OLI course introduction

Introduction

The OLI Studio

The OLI Studio is freeform electrolyte simulation software. With this software, a client can define

chemistry and process pathways without predefined recipes that produce specific results. The OLI Studio is a software suite containing several modules including, Stream Analyzer, Corrosion Analyzer, and Studio ScaleChem. A client’s license determines which modules are enabled within the OLI Studio.

The Training Manual

This training manual is designed by Aqueous Process Simulations, Inc. (AQSim) to highlight OLI Studio: Stream Analyzer and Corrosion Analyzer features and functions. AQSim has a separate training manual for OLI Studio: ScaleChem.

The manual provides general concepts, theory, explanations of chemical principles, and various

calculations. Certain chapters have follow-up examples, which are designed to reinforce concepts learned within the chapter. The subsequent chapters have real world applications of the software. The manual is self-guided but is also used to accompany trainings provided by AQSim.

OLI Studio Components

Stream Analyzer

Stream Analyzer is standalone software. It requires no additional components to run basic calculations. It is the main interface of the OLI Studio, highlights of which include:

 Thermodynamic Frameworks  Phase Selection and Manipulation  Names Manager and Units Manager  Calculation Objects

 Plotting, Reporting, Customization tools; Water Analysis charge and pH

reconciliation

Corrosion Analyzer

Corrosion Analyzer is a module within the OLI Studio. A separate license enables this module. Highlights include:

 EH-pH Stability (Pourbaix) Diagrams  Species Phase Diagrams

 Polarization Diagrams  General Corrosion Rates  Local Corrosion Rates

 Extreme Value Statistics (a module within Corrosion Analyzer

Studio ScaleChem

ScaleChem was OLI Systems’ standalone, upstream software. This software is now a component within the OLI Studio. Studio

ScaleChem can perform the following operations within both OLI thermodynamic frameworks (Mixed Solvent Electrolytes and Aqueous) and special databases:

 Brine, Hydrocarbon, Oil Analyses  Scaling Scenarios

 Mixer and Saturator Calculations  Facilities

OLI Studio Interface

The OLI Studio modules share a common interface. Clients can hide or show many of the sections described below. For instance, clients can remove the Calculation Status bar or Template Manager or add or remove tools from the Quick Access Ribbon (Toolbar).

The Navigator Pane displays streams and calculation objects in a branched hierarchy. Below this is the Action Pane, which lists all the objects of Studio modules enabled by a client’s OLI license. The Calculation Status and Output bars are on by default but can be hidden. Clients will mostly work in the Description / Definition area, which is contextual - changing depending on which object a client is working on.

Menu Bar

Notable features within the menu bar are explained below. View, Window, Help are options

File

This File menu contains standard options like New, Save, Print, etc.

Properties opens a box that shows file type, location, size, the date, build and version number of the last save.

The most recently worked on streams will also be shown.

Edit

Certain streams can be copied and pasted within the Navigator using the Edit menu or right-mouse click options.

The Edit menu also has the following actions of note:

Clear Results – Removes all

calculation output

Clear Status – Stops or

removes a calculation

Streams

The Streams menu contains actions that can also be performed using the Actions Pane. These actions are Add Stream, Add Analysis, and ScaleChem, which has its own sub-menu.

Calculations

calculation types.

For instance, the Single Point calculation option opens into a submenu for the 10 single point calculations available in the software.

Chemistry

Clients can adjust the chemistry of the software in this menu

Pre-built Models lets clients

create a single, specialized model and port it to or from other application files.

Templates allows clients to

make a series of standard input component sets e.g. a standard seawater

Selecting Model Options opens a submenu with that allows clients to make advanced changes to the chemistry of the software.

Thermodynamic Framework –To select either the Aqueous or MSE

(Mixed Solvent Electrolyte) Framework

Databases – To select an installed database

Redox – To toggle on/off oxidation-reduction reactions

Tools

This menu item contains several features.

Component Search allows clients search for species in the OLI database.

Names Manager

Names Style: clients select how to

view chemical names i.e. by Formula, Display Name or the OLI convention (TAG names).

Search Criteria: clients determine

how the software searches for components. The default option is to search by all available names.

Names Dictionary: clients can

rename components with this tab or import dictionaries used by OLI software.

Toolbar (Quick Access Ribbon)

The Quick Access Ribbon or toolbar sits below the menu bar Menu Bar. Tools within the ribbon can be added or removed or repositioned (the Calculation Status Bar can also be hidden or moved).

To move a set of tools, clients can drag the left side of a set of tools. The ribbon can also be customized by selecting View from the Menu bar, then selecting Toolbars. Key tools are described below:

Phases Turn on/off specific phases i.e. if So (solid) is turned

off, then no solid phases form

Redox Turn on/off Oxidation-Reduction and select redox

subsystems

Chemistry Model Options Select the Aqueous or Mixed

Solvent Electrolyte thermodynamic framework.

Component Search Add inflows to the calculation

Names Manager Changes the style of names i.e. Display, Formula, OLI Tag names Units Manager Changes units

Customize window Customize the window appearance Tools Options Shortcut Adjusts default software settings

Navigation Pane

The Navigator Pane or tree level contains the list of streams and calculations that are active within a file. This view contains the icons and names of each action in a hierarchical tree. The Description/Definition pane changes depending on the level that is highlighted. A plus sign next to an object in the stream level indicates that that stream or object has substreams or branches. There are three main levels here.

Filename A star next to a filename indicates that it has not been saved Global Streams Level Provides the broadest view of Navigator objects Stream Level Chemistry is entered at this level.

Calculation Level Most calculations (except mixing blocks) are

subordinate to streams and appear as substreams. Certain streams (i.e. ScaleChem objects) have embedded calculations.

Calculation sublevel Some calculations have their own substreams.

These substreams can be added to the Global level using the Add as Stream function.

Action Pane

This view contains selectable action icons. Each icon represents either a new stream input or new calculation. Additional actions will appear depending on what kind of stream we are working with.

After adding an item from the action pane, the action appears as a “stream” in the Navigator menu. Depending on the item selected, additional actions may appear in the actions pane. Items can also be selected from the menu bar.

Calculation Types

Once a client selects or highlights an object, object-specific calculations become available in the Actions bar. Stream and Water Analysis objects each have s specific set of calculations. The calculation available within a Water Analysis object is called a Reconciliation. Available Stream calculations are:

Single Point calculations compute the properties for a stream at one set of conditions. Clients choose from isothermal, dew point, bubble point, precipitation point, or custom.

Multiple Point or Survey calculations are a series of single-point calculations in which independent variables such as temperature adjusts with `each calculation (e.g., a temperature survey). Up to two variables can be adjusted simultaneously, and a third can be fixed (e.g., pH or bubble point pressure/temperature). There are several examples of multiple point calculations in the TOT manual.

Chemical or Stability Diagrams, also known as real-solution Pourbaix diagrams, plot the phase stability region across a two-independent-variable range. An example would be Calcite stability when a pH and CO2 vary.

Corrosion Rate calculations compute the general and localized corrosion rates of metals and alloys. They contain both single- and multiple-point calculations

Calculation Status Screens

The Calculation Status Dialog shows an estimate of the remaining calculation time.

The Summary Window shows inputs, calculation outputs, warnings, and has hyperlinks to the Units and Framework managers. This window varies with object.
