• Sulphur storage – environmental considerations
  The long-term storage of sulphur can lead to fugitive dust and sulphuric acid contamination of ground and water if not handled correctly. What are the risks and how can they be ameliorated?

• Countdown to MARPOL
  The new IMO MARPOL (Maritime Pollution) 0.5% limit on sulphur content of marine fuel is due to come into force on January 1st 2020. This article looks at the likely consequences for refiners, ship owners and the sulphur industry.

• Sulphuric acid markets – shifting fundamentals
  Declining imports of acid from China and increasing demand from Morocco, and eventually the Philippines and Peru are coming at the same time as the prospects of China becoming a net exporter.

• A review of AGIS VIII
  The Acid Gas Injection Symposium (AGIS) is the only conference that focuses on the injection of CO2, H2S, and mixtures of the two either for disposal or for enhanced oil recovery. The eighth symposium was held in Calgary at the end of September 2019. Although AGIS covers three technologies: (1) acid gas injection (AGI), (2) carbon capture and storage (CCS), and (3) the use of CO2 for enhanced oil recovery (EOR), in this review Y. Wu of Sphere Technology Connection and J. J. Carroll of Gas Liquids Engineering focus on the AGI aspects of the Symposium.

• BTX destruction in the Claus thermal oxidiser
  Acid gas enrichment (AGE) is a commonly employed technique that can be used to increase the H2S content of acid gases being fed to a sulphur recovery unit (SRU). In some cases, the AGE vent gas, enriched in CO2, is routed directly to the thermal oxidiser. If the lean acid gas being enriched contains appreciable levels of benzene, toluene, and/or xylene (BTX), it is possible for BTX to slip through the amine of the AGE, along with the CO2, and be fed to the thermal oxidiser. However, experimental data pertaining to conditions required for BTX destruction within the thermal oxidiser are lacking. In this context, ASRL has investigated the impact of various BTX concentrations in the thermal oxidiser. D. Li, N. I. Dowling, C. B. Lavery and R. A. Marriott of Alberta Sulphur Research Ltd discuss the experiments and the results.

• Modular acid plant SAP250M
  T. Schüller of Outotec provides insight into Outotec's strategic initiative to provide the sulphuric acid industry with a standardised modular sulphur burning sulphuric acid plant, based on Outotec's recent contract execution experience for a similar project in Central Africa.

• Biological SRU under turndown conditions
  XTO Energy's East Texas natural gas operations operate a skid built biological desulphurisation unit (Thiopaq O&G) to treat amine acid gas from an AGRU unit which removes CO2 and H2S from sour gases gathered from approximately 800 wells. It was found that the SRU showed continued strong performance in dealing with significant turndown of the feed gas flow rate (30% of design) and sulphur load (17% of design). J. Klok, R. de Rink, G. van Heeringen, J. Timmerman of Paqell B.V. and P. Shaunfield of XTO Energy Inc. discuss the operational data and lessons learned from recent years of operation.
