Argon purification and recycling system for optical emission spectroscopy

Overview

The proposed solution is an innovative argon purification and recycling system tailored for use in Optical Emission Spectroscopy (OES) within the steel industry. It addresses the challenge of utilizing industrial pipeline argon by effectively removing contaminants such as dust, oil mist, hydrocarbons, nitrogen, and moisture. The system integrates high-efficiency filtration, adsorption-based purification, and advanced recovery techniques to provide a cost-effective, sustainable solution that minimizes gas wastage and operational costs while maintaining the high purity standards required for accurate steel analysis.

Technical specifications

Key Features:

• Filtration and Adsorption: Utilizes a combination of pre-filters, coalescing filters, sub-micron particle filters, and various adsorbents like molecular sieves, activated alumina, and activated carbon to remove impurities.
• Purification Systems: Employs cryogenic, getter-based, and catalytic purifiers to eliminate residual contaminants.
• Argon Recovery: Integrates membrane separation, pressure swing adsorption (PSA), and cryogenic distillation for effective argon recovery and recycling.
• Real-Time Monitoring: Continuous monitoring systems ensure impurity levels remain below 1000 ppm for high purity standards.

Technology readiness level

This technology is currently at TRL 2, indicating that it is in the early stages of development with fundamental concepts formulated and validation of the core components planned for future testing. Further validation and optimization will focus on system integration, performance testing, and ensuring sustainability and cost-effectiveness in operational environments.
