The Challenge and the Solutions

The technology used in the SRSL Bharapar, Gujarat sugar refining is the first of its kind in India. To date, no automation project has been done with the technology.  
Hence to automate plant operations with the available skill sets of engineers in India is a big challenge. To overcome this challenge, SRSL and Yokogawa’s engineers had to use and develop their knowledge base and derive operational theories to configure the control logic and loops.

SRSL's plant operator

To ensure that SRSL’s plant operators could quickly learn and operate the Yokogawa control system, Yokogawa India’s personnel worked closely with the SRSL Controls & Instrumentation Operations Group to design a user friendly interface. The interface features guidance messages that step operators through each procedure for operating the plant, from startup to shutdown.

Through close collaboration with Shree Renuka Sugars Limited, Yokogawa India successfully implemented a cost effective DCS system for stand-alone sugar refinery operations using first of its kind technology in India
