 Unique features of CO2Compass not found in any other commercially available CO2 modeling software

1. Performance Guarantee

If at any time during the licensed period, the corrosion rates predicted by CO2Compass are not closer to the measured values than the values predicted by any other CO2 corrosion modeling software on the market, we will refund the pro-rated licensing fee to you. It is that simple. No other CO2 corrosion modeling software developer offers you this performance guarantee. CO2Compass models the effects of liquid velocity, dissolved oxygen, bicarbonate, NaCl, H2S, elemental sulfur and HAc on CO2 corrosion rates more realistically than any other CO2 corrosion modeling software. Do not take our word for it - show us proof of your current ownership of any commercial CO2 corrosion modeling software and we will give you a license for the full version of CO2Compass completely free for up to 3 months. Validate your existing CO2 corrosion modeling software and CO2Compass using the recommended CO2 corrosion model validation matrix and see for yourself the striking performance difference.

 

2. Unparalleled Functionality

Practical Solutions: CO2Compass is not just for CO2 corrosion rate prediction. It also provides  users with expert guidance on practical solutions for mitigating CO2 corrosion. Based on the predicted corrosion rate, the prevailing operating conditions, the flow regimes, and the water analysis results, CO2Compass makes an overall assessment of the complete system and generates recommendations for CO2 corrosion mitigation strategies:

(1) Corrosion and Inhibitor Risk Categories and Guidelines with Corrosion
      Dominating Process and Inhibitor Likelihood Success Score (ILSS)
(2) SSC and HIC Susceptibility (NACE MR 175/ISO-15156: 2015)
(3) Corrosion Control Options (CO2 Removal; Glycol Injection; pH  
      Stabilization; Water Removal)
(4) Material Selection Options (Carbon Steels, 316 SS, Duplex SS & CRAs)

 

Under the Corrosion Control Options, the critical levels of four major parameters (CO2 content, glycol concentration and injection rate, pH and bicarbonate dosage, and water content) that can independently reduce the predicted corrosion rate to meet the design value  are all calculated automatically. CO2Compass gives the user effective and powerful tools to assess and optimize a particular CO2 corrosion mitigation strategy. For example, CO2 removal can be used alone or in combination with other options such as corrosion inhibition, glycol injection, and pH stabilization to reduce the predicted corrosion rate to a level that meets the design requirement, thus extending the applicability of carbon steels to situations that might otherwise require the use of CRAs. This unique feature alone can literally save asset owners millions of dollars. A real-life case study is presented in the 5-day course on "CO2 Corrosion Modeling for the Prediction of Internal Corrosion in Oil & Gas Pipelines".

 

Scale Prediction:

CO2Compass has a built-in module for the prediction of scaling tendency. The seamless integration of the scale prediction engine into the rigorous thermodynamic framework for corrosion modeling makes CO2Compass a powerful tool in assessing and mitigating the risks of both corrosion and scaling at the same time and with minimal effort from the user. Saturation indices for scales commonly encountered in oil and gas production, processing and transmission are calculated automatically based on the prevailing operating conditions and water analysis results.

 

 

 

In-situ pH Calculator:

An in-situ pH calculator allows the user to instantly determine the in-situ pH under the prevailing operating conditions (high temperature and pressure) from the water analysis conducted in the laboratory at ambient temperature and pressure. If the target in-situ pH for pH stabilization treatment is changed, the required concentration of [HCO3-] to meet the target in-situ pH is instantly calculated. The scaling tendency under pH stabilization treatment is updated dynamically in real-time, allowing the user to assess and mitigate the risks of both corrosion and scaling at the same time and with minimal effort.

 

 

3. Unmatched Usability: CO2Compass was designed with the user in mind. Experience the industry's first cross-platform and device-independent CO2 corrosion modeling and prediction application on your iPads, tablets, smart phones, notebooks and desktops, at any time and anywhere, in the office or in the field. No installation files to download, no browser plug-ins required, no USB dongles to carry around, and no license keys to transfer from one PC to another. CO2Compass simply works on any device running any OS. All you need is an internet browser. Try the demo version on all your mobile devices and desktop computers and see for yourself the power of CO2Compass. Calculations in CO2Compass are performed on the server, with real-time display of results and charts. Unlike the black-box style of other CO2 corrosion modeling software, CO2Compass gives the user complete and direct control over the modeling of the effects of scaling, oil wetting, glycol, CO2 fugacity, in-situ pH, liquid velocity, organic acids, and H2S with user-controlled ON/OFF switches and direct inputs overriding the default settings. Automatically generated and dynamically updated graphs are plotted in real-time as the user makes adjustments to the input parameters. These plots include corrosion rate profile, effect of temperature, effect of velocity, and effect of pH on the predicted CO2 corrosion rates. Saturation indices of carbonates and sulphate scales are also plotted. A clean and concise report is automatically generated and dynamically updated in real-time as you enter or change the input parameters.

 

A Brief Overview of CO2Compass

 

 

CO2Compass has a clean and efficient user interface that instantly responds to changes in user inputs. You do not need to select the input parameter range before entering the input parameter value or wait for flashy and sluggish screens to update the displayed calculation results. In CO2Compass, all input parameters are presented under the Inputs Tab. All calculation results are presented under the Outputs Tab. Users have complete control over the modeling process by directly overriding the default settings for parameters such as in-situ pH, liquid velocity, FeCO3/Fe3O4 scale protection, FeS scale protection, oil wetting, glycol effect and CO2 fugacity. Refer to the image below for details.

 

 

Unique features in CO2Compass not found in any other commercial CO2 modeling software include:

 

The Corrosion Risk Category, the Corrosion Dominating Process, the Inhibitor Effectiveness, measured by the Inhibitor Likelihood Success Score (ILSS), the Inhibitor Risk Category and typical inhibitor dosage are automatically generated as outputs.

 

Under the "Corrosion Control Options", the critical levels of pCO2, glycol, pH and H2O that can reduce the corrosion rate independently to meet the design requirement are calculated automatically based on the prevailing conditions. Users have the option to use the ON/OFF switches and adjust the input parameters to optimize a particular CO2 corrosion mitigation strategy. For example, glycol injection and pH stabilization can be optimized to permit the use of carbon steels in situations where CRAs may have to be considered. Refer to the image above for details. In this particular case shown in the image above, the predicted CO2 corrosion rate with corrosion inhibitor at 90% efficiency and 95% availability is 0.18 mm/y, which is still above the design limit of 0.1 mm/y. CO2Compass makes an overall assessment of the situation and automatically generates options available to the user: (1) CO2 removal alone can be used to reduce the inhibited CO2 corrosion rate to the design limit. The maximum CO2 partial pressure allowed is 0.400 bar or the maximum concentration of CO2 allowed is 0.800%. Note that reducing the total system pressure will also lower the partial pressure of CO2; (2) glycol injection alone can be used to reduce the inhibited CO2 corrosion rate to the design limit. The minimum concentration of glycol required is 31.83% or the minimum injection rate is 491 kg per MMSM3 gas; (3) pH stabilization alone can be used to reduce the inhibited CO2 corrosion rate to the design limit. The minimum pH required is 5.65 and the minimum concentration of bicarbonate to achieve the required pH is 340 ppm; (4) water removal alone can also be used to reduce the inhibited CO2 corrosion rate to the design limit. The maximum water content in both the gas phase and the liquid phase should not exceed 99 kg/MMSM3; each of the 4 options can independently reduce the inhibited corrosion rate to the design limit; (5) under the Material Selection Options, CO2Compass calculated the corrosion allowance (CA) required for carbon steel (5.54 mm) if none of the 4 corrosion control options is used. By varying the input parameters, users can optimize a particular CO2 corrosion control strategy with combined use of available options, thus extending the applicability of carbon steels to situations that might otherwise require the use of CRAs. This unique feature alone can literally save asset owners millions of dollars. A real-life case study is presented in the 5-day course on "CO2 Corrosion Modeling for the Prediction of Internal Corrosion in Oil & Gas Pipelines".

 

Automatically generated and dynamically updated graphs are plotted in real-time as the user makes adjustments to the input parameters. These plots include corrosion rate profile, effect of temperature, effect of velocity, and effect of pH on the predicted CO2 corrosion rates.
