Objective:

In this article, we will introduce the OLI Studio: Stream Analyzer user interface, review the types of calculations that can be performed, execute a series of basic calculations to understand the software’s capabilities, and explore the Report and Plot outputs.

Disclaimer: The user interface, calculations, and results displayed in this article are from OLI Studio Version 12.0.0. Other software versions may appear different or present slightly distinct results due to continual developments to the software and thermodynamic databanks.

Intro to the User Interface

The video below introduces the OLI Studio: Stream Analyzer user interface.

Overview of Possible Calculations

Optional Calculation Outputs

To enable optional outputs, select the Global Stream selected in the Navigator Panel, navigate to the Menu Bar > Tools > Options… > Calculation Options tab. Optional outputs include:

• Diffusivities, Electrical Conductivity, Heat Capacity, Activities, Fugacities, K-Values, Gibbs Free Energy, Entropy, Thermal Conductivity, Surface Tension, Interfacial Tension, Total Dissolved Solids, Scaling Induction Time(s), Pre-scaling Tendencies

The user can enable these properties in the Specs… window of an individual calculation.

To view these outputs after running a calculation, navigate to the “Output” tab > right-click anywhere on the gray space > select “Sections.”

Water Analysis Conversions

Brine analysis data obtained from Inductively Coupled Plasma (ICP) measurements will often include concentrations for elements such as Boron (B), Phosphorus (P), Sulfur (S), and Silicon (Si). These elements do not exist in water as pure elements; instead, they exist as dissolved ions. If these elements are part of your analysis, you must convert them to their corresponding aqueous species before entering them into the Water Analysis object.

Here’s how to convert the concentrations of these elements to their respective aqueous species:

Boron (B)

• Aqueous Species: Boric Acid
• Formula to Enter: H3BO3
• Conversion: B (mg/L) × 5.72 = H3BO3 (mg/L)

Silicon (Si)

• Aqueous Species: Silica
• Formula to Enter: SiO2
• Conversion: Si (mg/L) × 2.14 = SiO2 (mg/L)

Phosphorus (P)

• Aqueous Species: Dihydrogen Phosphate
• Formula to Enter: H2PO4-1
• Conversion: P (mg/L) × 3.13 = H2PO4 (mg/L)

Sulfur (S)

• Aqueous Species: Sulfide or Sulfate (depending on the form)
• Formulas to Enter: HS-1 or SO4-2
• Conversion:
  • For Sulfide: S (mg/L) × 1.03 = HS-1 (mg/L)
  • For Sulfate: S (mg/L) × 3.0 = SO4-2 (mg/L)

Example Conversion

If your ICP measurement indicates:

• Boron: 10 mg/L
• Silicon: 15 mg/L
• Phosphorus: 8 mg/L
• Sulfur: 12 mg/L

You would convert these concentrations as follows:

• Boron: 10 mg/L × 5.72 = 57.2 mg/L of H3BO3
• Silicon: 15 mg/L × 2.14 = 32.1 mg/L of SiO2
• Phosphorus: 8 mg/L × 3.13 = 25.04 mg/L of H2PO4-1
• Sulfur:
  • For Sulfide: 12 mg/L × 1.03 = 12.36 mg/L of HS-1
  • For Sulfate: 12 mg/L × 3.0 = 36 mg/L of SO4-2
