Analyzers for Cryogenic Air Separation Quality

Product catalog summary
Overview
This document discusses the importance of monitoring gas quality and purity in cryogenic air separation plants. It highlights the need for high-precision analyzers and gas chromatographs to ensure the purity of oxygen (O2), nitrogen (N2), and argon (Ar) produced through cryogenic air separation. The document emphasizes the detection of impurities down to parts per trillion to maintain ultra-high purity levels.

Cryogenic Air Separation Process
The process involves several stages: air feed filtration, compression, liquid water removal, molecular sieve for H2O, CO2, and hydrocarbon removal, booster compression, turbo expansion, heat exchange, cryogenic distillation, and storage of liquid argon, nitrogen, and oxygen.

Product Selector and Benefits
The document outlines the benefits of using reliable analyzers for trace impurities, offering a complete measurement solution from a single supplier. Key measurement parameters include trace moisture, trace oxygen, trace gases, and trace hydrocarbons.

Applications and Measurement Purposes
Various applications are listed, such as measuring O2 product purity, monitoring oxygen and moisture content during gas cylinder certification, and ensuring the quality of gases transported via pipelines. The document provides specific analyzer options for each application.

Analyzer Options
Several analyzers are detailed, including:
  • LDetek MultiDetek3 for modular process gas chromatography.
  • LDetek LD8000 for online PPB trace nitrogen analysis.
  • LDetek LD2000 for trace total hydrocarbons analysis.
  • Michell XTC601 for binary gas analysis.
  • Analytical Industries Inc PI2-MS for ultra-high purity gases.
  • Michell Instruments XZR400 and XTP601 for oxygen analysis.


Trace Moisture Measurement
Products like Michell Pura, Easidew, and QMA401 are highlighted for measuring trace moisture content in gases, offering precision and low maintenance.

Ambient Monitoring
The Ntron Gasenz ambient oxygen analyzer is featured for monitoring oxygen levels in work areas to prevent asphyxiation or explosion risks.

Conclusion
The document concludes by emphasizing the importance of using specialized analyzers to monitor and ensure the quality of gases in cryogenic air separation processes, highlighting the expertise and product offerings of DwyerOmega and ProcessSensing.
