Using Hydrocor Light

The Hydrocor Light version is a simplified version of Hydrocor. It predicts the Unmitigated Corrosion Rate, for a single point, in a carbon steel pipeline or similar Equipment, at a water full system, based on the latest CO₂, Organic Acid, and Sour corrosion models. No flow model is included in Hydrocor Light.

Note: IF you do not have a license for Hydrocor you will by default have access to Hydrocor Light.

Starting a Hydrocor Light Assessment

To start a Hydrocor Light assessment:

• Find you Equipment
• Click the Internal Corrosion button to open the Internal Corrosion Details Page.
• Go to the Hydrocor section.
  Go to your Equipment's Internal Corrosion Page and then to the Hydrocor section.

   

•  Click the Plus button to start a new Assessment.
  Click the Plus button.
• Add a Date, a Name, and Description. You can also create a Copy from a previous Case.
• Click Save. 

Entering the Data

The input section allows you to enter the process conditions at a specific point, for which you want to evaluate the corrosivity.

Take Note

The Measuring Units can be either metric to imperial. This is selected in the IMS header menu:

Measurement Units setting. 

To enter the process conditions at a specific point:

• Click the Edit button.

• Enter values for
  • CO₂ content of the gas.
  • H₂S content of the gas.
  • Temperature.
  • Pressure.
  • Total acetic acid + acetates in water.
  • Total alkalinity (expressed as Bicarbonate).
  • Chlorides.
  • Velocity.

Note: Default values will already be entered.

• By default Scale protection is checked and IMS will take credit for FeCO₃ protection. If you do not want to take credit for Scale protection uncheck this option.

By default IMS takes credit for Scale protection. 

• Click the Save button.

When you have entered the process conditions, click the Save button.

• Click the Hydrocor button to run the calculation. 

Click the Hydrocor button to run the calculation. 

After you clicked the Hydrocor button, the results will be calculated.

The output includes:

• The Unmitigated Corrosion Rate.
• The in-situ pH.

The calculated output. 

Assumptions

Take note that the predicted Unmitigated Corrosion Rate is:

• For a single point.
• In a carbon steel pipeline, or similar Equipment.
• At a water full system, and
• Is only based on the latest corrosion models for:
  • CO2,
  • Organic Acid, and
  • Sour corrosion.
