ADNOC Sour Gas Company Ltd owns and operates the Shah Gas Processing Plant facilities comprising of 1280MMSCFD of sour gas treating facilities with H2S content of ~24 vol%. There are 4 identical, parallel Claus Sulphur Recovery and Tail Gas Treating Units designed to handle acid gas for a nominalԹ sulphurԹ processing capacity of almost 3,000 TPD per unit (12,000 TPD total).
ADNOC Sour Gas (ASG) floated a tender for requirement of catalysts to their Claus& TGT reactors in Sulphur Recovery Units (SRU).Թ The tender is expected to last for 5 years as all 4 SRU trainՉs catalyst is expected to replace during this period.
It was extremely important for AIMS to win this tender as this would control all the business for CatalystՉs supply to ASG for the next 5 years. Competition was stiff as ASG is currently using a different Catalyst for the Claus reactors and it would be a big challenge for AIMS to replace an existing supplier.
AIMS began working in order to provide a bid consisting of Catalysts as well as Activated and Ceramic Support Balls for both Claus & TGT. Թ AIMS utilized its expertise in Sulfur Technology in working a competitive strategyԹ by changing the ratio of Alumina and Titanium Catalysts in the first reactor of each train.Թ The benefit of this strategy would result ~ 15 to 20% savings in overall costing.
This strategy is a win-win for both ASG & AIMS in saving the catalyst cost while not compromising the conversion and Catalyst life cycle.
