NRL adopts online Monitoring and Diagnostic System

The Numaligarh Refinery Limited (NRL) has adopted an online monitoring and diagnostic system for reliability enhancement of make up gas compressors and off gas compressors of the state-of-the-art hydrocracker unit of the refinery.

NRL is the first PSU refinery in the country to adopt this latest global technology by implementing the system in retrofit mode, according to a release issued by NRL today.

The system was designed and supplied by Prognost Systems GMBH, Germany in collaboration with Burckhardt Compression Private Limited.

The three make-up gas compressors and two off-gas compressors of the Hydro-cracker Unit of Numaligarh Refinery, which was commissioned about 12 years back, had the most efficient state-of-the-art technology built into it though 'on line monitoring for compressors' at that time was still in its nascent stage and was not inbuilt in the system as it is now.

This facility will increase productivity, safety, unplanned outages and in the long run maintenance cost of the compressors which are the main equipment in running of a refinery, the release added.

NRL which has patronised new, clean and value added technology, took all initiatives to implement this technology to reap the benefit to improve reliability of their critical Reciprocating Compressors, the moment this technology was proven reliable elsewhere globally.
