Assuming that the original raw material contains 0.5ppm nitrogen, subtracting 0.5 represents the extra nitrogen compared with the original
This 0.5ppm is the nitrogen content allowed for normal production, which is determined by the severity of the process operation.
1ppm of nitrogen consumes 2.5ppm of chlorine, so it is not “× 2.1” but “× 2.5”
If nitrogen poisoning occurs, you can inject more chlorine to restore the catalyst activity first, without strict calculation.
