UOP 938 Carbon Dioxide Content in Produced Water Test

The UOP 938 method is a widely recognized procedure used to determine the carbon dioxide (CO₂) content in produced water from oil and gas operations. This test is crucial for environmental compliance, process optimization, and safety management in the oil & gas sector.

The produced water generated during oil extraction contains various dissolved gases including CO₂. Accurate measurement of CO₂ content helps operators understand the composition of the water stream, which is critical for downstream processing, waste disposal, and environmental impact assessment. This test ensures that the water meets regulatory standards set by agencies such as the Environmental Protection Agency (EPA) in the U.S.

The procedure involves several steps: sampling, sample preparation, gas extraction, and analysis using a gas chromatograph equipped with an electron capture detector (GC/ECD). The method is described in detail in ISO standards. It provides precise quantification of CO₂, which aids in making informed decisions regarding water management.

Sampling produced water for this test requires careful handling to avoid contamination and ensure accurate results. Proper sample preparation is critical, involving the use of degassing techniques to remove volatile components before analysis. The gas chromatograph used for CO₂ quantification is calibrated using certified reference materials to ensure accuracy.

The UOP 938 method is robust and reliable, offering consistent results across different samples. Compliance with this standard ensures that the data generated can be trusted and accepted by regulatory bodies. The test also helps in identifying potential issues such as CO₂ overloading, which could lead to scaling or corrosion in processing equipment.

In summary, the UOP 938 method is an essential tool for monitoring CO₂ content in produced water. It supports environmental stewardship and operational efficiency by providing accurate data needed for regulatory compliance and process optimization.

Sampling: Proper collection of representative samples from the production site.
Safety: Use of appropriate personal protective equipment during sampling and analysis.
