Emissions Monitoring Systems
Working with a1-cbiss, you will benefit from a CEM supplier that has the expertise and experience to apply the relative legislation & permit requirements to your process.
We’ve helped 100s of customers procure the right system, benefit from ongoing proactive maintenance and manage cost control throughout the lifetime of the system.
Introduction to Emissions Monitoring
In the UK, large combustion, and waste incineration plants (EfW and biomass) must operate with a permit within the strict conditions of the Industrial Emissions Directive (IED 2010/75/EU). The IED requires sites to control and reduce the impact of their emissions on the environment.
To monitor pollutants emitted to atmosphere and to ensure measurement parameters are within the permit, this is achieved using a Continuous Emissions Monitoring System (CEMS).
With talk of the BREF regulations tightening the Emissions Limit Values (ELV), it pays to understand which factors maximise system efficiency.
What Services Can You Expect from a1-cbiss?
Legislation & Permit Knowhow
We help companies from the energy from waste and combustion sectors to understand their permit compliance, apply the relevant legislation and implement the correct analytical methods.
a1-cbiss has the experience of successfully delivering CEMS projects. From initial contact, the project is managed to keep you fully up to date with progress, communicate unexpected delays, ensures all equipment is installed to specification and meets timescale expectations.
Following the site survey, our in-house design team discuss your project with the concept team to be able to design a system that meets the needs of your requirements using Best Available Techniques (BAT).
Installation & Commissioning
We undertake Factory Acceptance Tests (FATs) before equipment leaves our premises and perform Site Acceptance Tests (SATs) to ensure total customer satisfaction and adherence to technical specification.
CDAS is a fully MCERTS accredited real-time CEMS data acquisition and reporting software. The data is used to generate reports, alarms or control a process for the purpose of satisfying EN14181.
Problems are less likely to arise if your CEMS have a regular service plan. All customers of a1-cbiss are supported by the UK’s largest service network which offers around the clock reliability and performance.
Flue Gas Emissions Analysers
If your permit dictates that your site requires an accredited analyser, a1-cbiss have a range of MCERTS accredited CEM analysers that guarantee to perform within certified ranges as specified in EN 15267-3.
The process conditions require gas analysers to use the most reliable technology to detect pollutants. a1-cbiss can provide FTIR, NDIR GFC, FID, CLD and TDL as the most accurate technologies which gives you the confidence that the system will perform over time.
Our in-situ and extractive CEM analysers record all the parameters likely to appear on your site permit – NH3, NO, NO2, N2O, CO, CO2, SO2, HCl, HF, CH4, H2O, O2 and TOC. Our FTIR has a large gas library which allows for future upgrades where new gases can be added to your EN14181 reporting schedule.
CEM gas analysers are manufactured by Envea in France. Envea emissions monitors are renowned for their accuracy, reliability, leading-edge technology, and innovation.
Particulate CEMS Analysers
If your permit dictates that your site requires an accredited particulate CEM, a1-cbiss have access to a range of QAL1 approved CEMS specified in EN 15267-3 and, accredited to MCERTS and TUV.
ProScatter™ technology efficiently evaporates any water vapour in a flue gas samples providing reliable and accurate dust concentration measurements.
ElectroDynamic™ technology is unaffected by contamination on the sensor rod (which may cause signal drift in other types of probe electrification devices) and suitable for monitoring conductive dusts which usually coat the sensor such as carbon black.
Reach Across the Widest Stacks for Accuracy
The longest Particulate CEM probes reach up to 15m across the duct.
CEM dust analysers are manufactured by Envea in France. Envea emissions monitors are renowned for their accuracy, reliability, leading-edge technology, and innovation.
Raw Gas Measurement
Control Emissions Earlier in the Process
Control of stack emissions are no longer enough to ensure compliance with regulatory ELVs. Raw gas measurement provides the opportunity to optimise the process by recording the level of pollutants in the gas stream to enhance abatement control.
Lower the Cost of Reagents
Raw gas measurement analysers provide you with the level of pollutants there are in the gas stream prior to abatement. It can, therefore, help control how much reagents are needed without the risk of overdosing (and overpaying).
Dependable, Low Maintenance
TDL method is a non-contact optical, laser technology. The sensor stays protected from any contamination or corrosion and so the maintenance operation and the cost of operation are very low compared to other technologies.
Bulk Flow Measurement
There are many benefits to measuring and monitoring the flow of powders, granules, and dust in bulk handling processes.
Reliable limit level monitoring provides a consistent flow of fuel within the falling chute to guarantee a constant incineration process.
Control Cost of Reagent
Regulate accurate volumes of reagents in the scrubber to manage cost control.
Accurate Flow Speed
Measures the volume of solid materials to regulate speed control.
Identify Blockages to Maintain Efficiency
Flow detectors measure the continuous flow of materials and alert if a jam or blockage has occurred.
Continuous level measurement is necessary.
Flow Measurement Products
Determine Calorific Value
Syngas systems from a1-cbiss measure the constituents of the gaseous fuel produced by gasification or pyrolysis to calculate whether the calorific value is eligible for support under environmental emissions trading schemes.
Syngas is notoriously difficult to monitor due to the dust and heavy tars in the process. Effective gas conditioning and filtration is required to prepare the gas sample ready for analysis.
CDAS is an MCERTS certified data acquisition handling software that collects and processes environmental data for customisable display whilst producing reports to meet site & environmental agency standards.
Guarantee Credibility with MCERTS Certification
a1-cbiss have developed the most advanced DAS package. MCERTS provides the quality, performance standards and test procedures for the development, validation, and maintenance of software. CDAS is fully MCERTS accredited (parts A, B, C1 & C2).
Flexible Data Handling & Configuration
CDAS allows the user to create user defined profiles so you only see what you want to see. You can view data at different stages processing (Raw, Calibrated, Corrected, Adjusted).
Real-Time Trending for Early Warnings
CDAS tracks Emission Limit Values (ELV) to allow you to act before limits are exceeded.
Easily Produce Configurable Site or Agency Reports
Produce timed, mass or percentile reports. EN14181 QAL3 reports.
Prevent Analyser Damage
Gas analysers can be damaged by untreated gas. Conditioning the gas sample using filters and coolers prevents potential damage.
Extend Gas Analyser Life Expectancy
Gas analysers will operate for longer if they are continuously presented with a conditioned gas sample.
Guarantee Consistent Results
If gas is treated prior to sampling, results are likely to be more consistent over time.
