Ethylene Oxide Measurement

EtO

In December 2016, the U.S. Environmental Protection Agency finalized its evaluation of the inhalation carcinogenicity from long-term inhalation exposure to ethylene oxide (EtO). The results were published via the Agency’s Integrated Risk Information System and indicated an increased carcinogenic potential for exposure to airborne EtO in the vicinity of facilities operating with EtO. This resulted in increased public scrutiny and subsequently led to a need for the industry to better characterize and control EtO emissions and leaks. CleanAir has developed a unique skillset and partnerships that allow it to utilize the best available measurement technology to find solutions for generating defensible data aiding in confident decision making and managing exposure risk.

Continuous Emissions Monitoring System Integration

CleanAir can design and integrate Continuous Emissions Monitoring Systems (CEMS) to continuously monitor EtO concentrations in exhaust flues and process gas streams. Based on the project objectives and monitoring requirements, CleanAir’s system approach can be based on Fourier Transform Infrared Spectroscopy (FTIR), Gas Chromatography (GC), or Broadband Cavity Ring-Down Spectroscopy (BB-CRDS). CleanAir’s system approach includes:

Custom system design to meet any monitoring requirements
Custom sampling system design for areas where gas concentrations can reach combustible levels (Class 1 Division 1 and 2)
Fully automated system operation and calibration
Remote cloud-based monitoring and data management
Monitoring plan generation for assurance of defensible data
System maintenance and data management services

Fenceline Monitoring

Characterizing EtO levels at facility fencelines requires ultra-high sensitivity for permanent ambient monitoring systems paired with rapid responses when aiming to characterize EtO plumes. CleanAir offers solutions for both based on Picarro’s EtO Gas Concentration Analyzer lineup. In addition, CleanAir can help with any ambient and fenceline monitoring project needs by providing planning, execution, reporting, and associated consulting services. CleanAir’s monitoring solutions and services involve:

Custom system design for permanent or portable EtO monitoring
Parts-per-trillion (ppt) level detection limit
Scalable rapid-response multi-point sampling system (up to 256 points)
Fully automated system operation and calibration
Remote cloud-based monitoring and data management
Quality Assurance Project Plan (QAPP) generation for assurance of defensible data
System maintenance and quality assurance, data review, validation and reporting

Indoor Air Quality Monitoring

Using innovative technology based on Picarro’s G2910 EtO Gas Concentration Analyzer, CleanAir has designed a monitoring system that fulfills the primary need for monitoring indoor air quality – the rapid generation of highly accurate and precise data to pinpoint potential leaks of EtO throughout the facility and quickly take actions. The highlights of CleanAir’s system design approach are:

Rapid measurement with parts-per-trillion (ppt) level detection limit
Ultra-high precision measurement for increased decision confidence
Scaleable rapid-response multi-point sampling system (up to 256 points)
Fully automated system operation and calibration
Remote cloud-based monitoring and data management
Uncompromised product support and preventive maintenance services

Leak Detection and Repair (LDAR)

CleanAir offers EtO LDAR services and monitoring system design to rapidly and confidently identify and quantify leaks. CleanAir LDAR approach is based on Picarro’s G2910 EtO Gas Concentration Analyzer that allows the rapid speciation of EtO at ultra-low levels and is characterized by:

Rapid measurement with parts-per-trillion (ppt) level detection limit
Ultra-high precision measurement for increased decision confidence
Portable system design accommodating extended operation without external power
Remote cloud-based monitoring and data management
Unparalleled quality services
