G. Srivardhan
Srivardhan G is an Assistant General Manager in R&D at Engineers India Ltd. (EIL), New Delhi, and has more than 15 yrs of experience in computational fluid dynamics (CFD), coal-to-liquids (CTL), refinery and petrochemical technology development, and energy efficiency improvement studies. His work also extends to biomass valorization and sustainable process development. He has played a key role in developing several high-impact process innovations, including a novel CDU-VDU configuration delivering nearly 50% reduction in VDU steam consumption and a single-column SWS unit, achieving ~30% lower energy consumption with complete H2S-NH3 separation. He is credited with more than 20 patent applications, 10 of which have been granted, and has been published in many international publications. A BEE-certified energy auditor, Srivardhan is a recipient of the Ambuja Young Researcher Award and the National 2nd Runner-Up prize in the NHRDN Business Simulation Competition (2016). He has actively contributed to more than 50 national and international conferences, including the World Petroleum Congress held in Istanbul, the U.S. and Canada. He holds a postgraduate degree in chemical engineering from IIT Kanpur. The author can be reached at srivardhan.g@eil.co.in.
Boost capacity of SRUs with mixing devices for oxygen enrichment
The requirement for additional sulfur recovery unit capacity in a refinery may stem from hydroprocessing operations; a refinery expansion project; a shift from lighter to heavier, sourer crudes to improve margins; or the need to remove extra sulfur content to meet tighter environmental regulations.
