Continuous Emissions Monitoring
System Solutions for a Cleaner
Environment

Any new installation seeking a permit will need to
comply with the Industrial Emissions Directive (IED).
The EA are looking at bringing all existing
permitted sites under the directive.

Continuous Emissions Monitoring Systems (CEMS)
are used to continuously collect, record and report
data from industrial process operators that produce
emissions to air.

The IED supersedes seven directives under one
directive, creating a more simplified legislative
framework:

CEMS are used as a means to comply with stringent
emission limits as regulated by the Environment
Agency (EA).
Under the Environmental Permitting Regulations, the
EA or local council will refer to European Legislation,
the Industrial Emissions Directive (IED 2010/75/EU).
Sites are required to continually measure emission
parameters from their chimney-stacks to ensure that
they are compliant, as defined in their site permit.

Integrated Pollution Prevention Control (IPPC)
Large Combustion Plant Directive (LCPD)
Waste Incineration Directive (WID)
Solvent Emissions Directive
And three Titanium Dioxide Directives

Under the new changes set by the IED, large
combustion plants will be affected by the new
emission limit values (ELVs). This will be particularly
significant to the future of coal fired power stations.

Who Regulates the CEMS Market?
In 1998, the EA introduced the MCERTS scheme to
provide tighter controls for emissions to air
including a technical specification that CEMS had to
meet.
The criteria of the scheme included: detection
limits, response time, linearity, zero and span drift
etc. A requirement of the scheme, any CEMS
equipment used to monitor emissions must also be
approved and certified.

CEMS Overview
Whether your process is hot, wet, dry or dusty, we
offer in-situ and extractive multi-gas
analysers to be integrated into complete
systems.

In-situ Technique
In-situ gas analysers have a very short response
time as they directly measure gas from the stack.

Extractive Technique
Sample gas is extracted via a probe, conditioned
and transported by a sample line to the gas
analyser which is housed in an air conditioned
GRP shelter.
The standard extractive CEM system consists of:
n Sample probe
n Filter
n Sample line (umbilical)
n Gas conditioning system
n Calibration gas system
n Gas analyser

Typical monitored emissions include:
n Sulphur Dioxide
n Nitrogen Oxide
n Carbon Monoxide
n Carbon Dioxide
n Hydrogen Chloride
n Ammonia
n Particulate Matter
n Mercury
n Volatile Organic Compounds
n Oxygen
n Dioxins
n CEM systems can also measure

temperature, air flow, pressure,
and moisture

| Where are CEMS
Installed? |

Most CEMS installations are utilised in
applications where power is generated or where
waste is burnt. Fuel consisting of fossil fuels,
gas or waste is burnt or heated at very hot
temperatures to produce heat or power or both to
generate electricity.

Coal Fired Power Plants An Uncertain Future?
In fossil fuel powered plants, environmental protection
has seen a greater focus. Although the UK has seen
air pollution declining since the 1970’s, the IED has
demanded a market for technologies to address
Nitrogen Oxides (NOx) and Sulphur Oxides (SOx).
In general, power plants with a greater capacity
than 50 MW are required to measure NOx and SOx
continuously plus dust and particulate matter (PM)
emissions.
Under the new rules set by the IED, coal-fired power
stations must either comply with certain emissions
limits or opt out – Operators choosing to opt-out are
then allowed a certain number of hours of operation
before they must be shut down.

Energy from Waste A Solution to the UK’s Waste
Problem
The UK is faced with the problem of disposing waste
as many landfill sites are full. An increased number
of EfW sites would decrease the amount of waste
being sent to landfill significantly. EfW’s are regarded
as a solution to the growing amount of waste in the
UK generating up to 70MW of energy.
Municipal thermal treatment sites are required to
typically measure SOx, NOx, CO, HCl, NH3, VOC and
TPM which now fall under the IED.
EfW sites are seen as a ‘greener’ method of
waste disposal as they reduce the emission of the
greenhouse gas and methane produced during
waste composition from organic matter in landfill
sites.

Biomass A Greener Alternative
The UK government supports biomass, as a lowcarbon form of power generation compared with
fossil fuels. The trees and plants used as fuel absorb
carbon dioxide from the atmosphere as they grow,
so if they are regrown under environmentally sound
conditions, burning them results in a net carbon
saving as it displaces coal and gas.
However, green campaigners point to problems with
sourcing sufficient quantities of biomass, much of
which has to be imported, and say that without strict
regulations, growing trees and crops for biomass
can lead to deforestation in developing countries.

| Solution to
A
t
he UK’s
Growing Waste
Problem? |

Currently, the UK generates around 30 million
tonnes of municipal waste each year. Of that:
n 35% is recycled or composted;
n 10% is used to recover energy (EfW);
n 55% is sent to landfill
The growing volume of waste, a shortfall of landfill
sites and increasing energy prices are making
Energy from Waste an obvious solution for a
cleaner environment whilst filling the gap
of power generation left by the coal fired power
stations.

Are We Facing an Energy Crisis?
The majority of the UK’s electricity comes from coal
fired power plants. In 2011, the IED came into force.
The directive gave high polluting coal fired power
stations a period of grace to comply with the new
requirements highlighted in the directive. If sites
choose not comply, they are faced with closure.
The IED will require non-compliant power plants to
close by the end of 2016 or after 20,000 operating
hours. With low coal prices making coal-fired power
plants more profitable than gas, many time-limited
coal-fired power plants have raced through their
allocated hours already and will close this year.
Estimatations suggest that over 12000MW of
generating capacity could be lost from the national
grid following the closures in 2016.
There is a real possibility that we could be facing a
‘lights out’ situation.

Why Landfill Isn’t Sustainable:
n EU Landfill Directive requires the amount of

waste to be reduced
n In 2014, landfill taxation rates have increased

from £72 per ton to £80 per ton to encourage
diversion from landfill
n Majority of landfill sites are full

n Methane gas produced by landfill has a GWP

of 21 which means it offers 21 times the
greenhouse warming threat than CO2

Incentives for Capturing Syngas from
Gasification Process
The Renewables Obligation (RO) places a
commitment on UK electricity suppliers to source
an increasing proportion of electricity they supply to
customers from renewable sources. The gasification
process converts municipal solid waste into a usable
synthetic gas, or syngas.
Renewables Obligation Certificates (ROCs) are
issued to accredited generating stations based
on net renewable generation. The fuel is sampled
using the process agreed during the accreditation
process, factoring in the calorific value of the fuel
being burnt, and this is then used to determine the
renewable generation for ROC claim purposes.
More efficient plants will receive up to 2 ROCs per
MW/hour of electricity produced.

We have been using a1-cbiss since the plant was built for their expertise, technical guidance and
market leading equipment. The equipment we have onsite is the MIR-FT system combined with a
G52M FID and the a1-cbiss data acquisition software CDAS Elite. The complete CEM system has
proven to be very reliable and dependable over the years. One of the key benefits to us is the CDAS
elite software package which is easy to use and extremely flexible meeting all our site requirements.
The a1-cbiss engineers offer exceptional support, as well as being professional and knowledgeable.
The a1-cbiss legislative consultancy approach has been invaluable and helped contribute to us
achieving one of the highest OMA scores in the industry.

| Case Study |

Power Industry
The background
Because of ageing equipment and increasing issues
surrounding reliability, one of Europe’s leading
power suppliers decided to roll out a series of site
upgrades to replace their continuous emission
monitoring systems (CEMS) at a coal fired power
station and two gas turbine sites across the UK.
The challenge
1. o supply CEMS that complies with the
T
requirements of MCERTS, the large combustion
plant directive (LCPD) and the industrial emissions
directive (IED), which is due to be enforced in
2016
2. o include a system redundancy option at the coal
T
fired power station to prevent any downtime

Design and build

3. o monitor temperature, pressure and flow
T
measurement directly from the flue and establish
communications between the analysers and Data
Acquisition Reporting Software
4. he coal fired power station required the systems
T
to be installed in the main exit flues (within one
concrete windshield), at a height of 75 meters
above ground level
5. he incumbent systems were not provided by a1T
cbiss, therefore a1-cbiss would have to prove that
their solution, service and support is superior to
the incumbent supplier

For the gas turbine site, a1-cbiss proposed MIR9000
CLD chemiluminescence and infrared multi-gas
analysers that monitor extracted samples on a dry
basis, using a SEC sample conditioning system.
The SEC sample conditioning system comprised
of the same elements as used in the MIR9000
system. The CLD system fully complies with the
standard reference method (SRM) EN 14792 for the
measurement of NOx. The CLD also has MCERTS
certification that complies with the new limits in the
IED.

Installation and commissioning

The solution
At the coal fired power station, a1-cbiss proposed
an MCERTS accredited MIR9000 infrared multi-gas
analyser that monitors extracted samples on a dry
basis, using a SEC sample conditioning system.
The SEC sample conditioning system comprised
of an in-situ probe, a permeation dryer unit and a
temperature, pressure and flow module
integrated into the same probe. A permeation dryer
eradicates the requirement for long lengths of
heated line.
The MIR9000 system MCERTS accreditation is
based on the Emission Limit Values (ELV) of the
waste incineration directive, and subsequently future
proofs the site for the ELV change when the IED
comes into force in 2016.
Using a single probe for measuring all of the
required parameters reduced the number of
penetrations in the flues and consequently lowered
the cost of installation.
The option for system redundancy was addressed
by proposing a fully automated change-over system
with an additional MIR9000 analyser. The system
would be fully controlled by the CDAS software,
therefore requiring minimal user intervention and
eliminating any risk of downtime.

Service support is integral to the a1-cbiss offering.
With the largest service network in the industry and
nationwide coverage, the dedicated team of service
engineers provide service, repair maintenance on
all equipment supplied.
The result
a1-cbiss manage all aspects of the project from
design build, installation and commissioning,
through to on-going service and support.
The coal fired power station saw the installation
of nine MIR9000 multi-gas MCERTS accredited
analysers comprising of four duty MIR9000 systems
and 1 standby MIR9000 with a changeover system
for redundancy. The analysers are integrated into a
purpose built enclosure, all communicating via the
MCERTS certified CBISS Elite Data Acquisition
Reporting software (CDAS) which also incorporates
the IVIS hardware panel allowing for QAL 3
functionality.
The gas turbine site saw the installation of seven
MIR9000 CLD multi-gas analysers. Again the
analysers are integrated into a purpose built
enclosure, all communicating via the MCERTS
certified CBISS Elite Data Acquisition Reporting
software (CDAS) which also incorporates the IVIS
hardware panel allowing for QAL 3 functionality.
