• Southern Africa's sulphur and sulphuric acid industries
  Sub-Saharan Africa is a net importer of sulphur, mainly to feed phosphate and metals production. The sulphuric acid picture is complicated by new sulphur burning acid plants and taxation disputes with copper companies in Zambia and the Democratic Republic of Congo, however.

• Water treatment in sulphur recovery units
  As the world moves towards more sustainable processes with minimum impact on the environment, plant designers are forced to investigate new ways of meeting stringent environmental regulations. Comprimo® has developed a solution together with Cool Separations B.V., using an innovative process called eutectic freeze crystallisation for the treatment of water effluent streams originating in SRUs that are difficult to handle by conventional water treatment solutions. T. Roelofs of Comprimo®, B. Brocades and M. Aljirjawi of Cool Separations B.V. discuss the benefits of this technololgy.

• Alloy materials in sulphuric acid plants
  Stainless steel and high-silicon alloys are making inroads in all areas of the sulphuric acid plant. These materials are increasing lifespan, safety, and energy efficiency both through their intrinsic properties, and through the additional flexibility they offer in equipment design. In this article, DuPont Clean Technologies and NORAM discuss strategic choices for long-term corrosion resistance and how using alloy materials for the equipment in sulphuric acid plants can benefit the producer and increase the productivity and lifetime of the plant.

• OXYSULF: lowering emissions
  KVT has upgraded its wet sulphuric acid technology to improve plant efficiency and availability in various applications. Setting a new milestone in the desulphurisation of waste gases, OXYSULF is a high energy efficiency, zero waste process that achieves exceptionally high sulphuric acid concentrations and sulphur recovery rates.

• New hybrid sulphuric acid process
  Allowable emissions of sulphur-containing gases are continually being reduced as a result of increasingly stringent environmental regulations. This has an impact on all new and operating sulphuric acid plants, where optimised operations and improved designs are required to meet the new emissions targets. NORAM and CPPE have formed an exclusive alliance and have introduced the Hybrid Sulphuric Acid Process (HSAP) to address this issue. This article presents some of the technical features of the NORAM-CPPE HSAP and discusses a number of performance parameters for industrial applications.
