The Environment Agency have written a position paper on the current state of SO2 emissions monitoring using the SRM and P-AMS from a regulators perspective.

Regulatory position paper on sulphur dioxide monitoring, comparing portable-instrumental techniques with manual methods is now available to download.

Sulf-Norm at NEN/INFOMIL 2017

Rod Robinson of NPL recently provided a presentation at the NEN/INFOMIL 2017 that took place in Amersfoort, Netherlands this November.

Rod presented on Improving the measurement of stack emissions – an update on research and standardisation activities in Europe. As well as discussing the Sulf-Norm project, the talk provided an overview of the methods for Stack emissions monitoring in Europe, describing the suite of standards developed by CEN within Technical Committee 264. It also provided an update on recently published standards and the current work programme to develop new standardised methods. This included recently published methods for FTIR and for the measurement of SO2 by instrumental techniques. The current work to develop new standards was summarised and a perspective on future standardisation activities was also provided.

A copy of the presentation can be found here.

Sulf-Norm at CEM India

Rod Robinson of NPL and Tuula Pellikka of VTT recently provided an oral presentation at the Conference and Exhibition on Emissions Monitoring (CEM) 2017 that took place in New Delhi this September.

Rod presented on Improving the measurement of stack emissions – an update on research and standardisation activities in Europe. As well as discussing the Sulf-Norm project, the talk provided an overview of the methods for Stack emissions monitoring in Europe, describing the suite of standards developed by CEN within Technical Committee 264.

The current work to develop new standards was summarised and a perspective on future standardisation activities was also provided. A copy of the presentation can be found here.

Tuula Pellikka provided an oral presentation. In the presentation, Testing equivalency of alternative methods for monitoring of SO2 emissions – the results and the conclusions from these tests were presented.

As part of the Sulf-Norm-project, VTT Technical Research Centre of Finland organized in the spring 2017 tests for equivalency of alternative methods for monitoring of SO2 emissions. The aim of these experiments was to test whether alternative methods (AM) could be used to determine SO2 concentrations instead of existing SRM. The advantage of using automated, instrumental method is that they give real time information about the process concentrations where as wetchemical method gives only average value of the sampling time. Instrumental methods that were used in this test were Fourier Transform Infrared Technique analysers (FTIR), ultraviolet (UV)- fluorescence analysers and non-dispersive infrared (NDIR) analysers.

Tests were carried out at the test bench of VTT. Exhaust gas was produced with engine combusting gasoline. SO2 -concentrations were varied by spiking of SO2 gas to the exhaust gas flow and the concentration range varied from 2 ppm to 200 ppm. All together 25 samples were taken. The results will be analysed using the principles given in the document TS 14793.

Sulf-Norm at AQE2017 

Marc Coleman of project partner NPL recently discussed the challenge presented by the monitoring requirements for SO2 at the Air Quality and Emissions 2017 event 24-25 May. AQE 2017 attracted a wide variety of visitors, all of which shared a professional interest in air and emissions quality.

 

March 2017

VTT, Ramboll and NAB carried out field trials in Finland on VTT’s test bench. The trial lasted for one week and the participants performed intra-laboratory validations according to CEN/TS14793 for alternative methods (AM) compared to SRM, wet-chemical method EN14791.
