Similarly most original equipment manufacturers (OEMs) focus on supply of new equipment, its commissioning and target completion of the performance final acceptance test. What happens to the equipment after a few years rarely concerns the OEM as the process parameters or the equipment condition may have changed. Troubleshooting and revamping the equipment and its allied systems to cope up to the required mandates of the Pollution Control Board, is a totally different and highly challenging task. This is owing to the multiple factors that have to be considered, re-engineered, delivered in time and practically executed to the last dot.
