Power and Flexibility from Protea’s latest Process and Emission Monitoring Installation
Protea has recently installed and commissioned a powerful process and emissions monitoring system for Blue Star Fibres Ltd, a UK producer of both oxidised and carbon fibre. The system, located at the Company’s Grimsby site, is based on Protea’s flexible model 204 FTIR product customised for the application.
Carbon Fibre is an increasingly important material for the manufacturing industry. From sports goods to vehicle manufacture and wind turbines, the output of carbon fibre is being increased to meet demand.
The fibre is produced from a precursor polymer (Polyacrylonitrile, PAN) that is spun into filaments, which are decomposed in ovens of up to 2000˚C in the process known as carbonisation. The carbonisation process and therefore product characteristics are varied by changing the speed the filament passes through the ovens, the oven temperature, the oxygen content and other process adjustments. During the carbonisation process, off- gases are produced as the PAN fibres are heated. The most critical off gas
is Hydrogen Cyanide (HCN), along with Ammonia (NH3), Formaldehyde (HCHO), Methanol (CH3OH) and other organic compounds in low levels. These off-gas concentrations change as the carbonisation process conditions are changed.
Blue Star Fibres required a system design to measure sequentially up to 8 different emission vents within a fixed monitoring system,
with the additional ability for the FTIR instrument to be demounted and deployed as a mobile unit around various parts of the production when required. For example measurement of acrylonitrile from the PAN production unit is required occasionally. Protea’s system satisfied these requirements fully and exceeded the company’s expectations.
For Blue Star’s fixed emission requirements, Protea supplied a switchable 8-point fully heated sample handling system with the capacity to be expanded in the future. Each sample point consisted of a heated sample probe, heated sample line and heated sample valve all controlled at 180˚C. A separate, detachable heated sample line then connected the main sampling system to Protea’s ProtIR 204M MCERTS-certified Transportable Continuous Emission Monitoring analyser.
The compact design of the ProtIR 204M Transportable CEM gas analyser is particularly well suited to the requirements of carbon fibre plants. When deployed as a CEM unit, it enables vent emission measurements to be continuously taken in compliance with the UK’s Environment Agency requirements. For other applications such as monitoring vents not connected to the system or in remote plants, the 204M can be easily disconnected from the main system and quickly moved as a separate unit to the required measurement point. The 204M remains fully and easily configurable for a wide range of different monitoring tasks.
James England, Carbon Fibre Technical Manager at Blue Star Fibres said; “We were delighted with the solution that Protea provided for us. The installation of such a complex system was efficiently completed and the FTIR system has worked perfectly since commissioning. The ProtIR 204M has already provided us with some extremely useful data and I am more than happy to recommend Protea and Protea solutions to any other potential customers”.

Always Signal at Traffic Lights Since the UK DfT came up with Urban Traffic Management Control (UTMC) as one of its key initiatives to address traffic pollution issues, a major cross boundary project has been undertaken in the West Midlands, UK. Called MATTISSE, it involves Birmingham and Coventry City Councils, Solihull, Walsall, Sandwell and Dudley Metropolitan Borough Councils and is channeled through Wolverhampton City Council for funding purposes.
This project has been designed to reduce congestion in the metropolitan area by bringing together each of the regions’ existing UTC centres into one Centre of Excellence based at Quinton. Managed by Telent, all the individual traffic systems are linked together to collect data and provide information.
An essential part of the MATTISSE system is the network of StreetBox pollution monitors supplied by Signal Group (UK). Continuously monitoring pollutant gases such as SO2, CO and NOx, these monitors provide key data for the analysis of air quality in the region.
The StreetBox has also been used for impact assessment on the construction of new roads, air quality modeling within tunnels and as an indicative measurement of volume of stationary traffic at junctions, which can then be used to alter traffic light signaling timings to reduce stationary waiting traffic down to acceptable levels.

Gas Sampling Equipment meets Industrial Emissions Directive (2010/75/EU)
PRODUCTS AND SERVICES Buhler - Gas coolers,
sample probes & heated hoses Service & spares for JCT, M+C and AGT MAK coolers Filter housings & elements, ADI, KNF, Wisa Gas Sampling Pumps, PTFE / PFA / Viton tubing, seals, gaskets etc.
DRM Technic (UK) has announced the acquisition of the project to upgrade the gas sample conditioning components for a major UK CCGT type gas fired power station, enabling future implementation to IED (2010/75/EU).
The project includes provision to replace the existing “front end” sampling for two stacks at the 800MWe station. The existing equipment, which was coming to the end of its life, was starting to create loss of measurement performance for the analysis systems which is unacceptable to EN14181 and the operators own in-house quality systems.
Exclusive distributor
DRM Technic has been appointed the exclusive UK distributor for Buhler Technologies from 1st January 2012

New Sensor Additions for Integrated Weather Stations
Specialized Sensing Ltd (UK) announces the WS-401 and WS-601, the latest senor additions to the WS family of compact, integrated weather stations from Lufft GmbH.
The WS-401 and WS-601 combines the all-in-one integrated features of the WS family with a classic tipping bucket rain gauge to provide a precise measurement of rainfall quantity. In addition to precipitation measurements the WS-401 measures air temperature, air pressure, relative humidity and dew point while the WS-601 includes all the measurement parameters of the WS-401 plus an ultrasonic anemometer for wind speed and direction measurements. Their compact, innovative design is ideal for projects where visual impact and low maintenance are a consideration and for applications where flexibility, ease of integration and low power consumption are a requirement.
Using a digital RS485 interface the WS range offers a variety of open communication protocols including ASCII, UMB, MODBUS, SDI-12 and analogue in combination with a DAC. From environmental monitoring stations to building automation projects, the WS family of integrated weather stations offer an innovative climate sensing solution for every project.
