Oxygen Monitoring and Process Safety for Solvent-Based Adhesive and Sealant Production

In the manufacturing sector, safety and quality go hand in hand, especially in processes involving flammable materials like solvent-based adhesives and sealants. Effective oxygen detection and nitrogen blanketing are critical components in this application, as they play an essential role in preventing hazardous conditions while maintaining product integrity.

For a fire to ignite, three elements must be present:

  • 1. Fuel - In this, the solvent used in the production process.
  • 2. Oxygen - To support the combustion of fuel.
  • 3. Ignition Source - Such as a spark or heated surface.

Eliminating one of these elements can mitigate the risk of fire. Tank blanketing, which involves replacing oxygen with an inert gas like nitrogen, is an effective method for removing oxygen from the process.

Importance of Oxygen Detection

Enhanced Safety

By maintaining oxygen levels below the limiting oxygen concentration (LOC), the risk of fire and explosion is significantly reduced. This not only protects the facility and its workers but also ensures compliance with safety regulations.

Improved Product Consistency

Correct oxygen levels ensure that each batch of adhesive or sealant meets quality standards. This consistency and product quality is crucial for building customer trust and maintaining a good reputation in the market.

Cost Savings

Preventing fires and explosions saves companies significant amounts in lost production, site safety reviews and potential rebuild / repair costs. Additionally, producing consistent, high-quality products reduces waste and rework, further contributing to cost savings and customer satisfaction.

Best Practices for Implementing Oxygen Detection Systems

Correct Instrumentation for you application

Selecting the right measurement technology and associated instrumentation is vital for safe and reliable operation and to adhere with appropriate regulations. Several measurement technologies and instrumentation types exist, good suppliers and manufacturers can consult on your application and compliance needs to provide the best solution and support for your project.

Regular Maintenance and Calibration

Regular maintenance and calibration of oxygen analyzers is critical to ensuring ongoing accuracy and reliability in monitoring oxygen levels. Over time, some sensors can drift from their calibrated values due to environmental factors, contamination, or prolonged use. Calibration or verification is often a quality or regulatory requirement that must be undertaken. Consequently, periodic verification against known standards is essential to maintain precise readings and to ensure that the oxygen detection system operates effectively.

Conclusion

Accurate oxygen monitoring is crucial in identifying or controlling potential hazards before they escalate, thereby safeguarding both personnel and equipment. Regularly scheduled maintenance and calibration ultimately contribute to the longevity of the analyzers, reducing the risk of unexpected failures that could lead to costly downtimes or safety incidents. By investing in these practices, manufacturers can enhance overall process safety and maintain high-quality product standards.
