Carbon Fiber Emission Control Technologies

Programable Logic Controlers (PLCs): automate operation to shutdown, minimizing operator interface requirements. Remote telemetry enables the system\'s operation to be viewed and altered via modem, reducing maintenance costs and downtime. Control rooms and various enclosure options are available.

The main system fan is oversized to minimize the impacts of silica dust plugging.

Heat Recovery Beds are designed in a multi-layer configuration to prevent silica dust from collecting and clogging in the oxidizer.  Should build-up occur, the RTO media accomodates periodic cleaning and potential replacement, if required. 

Poppet Valves: Zero leakage, dual-disk Poppet valve design achieves 99%+ destruction efficiency without a puff chamber or reliability concerns.

Low NOX burner designed to maintain temperature during full flow, no VOC process conditions.

Gas trains are designed to meet FM Global or any international certifications such as CSA, EN, TSSA and CGA.

99%+ Destruction Rate Efficiency (DRE), Regulatory Compliance Guaranteed.

Hinged Access Doors: allow for easy maintenance and quick inspection of the valves.

Hinged Access Doors: oversized access ports are designed to facilitate media removal for cleaning of silica dust in a timely manner.

Gas trains are designed to meet FM Global or any international certifications such as CSA, EN, TSSA and CGA.

99%+ Destruction Rate Efficiency (DRE), Regulatory Compliance Guaranteed.

Properly sized reactor chamber provides high destruction efficiency.

Reduction, Cooling & Oxidation Zones treat emissions under various temperatures and oxygen depleted conditions to ensure complete destruction with minimal NOx generation.

Reactor has ceramic lining, high density insulation and painted steel weatherproof enclosure that allow for the processing of highly concentrated streams.

A modulating burner and digital controller maintain proper air temperature.

Independent process and combustion air blowers ensure a safe, long-term operation with proper oxygen content.

Anguil is the leading supplier of abatement systems used for the destruction of Hydrogen Cyanide (HCN), Ammonia (NH3), Silicone and Nitrous Oxide (NOX) emissions that are often produced in the ovens and furnaces of carbon fiber - sometimes spelled fibre - plants.  

Carbon fiber and graphite reinforced polymers are materials that have, and will continue to revolutionize the products we use every day by making them stronger, lighter and more durable.  However, the manufacturing process can have serious environmental ramifications and immediate danger to human health if careful consideration is not given to emission control at the production phase of these materials. 

We design, manufacture, service and install energy-efficient oxidizer systems designed specifically for the air toxins that are often produced in the ovens and furnaces of carbon fiber manufacturers.  Our energy-efficient, abatement technologies have been successfully applied at some of the most technologically advanced facilities in the industry.  For example, Oak Ridge National Laboratory (ORNL) and The University of Nottingham utilize different, yet highly effective air pollution abatement technologies that also drive down production costs.     

As is the case with many industrial manufacturing operations, emissions are best destroyed through the use of thermal oxidation technologies via high temperature combustion.  However, very few industries use custom designed solutions like the carbon fiber processing industry does.  The design considerations for each of these technologies are described in the animations above and text below:

  • For the higher flow, lower concentration oven exhaust Anguil also manufacturers a Regenerative Thermal Oxidizer (RTO).  This type of oxidizer is capable of greater than 99%+ destruction efficiency with very low operating costs.  With achievable thermal efficiencies over 97% the RTO is capable of operating with little to no supplemental fuel use.
  • Low and High Temperature (LT / HT) furnaces on carbon fiber processes generate emissions streams heavily concentrated with pollutants.  This makes it an ideal application for the Direct Fired Thermal Oxidizer (DFTO) where high destruction is required but special design considerations should be taken to reduce operating costs and greenhouse gas emissions. 
  • To account for the by-products of combustion, Anguil has designed a specialized Multi-Stage Direct Fired Thermal Oxidizer (MS-DFTO) whereby the nitrogen compounds are disassociated at high temperatures under oxygen depleted conditions.  The remaining gases move into secondary zones where total emission destruction efficiencies are over 99% with minimal NOX generation.

As every carbon fiber process is different and each site has unique characteristics, much can be learned from past experience.  Anguil is an air pollution control system provider with over 35 years of experience and multiple systems installed in the carbon fiber industry.  Trust Anguil to design the most cost-effective solution for your specific process.
