Reliance Chemical facility achieves
'live' upgrade
ABB System 800xA Extended Automation was selected by Reliance Industries (RIL) for the control system upgrade at their plant for the production of linear alkyl benzene (LAB) at Patalganga
RIL is India's largest manufacturer of LAB with an output of 110K tons per annum The Patalganga facility operates in technical collaboration with UOP (USA), the process licensor

The LAB product produced is marketed under the trade name "Relab".
The LAB plant was commissioned in 1988 and was equipped with ABB MOD30 controllers that were linked to a VAX system.
With subsequent de-bottlenecking to increase plant capacity, the control system was expanded to a MOD-300 DCS using ABB Model B and SC controllers.

Later, AC460 controllers were added.
The complete control system consisted of approximately 1,400 I/O points.
As the Model B and SC controllers became dated and more costly to maintain, RIL decided to upgrade the complete control system with a new generation, state-of-the-art distributed control system.
The 800xA system was selected with consideration to several factors.
One was the fact that it provides a Windows platform, as well as highly reliable 800 Series I/O modules.
Additionally, it features Open System architecture and OPC compliance.
Also, service support is available, and the company is familiar with the 800xA system since one had been installed at the RIL Hazira complex.
The Patalganga LAB plant system runs a suite of Industrial IT software for operations, maintenance and management of the asset.
The hardware portion of the system has many redundant features that help ensure a high degree of operability.
The transition from the earlier control system to the 800xA system was well planned and went smoothly without a single upset or shutdown of the facility.
It was conducted in two stages.
The Front-End area of the plant was selected for upgrading first.
Open loops were transferred, one by one, to the 800xA system over a period of time.
Then, complex loops followed, receiving special care.
Once the Front-End area was commissioned, the plant entered an observation phase for six months to monitor how well the new system would perform.
Satisfied with its operation, the Back-End area was transferred in similar fashion.
During the period between commissioning the front-end and back-end areas, Advanced Process Control (APC) from Aspentech was implemented in the system.
Ranjan Bhattacharya, Vice President of RIL for instrumentation at the Patalganga facility, noted, "This was a unique project for RIL in that it was the first ever implementation of an on-line evolution of one of their petrochemical plant automation systems".
He further explained, "We have successfully completed the up-grade of the LAB DCS from MOD-300 to the ABB 800xA.
We congratulate the ABB team for achieving the objective of the project to our satisfaction".
