Due to ever increasing environmental regulations, upstream and downstream processing sectors are being required to recover sulfur at higher and higher sulfur recovery efficiencies. At the same time, there has been a trend to limit the CO2 footprint of the facilities that are designed, installed and operated to recover the sulfur that is present in the various sour feedstocks that need to be processed. Jacobs Comprimo® Sulfur Solutions developed and made available to industry the SUPERCLAUS® technology in 1988 and since has improved its performance with the development of the EUROCLAUS® technology in 2000 and continues to improve the technologies to be able to keep up with the severity of the environmental regulations. This paper will present the recent developments of the Jacobs sulfur technologies with the gradual increase in sulfur recovery requirements. Through a combination of optimizations and modifications to the original SUPERCLAUS® technology, it is possible to meet sulfur recoveries ranging from 98.5% all the way up to 99.99% with lower capital cost and CO2 footprint compared to amine-based tail gas treatment units.
