Air Quality Monitoring

The San Lorenzo plant has its own strict environmental monitoring program for the air component. It has an air quality monitoring plant that constantly measures online parameters such as PM10, SO2, NOx, O3 and CO.

In the case of particulate material (PM10), the plant has a beta analyzer (continuous), and has continuous analyzers for gases installed on a rack inside a monitoring booth with the appropriate temperature and conditions. The data is stored in a data-logger with a storage frequency of every 5 minutes.
