Division BAT 5 BAT is to monitor the relevant process parameters linked to pollutant emissions, at catalytic cracking and combustion units by using appropriate techniques and with at least the frequency given below.
United Kingdom
| N and S monitoring in fuel or feed may not be necessary when continuous emission measurements of NOX and SO2 are carried out at the stack. | |
| Description | Minimum frequency |
|---|---|
| Monitoring of parameters linked to pollutant emissions, e.g. O2 content in flue-gas, N and S content in fuel or feedf1 | Continuous for O2 content. For N and S content, periodic at a frequency based on significant fuel/feed changes |
