CEM 2021 – Conference and Exhibition on Emissions Monitoring

The 14th CEM conference and exhibition on Emissions Monitoring will take place in the historic city of Kraków in Poland. Kraków is the second largest and one of the oldest cities in Poland with excellent road, rail and airport links for visitors and delegates to attend the meeting.

The CEM event started in the United Kingdom in 1997 and has been held in The Netherlands, Denmark, France, Switzerland, Italy, The Czech Republic, Turkey, Portugal, India and Hungary. Poland was chosen as the ideal location for 2020 due to its economic strength which has been growing steadily over the past 27 years which is a record high in the EU and the most impressive performance in Central Europe .Poland is the eighth largest economy in Europe and is the largest amongst the former Eastern Bloc members of the European Union. Poland has pursued a policy of economic liberalization and its economy was the only one in the EU to avoid recession through the 2007-2008 economic downturn. Poland’s main industrial base is concentrated around the Coal, chemical, Petrochemical, textile, fertilizer, car, shipping and iron and steel industries.CEM 2020 conference

Past visitors and delegates to the CEM events have come from a range of industries around the world that have a common goal and the need to monitor emissions from their plants or processes. At the last CEM, which was held in Budapest, there was a significant increase in both numbers of visitor attendees and exhibitors. Visitor numbers rose by 14% travelling from 42 different countries and exhibitor numbers rose to over 60 representing the main international CEM equipment and service suppliers . The CEM event provided visitors and delegates a wealth of information on Emission regulation, future monitoring challenges, standards and quality procedures, dust measurement, measuring gaseous species, mercury and trace metals monitoring, fence line and fugitive monitoring as well as innovative and new measurement technologies. These themes will be expanded for CEM 2021.

At the 2021 CEM Exhibition and conference, ENVEA experts will held several conferences:

  1. The new MCP directive and the monitoring solutions recommended and adapted for gas monitoring.

    Abstract Information :

    It is established that there are around 143 000 Medium combustion plants in the EU. They are used for a wide variety of applications such as electricity generation, domestic or residential heating and cooling, providing heat or steam for industrial processes and many more. Those plants are an important source of emissions of sulphur dioxide (SO2), nitrogen oxides (NOx) and dust.

    Directive (EU) 2015/2193 on the limitation of emissions of certain pollutants into the air from MCPs known as the Medium Combustion Plant Directive (MCPD) regulates pollutant emissions from the combustion of fuels in plants with a rated thermal input equal to or greater than 1 Megawatt thermal (MWth) and less than 50 MWth. This MCPD regulates emissions of SO2, NOX and dust to air. To comply, it will require to monitor also carbon monoxide (CO) emissions. The emission limit values set in the MCPD apply from 20 December 2018 for new plants and 2025 or 2030 for existing plants, depending on their size.

    The MCPD addresses the potential need for Member States to apply stricter emission limit values in areas where this can improve local air quality in a cost-effective way.

    In order to meet with the requirements of the MCPD, ENVEA Group has launched a wide program of R&D to develop a new generation of NDIR (non-dispersive infrared) Continuous Emission Monitoring Analyser using the most advanced technology to achieve the goal of having a high precision, fast response time and cost effective instrument. Eco-designed, the monitor utilizes the most recent optical and electronic technologies offering increased precision and robustness, while requiring only limited maintenance. The instrument allows simultaneous multi-gas measurement of NOx, SO2, CO, O2, residual H2O, and optionally CO2, CH4 and N2O (greenhouse gases). The optimized design of a converter offers a very flexible and competitive tool to provide reliable NOx measure, as per most of the CEMS regulation using a standard NO analyser (be it multi gas or single gas). The gas monitor allows for a compliant global NOx measurement without the need of a direct NO2 measurement.

    This paper presents from one side, the summary of the Directive and the impact of this new MCPD in the next 5 years with regards to the concerned plants (actual and future) and, from the other side, the technical solution provided with a smart compliant analyser including AMS (automatic measuring system) control functionalities: integrated sampling control, automatic zero and span gas injection, external pump control, system alarms display… Original approach of the metrology is also technically described for a specific case study in a European plant.

  2. Continuous Mercury Emission Monitoring with Long-term Sampling on Sorption Traps – Experiences at flue gas temperatures of 200 ° C

    Abstract Information :

    For the continuous monitoring of mercury emissions, it has been so far common in Germany and Europe to use mercury analysers that can continuously measure mercury emissions in real time, so called Hg-CEMs. In the USA, a long-term sampling method on sorption traps has also been used for several years to continuously monitor Hg emissions.

    In the BAT Reference document (BREF) for “Large combustion plants“, which was published in July 2017, this method is also mentioned as a possible alternative to the use of mercury CEMs. By reducing the mercury emission limit values (ELV´s) in the future, such long-term sampling systems for mercury can be a good alternative to simply and precisely record mercury emissions in the range of 1 µg / Nm3. This would make it easy to monitor the above-mentioned annual emission values of 1 – 2 µg / Nm3. This type of Hg emission monitoring is also described as a possible solution in for certain plants in the published BREF conclusions for “Waste incineration”.

    Due to the increased interest of this method in Europe, the WG8 of the TC264 has adapted the method to European standardization standards in recent years and published it as CEN / TS 17286.

    Since it is a relatively new method, the possible application limits of the method are of great interest. One limiting factor is the maximum flue gas temperature at which this method can be used. If the temperature of the sorption traps is too high, the adsorption capacity of the sorption traps decreases and there is a risk of desorption of the previously adsorbed mercury.

    This presentation describes the use of the long-term sampling system AMESA M in a waste incineration plant with exhaust gas temperatures of approx. 200 ° C. The results of the long-term sampling system were compared with the measurements of an installed mercury CEMs and the standard reference method. In addition to the clean gas, an Hg analyzer was also installed in the raw gas before the flue gas cleaning devices. The goal was to analyze and optimize the efficiency the flue gas cleaning system during various waste loading.

  3. Total Environmental and Process Control in Energy from Waste: Case Study

Abstract Information :

The demands on the Energy from Waste (EfW) sector to achieve and demonstrate ever decreasing emissions of process gases and particulates, both for regulatory compliance and in the interests of social responsibility, requires an effective and complete monitoring solution that can both accurately report and proactively manage emissions to air. This workshop will demonstrate how ENVEA can provide a complete solution which enables Process Operators to improve their process efficiency, control abatement processes, monitor and report emissions to meet regulatory requirements and demonstrate these controls to the local community. With recent draft Best Available Techniques Conclusions (BATC) signalling a further decrease in Emission Limit Values in EfW, this presentation will show how, by utilising precision instrumentation from within the ENVEA range, operators can monitor further back into the process enabling early warnings for changes in dosing or the performance of abatement and being able to more effectively manage their process before breaches of permit conditions can occur. This presentation will also show how complete Continuous Emission Monitoring Systems (CEMS) can help demonstrate to both regulators and the local community the controls that minimise the environmental impact from EfW processes.”
