Basic and specialist chemical manufacturing processes consist of a number of well-defined process steps which require monitoring for optimisation.
There are numerous individual processes which can be generically summarised as follows:
Trace impurities in product stream
Clean-up and purification
The application of TDLAS gas analysis is of particular interest because it offers operators a truly on-line, continuous and fast measurement of key process indicators with minimal interferences from other process compounds.
Typical process indicators include:
CO, CO2, H2O, O2, H2, HCl, NH3, HF, HCN, CH4, C2H2, C2H4
