# Using Hydrocor Light

## 

Take NoteThis manual will explain how to use Hydrocor Light inside PLSS. 

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](/v414/docs/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.![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/pic%201(782).png?sv=2026-02-06&spr=https&st=2026-10-28T19%3A57%3A47Z&se=2026-10-28T20%3A57%3A47Z&sr=c&sp=r&sig=eWFa9eembAFzqBRGUdcqtH%2BQ9FCD%2BCiECN2gaFb8R90%3D)Go to your Equipment's Internal Corrosion Page and then to the Hydrocor section.
- Click the *Plus* button to start a new Assessment.![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/pic%201(783).png?sv=2026-02-06&spr=https&st=2026-10-28T19%3A57%3A47Z&se=2026-10-28T20%3A57%3A47Z&sr=c&sp=r&sig=eWFa9eembAFzqBRGUdcqtH%2BQ9FCD%2BCiECN2gaFb8R90%3D)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 NoteThe Measuring Units can be either metric to imperial. This is selected in the IMS header menu:

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.

## Creating additional Cases

To start an addition Assessment Case:

- Click the *Plus* button again.
