Oxygen Measurement in Petrochemical Feedstocks & Pure Gases
Trace O2 Quality Control for Monomer Feedstocks & Ultra-High-Purity Gas Supply — OMD-625
Petrochemical feedstocks such as ethylene and propylene, along with high-purity gases used for purging and polymerization processes, often require stringent oxygen specifications. Trace oxygen contamination can poison sensitive catalysts, affect polymer quality, or create hazardous conditions where pyrophoric materials are present.
The Southland Sensing OMD-625 trace oxygen analyzer provides continuous oxygen monitoring of compatible petrochemical feedstocks and purge gas supplies, helping producers verify oxygen concentrations before these gases reach sensitive process equipment.
- UHP Gas Purity
- Feedstock Quality Control
- Catalyst Protection
- Process Reliability
Why Trace Oxygen Quality Control Matters
In polymerization and other catalytic petrochemical processes, even low-ppm levels of oxygen can adversely affect sensitive catalysts, leading to reduced yields, off-specification products, and costly catalyst replacement. Verifying oxygen concentrations in incoming feedstocks and purge gas supplies before they reach the reactor helps protect product quality, catalyst performance, and process reliability.
Where It's Used
- Feedstock gas receipt QC — verifying incoming ethylene/propylene purity
- Polymer-grade monomer verification — confirming feed meets catalyst tolerance limits
- Purge gas quality checks — validating nitrogen or other inert purge supply
- UHP gas supply monitoring — ongoing verification of ultra-high-purity gas systems

Häufig gestellte Fragen
Trace oxygen contamination can negatively affect oxygen-sensitive catalysts used in polymerization and other petrochemical processes. Monitoring oxygen concentrations in ethylene, propylene, and other compatible feedstocks helps protect catalyst performance, maintain product quality, and reduce costly process interruptions.
Acceptable oxygen concentrations depend on the specific feedstock, catalyst, and process requirements. Some applications require oxygen concentrations in the low-ppm range or below. Continuous trace oxygen monitoring helps operators verify compliance with established process specifications.
Yes. The Southland Sensing OMD-625 provides continuous trace oxygen measurements at designated sampling points on compatible feedstock and high-purity gas supply lines. Proper sensor selection and sample conditioning depend on the gas composition, pressure, and operating conditions.
