Commercial operation was under way last month at a unique sulfur-processing facility at Reliance Petroleum's Jamnagar export refinery.
The unit, according to designer Black & Veatch, Overland Park, Kan., is the first to pair "two existing and proven technologies in a way that guarantees removal of 99.9% of sulfur from a refinery's acid gases."
The new complex (photo) uses a first-of-its-kind configuration consisting of three sub-dewpoint cold bed adsorption sulfur trains connected to a conventional, amine-based tail-gas treating unit.
Total processing capacity for the new tail-gas treating unit is 2,025 tonnes/day, doubling sulfur processing capacity at the Jamnagar refining complex to 4,050 tpd. Total processing capacity at the Jamnagar export refinery is 1.2 million b/d of a wide variety of crudes ranging from sweet to heavy, with sulfur content up to 4.5 wt %.
