• Indonesia: the rise of domestic smelting
  The Indonesian government's decision to enforce the processing of more copper and nickel ores domestically rather than export them to China has led to the rapid development of domestic smelter capacity as well as nickel acid leaching projects.

• Degradation of chemical additives under downhole conditions
  When producing from shale reservoirs, technologies such as horizontal drilling and hydraulic fracturing have been used successfully to access hydrocarbons that otherwise could not be. A less publicised issue in producing from certain hot shale gas reservoirs (T > 100°C) is the presence of H2S and organo-sulphur compounds in the production fluids. In trying to understand the non-biogenic sources of H2S, Alberta Sulphur Research Ltd has been involved in studying the decomposition of chemicals used in hydraulic fracturing when exposed to high temperature and high pressure. R.A. Marriott, J.J. Marrugo-Hernandez and R. Prinsloo of ASRL discuss the findings of the study.

• Upgrade of Claus TGTUs
  BASF has developed a new generation of promoter system compatible with MDEA solutions named OASE® yellow. The new promoter system increases the selectivity and capacity of the amine solvent, resulting in improved performance of tail gas treating units and allowing the processing of more sour crudes. A. Kern and G. Vorberg of BASF discuss two case studies demonstrating the benefits of OASE yellow.

• Design challenges of mega acid plants
  What are the limits for future single stream sulphuric acid plant capacities? H. Storch, C. Bartlett, and S. Mohsler of Outotec discuss design considerations for large capacity sulphuric acid plants with reference to the world's largest acid plants built to date.

• Start-up, shutdown and turndown
  With the ongoing changes in gas field and refinery feedstock compositions, many sulphur recovery units around the world are facing turndown scenarios to such an extent that it is difficult to meet stringent environmental regulations. Equipment and instrumentation behave differently under turndown conditions, and not always in ways that are desirable. Start-ups and shutdowns can place demands on the equipment that are more severe than years of normal operation. In this article, Optimized Gas Treating, Sulfur Recovery Engineering and Comprimo share some of their learnings and experiences of these scenarios.
