I have an RTO which is proving expensive to run - what can I do?

16. Will we need a fixed VOC monitoring system on my abatement plant?

Ultimately, this will depend on the requirements of your Local Authority. Large oxidiser installations often are required to have fixed FID monitoring (i.e. CEMS – Continuous Emissions Monitoring System) but there is no definition of ‘large’.

Smaller oxidiser installations can be ‘surrogate’ monitored by oxidisation temperature. This is allowed because oxidisation temperature directly affects VOC emissions – higher temperature improves oxidisation and reduces VOC emissions. The relationship between temperature is correlated during abatement commissioning and acceptance trials to determine the control set point and low temperature alarms. The temperature can then be satisfactorily recorded as a surrogate of VOC emissions.

If you would like to discuss any aspect of the information outlined in this question, please contact EPM at contact@epm.uk.com.
