The carbon fiber manufacturing industry requires a unique process control solution that conventional gas detection technology lacks. Boreal Laser’s line-of-sight laser based gas detection system is the perfect fit for measuring HF in various pan oven applications and stack emissions monitoring . Whether you are looking for gas detection solutions for safety, environmental or process control needs Boreal Laser has you covered.
Boreal’s TDL technology has several benefits for Carbon Fibre Manufacturing:
- Provides continuous and instantaneous response times and data collection.
- Very reliably delivers accurate readings.
- No interference with other gases and No False Alarms: “It finds exactly what you’re looking for.”
- Ease of data collection and interpretation.
- Minimal Maintenance: checks internal reference cell every minute, robust design, and requires no consumables to operate.
- Low (overall or amortized) cost of ownership (because they can last +20 years) and low operation and maintenance costs.
- Our technology is as close to set, collect, and forget as possible.
Carbon Fibre Gas Detection Applications:
In-situ Pan Oven Gas Detection
Localized heating caused by tow lines coming to contact with each other can create elevated levels of HCN and NH3 in the pan oven. It is possible for the level of HCN to reach explosive limits in which can cause server damage to the facility and could be fatal to operational personnel. Boreal’s open-path HCN and NH3 measurement technology is the best possible measurement technique to provide the appropriate process and safety measurement inputs to ensure the pan over is in a safe operational state.
During normal operation the slates in the vestibules draw in air but if the oven becomes out of balance then positive pressure can occur then HCN and NH3 produced in the process can come through the slates and into ambient atmosphere. Our technology can be used to monitor the process to ensure that the ovens draft is in balance and operating as efficiently as possible.
Fugitive Emissions Monitoring Produced from Pan Ovens
From a safety monitoring perspective it is preferable to monitor HCN release events as quickly as possible. The best way to do this is to measure across the faces of the oxidation ovens. Paths across the outside tops of the ovens outside the vestibules give a real time indication of HCN levels outside the ovens. Since the laser transceiver heads and reflector are offset from the faces of the ovens, they don’t get fouled by the VOC laden smoke that can come out of ovens and foul other gas detection methodology. The laser will detect the presence of HCN laden gas at any point along the path; not just at one location. Two conditions that can cause a potentially dangerous spike in HCN levels outside of an oven. The first is a fan failure to the exhaust header. This can cause a significant spike in gas levels. In this scenario, HCN escapes out both sides of an oven and can reach levels of up to 50 ppm. The second scenario is when an oven is operating out of balance. In this case, internal gasses can bleed out of side of the oven that’s lower pressure.
Depending on the location of your facility, there may be emissions based targets in which the local regulatory agencies will enforce to approve operating licenses. Boreal provides the HCN and NH3 stack emissions monitoring solution required to ensure your Carbon Fiber Manufacturing facility is within its permissible limits.
