Continuous Emission Measurement System

FLSmidth can supply both the production equipment and know-how to produce at a minimum of emission and the emission gas analysis equipment needed to prove the results

Stack Emission
  • Overview

As local legislative demands and standards may vary greatly, FLSmidth is capable of supplying equipment from a broad range of suppliers, being specialised in supplying stack emission analysis to any enforced legislation worldwide (EN, TÜV, MCERTS, EPA, others).

Continuous Emission Measurement Systems (CEMS)
Experience from all parts of the world shows a growing demand for measurement and reporting of emission values from the various Pyro Plants. Previously, stack emission analysis was often only considered to be a measurement dictated to satisfy local legislation demand. Today however, a large portion of the industry imposes its own even stricter standard as a part of a sustainability programme.

Emission gas analysis is defined by local national legislation and performance standards. FLSmidth are able to supply preconfigured solutions to meet European Union and US-EPA standards. All our solutions will be in compliance with standards and pre-approved during site testing of emission control equipment and emission analysis.

ROI: If the plant operating permit is based on emission values, utilisation of an emission system is compulsory by law. If emission control equipment is in use, emission gas analysis can reduce operation cost, e.g., Hg abatement by activated carbon.

Typical components measured: O2, CO, CH4, CO2, NOx, N2O, SO2, THC, HCl,
HF, NH3, H2O, Hg, Dust (PM), Opacity, Flow, Temp, Pressure (Others on request)

Analysis includes any available technique for temperature, pressure, flow, dust and gas analysis (IR, UV, CLD, FTIR, other).

Emission – Protect the environment
Emission analysis does not directly support the production output of the various pyro plants. However, as many production permits are granted based on emission limits and the implementation of online emission measurements, it is in the general a compulsory installation.
The emission system configuration can only be determined after a specific site evaluation in the context of the legal requirements, production permits and plant layout. Most systems are installed in the stack, and the emission application typically requires the utilisation of both extractive and in situ systems. The various analysers are operated according to different principles and require calibration to be effected according to specific procedures and time frames. All emission results must be reported to the authorities according to a specific normalised format, which also documents the operation and correct calibration of the analysers.
Since this task is often a challenge for the plant to handle, an option for a complete plug-and-play solution has been developed. This solution could be provided, in a pre-built on-site unit housing the GASloq CUBE, which handles all needed analysis equipment through one common HMI interface. This setup will take care of the correct handling and operation of all the analytical equipment. This solution can further be extended with a reporting package, called ReportLoq. This dedicated emission reporting system collects all data in a normalised format according to equipment configuration in order to accumulate emission reports based on any averaged time span required.
