• Abu Dhabi: sulphur giant
  In a few short years Abu Dhabi has grown to become the world's largest sulphur producer and exporter, and new sour gas projects will lead to additional sulphur recovery capacity, provided they can overcome economic challenges.

• SO2 emissions control
  Legislation to control emissions of sulphur dioxide continues to tighten, via vehicle exhausts, and refinery and smelter emissions, leading to increased recovery of both sulphur and sulphur dioxide.

• Unlocking the potential of gas processing assets
  G. Bowerbank and W. Blas of Shell Catalysts & Technologies discuss low cost strategies to maximise value at existing gas processing facilities. Changing solvents, introducing advanced column internals or a combination of both are relatively simple and cost-effective options for boosting production or revenue with minimal investment.

• One size does not fit all
  K. Hanlon Kinsberg and J. Lewis of Comprimo review the main approaches for mercaptan removal in gas processing plants, based on past project experience and generally accepted industry practice.

• Two-stage absorption for mercaptan removal
  Fluor's case study of recently constructed ultra-sour gas treating facilities provides new information about the operation of DGA-based AGRUs. B. Lynch and C. Graham of Fluor Corporation discuss how using this knowledge and leveraging the recent improvements to process simulators in the gas sweetening space, Fluor has developed an efficient, flexible, and cost effective solution in the two-stage absorption process to maximise mercaptan removal from ultra-sour gases with minimal equipment.

• Meeting sulphur specs
  An advanced mecaptan removal process has been developed and implemented by RATE. The RATE-Oximer process is an oxidative air-based regeneration process, designed to remove mercaptans from liquid and vapour phases. M. Rameshini of RATE describes the key features of the process and its applications.

• New self-cleaning sulphur strainer
  For the protection of nozzles in sulphur forming plants it is important to prevent larger particles from entering the forming machinery and possibly blocking the nozzles. In normal operation, pipeline strainers are used. Sulphurnet has designed a new system which is suitable for continuous or batch operations and has lower maintenance costs. J. Hermans of Sulphurnet introduces the self-cleaning sulphur strainer.

• Preventing explosions in molten sulphur tanks
  Undegassed molten sulphur can contain several hundred ppmw H2S. If the headspace in the storage tank is stagnant, the H2S can accumulate in the vapour space above undegassed liquid sulphur to dangerous levels. Sweeping and blanketing systems are commonly applied to manage the explosion risk in the headspace of molten sulphur storage tanks. D. J. Sachde, C. M. Beitler, K. E. McIntush, and K. S. Fisher of Trimeric Corporation review these approaches, outlining the benefits and limitations, design considerations, and industry experience/guidance for each approach. Calculation methods for natural draft flow of sweep air are also presented.
