiting some last minute data work to be completed. When that occurs it will be about 2 weeks to publish the version. Of course OLI Studio is published first, followed by ESP Original, ScaleChem Standard, Alliance Products, Developer Edition, and any others.  Each gets tested.

I would anticipate December 1, 2014 for the release but don’t hold me to it.


That’s all for now,

Jim Berthold



OLI Releases New Software (again!)

OLI Systems finally releases updated software.

It has been quite a trial to release this new update of the software.  I will not bore you will the details but we had some problems with the numerical engine.  Since our last series of blogs back in 2010 we have changed the way the software works.  The core of the software is called the Engine and it is the same for all of our products.  There is a single solver and a single database (per version) across the board for each product.  Long-time users of the OLI Software will recall that the OLI Analyzer had a separate installation location for the database than did OLI ESP.  This is no longer true. Only a single location exists for the database.

For all the versions of 9.1 this location of the database is:

C:\ProgramData\OLI Systems\Databanks\9.1.4

The current version of the software is version 9.1.5 so why is the the database location 9.1.4?  We for the current version of 9.1.5 we did not update the database.  In fact there could be many versions of the database installed on your computer. You have the option of using previous versions.  Here is what the database folder looks like on my computer.


You can see that I have a lot of versions installed.

OK, what got released?

The current base version is 9.1.5.  Here is what got released (along with the corresponding release notes link)

OLI Studio  9.1.5

ESP Classic 9.1.5

Aspen PLUS V7.3, V7.3.2, V8.0, V8.2, V8.4 and V8.6

Aspen HYSYS V7.3, V8.0, V8.2, V8.3, V8.4, V8.6

Unisim Design R410 and R430

What’s not supported any more?

We can’t do this forever…

Aspen Technologies has stopped supporting their products that are more than 4 versions old.  Since V8.4 is the “Official” release, no version before V8.0 is supported by Aspen Tech.  OLI Systems is not taking quite as a draconian view, we will support the versions listed above.  We have stopped supporting Aspen PLUS/HYSYS 2006.5 and earlier.

What about ScaleChem?

Yes, we are still supporting ScaleChem although it is largely replaced by OLI Studio ScaleChem.  We refer to the classical ScaleChem program as “ScaleChem Standard“.  The current version of ScaleChem Standard is 9.1.3 but we will release a version 9.1.5 sometime next week.  There were no interface changes to ScaleChem Standard but it will use the new engine and databanks.

Some users (primarily oil companies) have requested that ScaleChem Standard 4.1.11 be made available. C’mon, we have to draw the support line somewhere and it is not supported any longer. We have pulled it from our download page.  If you need a copy I will make it available via our temporary upload/download area. Just ask.

What about the other alliance partner software?

We are still supporting Schneider-Electric’s ProII as well as PSE’s gProm and Andritz’ IDEAS. We have not created new builds for them as of yet.  We can test ProII here at OLI so that will be an easy release. That should occur next week.  The others we cannot test, we have to let the partners test them.  The builds will also be created next week and given to PSE and Andritz.

That’s it…

That’s it for this week. Remember, the OLI Simulation conference is in October. If you are interested in attending check out the OLI Conference Page.

All the best,

Jim Berthold





Welcome Back! August 4, 2014

Welcome Back!

Wow, it’s been almost four years since our last post.  We last posted in 2010.  during that time we shifted our focus to providing a more traditional web site for technical support.  That had been a very time consuming job and now we are back to a more blog focused means of getting the word out.

Lot’s of things have occurred since we last posted. I will highlight just a few.

We’ve moved.

For 23 years OLI Systems was located in Morris Plains, New Jersey. We moved in April 1990 and out in March 2013.  We simply out grew the space.  We are now located in Cedar Knolls, New Jersey which is about 3 miles east of our former location.  We now have some space to grow but already we are nearing capacity.

Staff changes

There have been some changes to staffing since our last post.  First and foremost, Marshall Rafal, founder of OLI, has semi-retired.  After a 40 year plus career Marshall has decided to take a lesser role in the day-to-day activities in the company.  Marshall has left Andre Anderko as the Managing Director of the company.

Robert Young is also semi-retired.  After many years at OLI Systems Bob has reduced his work week to 2 days.

Adrian Ferramosca has left OLI Systems and has become a contractor to OLI.  We wish Adrian well in his endeavors.

Honggang Zhao has left OLI for Shell Oil in Houston. He continues his modeling work in sub-surface fluid flow.

We have added to our staff

  • Ali Eslamimanesh – Data developer
  • Prodip Kundu – Software developer
  • Jianping Liu – Data developer
  • Zoushu Lu – Software developer
  • Rasika Nimkar – Software Support Engineer

You can see all profiles on the OLI Staff page

Current Software

Here is the meat of the blog.  There have been may upgrades to the software including a few product name changes.   Perhaps the biggest change is that we have converted the ScaleChem program into an OLI Studio program. We now call this program the OLI Studio ScaleChem program and have re-branded the older program as ScaleChem Standard. We have also tried to use the same numerical engine for each product.  So the version number now corresponds to the “Engine”.  This also helps with our alliance products:

Here is a list of the current products and the version number.

OLI Studio (including Stream Analyzer, Corrosion Analyzer and Studio ScaleChem)  – 9.1.4

OLI ESP Original – 9.1.3

ScaleChem Standard – 9.1.3

OLI Engine in Aspen Plus (all versions) – 9.1.3

OLI Engine in Aspen HYSYS (all versions) – 9.1.3

OLI Engine in Unisim Design R430 and R410 – 9.0.14

Release cycle

You may have noticed that OLI Studio was updated to version 9.1.4 but most of the other programs are still on version 9.1.3 or lower. We were in the process of releasing the software when we found a problem in the build.  Actually there were two problems which stopped the release cycle.

OLI Studio ScaleChem

We updated some of the reports and found that the report in the “Saturator” object was not properly created for this version.  A new section was added which worked for old cases but not new cases.  Testing new features is often difficult.

Chemistry Model Generation

This affects all programs. We have had a species in the GEOCHEM (and GEMSE) database for many years.  This species is CHAMOSITE which has the following equilibrium equation (ESP notation – sorry):


This is the longest chemical equilibrium in the OLI software. The equation was valid in all versions 9.0 and earlier but it crashes out the chemistry model generator in version 9.1 and later.  We traced it down to a FORTRAN compiler optimization method which has failed.  Why it has failed is still to be determined.

Until we figure this out we have halted the release cycle.

Informing the user community

Once the aforementioned bugs are corrected we will begin the release cycle again. The next version is scheduled to be version 9.1.5 for all products. Once it is built and tested we will inform the entire OLI user community of the release.  This will be a mass-email which will take several days.  We only notify about 250 users per day to avoid our Email system tripping anti-SPAM programs.

Announcing the 26th OLI Simulation Conference

Well it’s that time again. We are holding our 26th (or is it the 27th?) OLI Simulation Conference October 21 and 22, 2014 in Florham Park, New Jersey. Click the link for more details.

Well that’s it for now. Until next time (hopefully sooner than four years),

Jim Berthold

OLI Updates for October 2010

Announcing new Releases

OLI  has been busy this fall. We have our 25th OLI Simulation Conference coming up in November and we have just released updates to the OLI Analyzer and to ESP.

OLI Analyzers and ESP have been released.

We released ESP 8.2.4 in August this year and it was a stable version. Unfortunately this was not true for the Analyzers. We released version 3.1.4 at the same time but had all kinds of issues with the mix calculation. This prompted a quick release of a new version 3.1.5 to address the mix calculation issues. This emergency release did not include any database updates.

We are announcing the release of 8.2.6  of ESP and 3.1.6 of the Analyzers. Please note that there was no official release of ESP 8.2.5. Here are some of the updates for each product:


  1. Updated Database
  2. The API method for calculating thermal conductivity and surface tension has been added for pseudocomponenets.
  3. Speed improvements for the computaion of pseudocomponents has been implemented.
  4. Ion-exchange documentation has been improved
  5. The code base for the alliance engines has been made unified.
  6. 2nd liquid case initialization has been improved for multiple point surveys.
  7. Copper Chemistry has been added to the corrosion rate model
  8. See the full set of release notes for ESP


  1. Updated Database
  2. All of the solver updates for ESP were included
  3. General improvements to the Mix Calculations
  4. See the full set of release notes for the Analyzers

OLI Updates for July 2010

Happy 4th of July

OLI took some time off for the 4th of July holiday here in the United States. After barbecues, parades and fireworks we are back to work.

Announcing some new releases.

OLI has recently upgraded the solvers and the interfaces to include some new features.  As an overview we have added Standard Liquid Volume, thermal conductivity and surface tension calculations to the code.  The surface tension and thermal conductivity  is based on work done by Peiming Wang of OLI.  The standard liquid volume was created by Bob Young of OLI.  Both ESP and the Analyzers have been updated with this code.

A long standing problem of phase inclusion when sublimation has been included has been fixed.  This pesky bug resulted in different answers for phase behavior depending on the starting condition of a calculation.  This was dramatically apparent in temperature surveys.  Previously if you started a temperature survey at 25 C you obtained different answers than if you started at 50 C.  This has been resolved.

We plan on releasing both ESP and the Analyzers sometime in July.  There will be an interim announcement when that occurs.  Work continues on updating the alliance products for Unisim Design, ProII and IDEAS. These updates should be ready by August.

All the best,

Jim Berthold
