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.

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.

Reviewing the Results
After you clicked the Hydrocor button, the results will be calculated.
The output includes:
- The Unmitigated Corrosion Rate.
- The in-situ pH.

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.
