Case Study: Relocating a Stack Emissions Sample Point to Eliminate Work at Height and Improve Flow Conditions

Problem

Alkali Environmental took over a biannual MCERTS stack emissions monitoring contract from a previous test house. The site operates under an Environment Agency environmental permit that requires periodic isokinetic stack emissions testing at multiple sample locations across the process. On reviewing the existing monitoring arrangements, our UKAS-accredited stack testing team flagged two problems with one of the inherited sample points that were quietly costing the operator money and increasing health-and-safety risk every visit.

Approach

Our stack testing team carried out a sample point design review on the wider process duct system to identify an equivalent monitoring location that would give the same regulatory evidence without the work-at-height burden. We then recommended a relocated sample point in writing for the operator's engineering team.
