Although China remains the world’s largest phosphate producer, it has been overtaken as the largest exporter by Morocco in recent years as domestic producers face continuing restrictions on exports.

The Caspian Sea region is home to extensive sour gas reserves which produce large volumes of sulphur. Exports are difficult, but the Kazakh uranium industry is consuming an increasing amount.

Part 1 of this series on stripper efficiency issues provided a brief history of the CO₂ stripping process and discussed how the invention of the HP CO₂ scrubber back in the 1960s revolutionised urea technology. In part 2 we take a look at how high liquid load can affect stripper efficiency.

Levity Crop Science has a growing reputation as a leader in functional fertilizers, offering novel products that boost nitrogen and calcium efficiency and the crop uptake of micronutrients such as boron, molybdenum and silicon. This has culminated in the recent completion of a new research and development centre near Preston in the UK.

Digitalisation is making a strong impact in the process industry and is providing an opportunity to have a positive impact on the production KPIs. Metso’s Metals & Chemical Processing Business reviews the impact of digitalisation in the sulphuric acid industry today and discusses the concept of a future pit-to-port system within a digital eco-structure.

The Aecometric 3rd generation burner was developed, installed and commissioned for an SRU incinerator with increased stringent demands to reduce NOx emission and lower energy consumption. Mason Lee of Aecometric Corporation reports on the new burner design and performance. The emission test results show a significant improvement in addressing these environmental concerns to achieve low NOx (<50 mg/m3 ) combustion and minimise CO (<200 mg/m3 ) emissions.

Sulphur Experts outline the steps required to determine optimised SRU incinerator operating conditions. Although a proper determination of the ideal SRU incinerator operating conditions for any given facility is complicated by a combination of inconsistent permitting standards and poor understanding of the role of the SRU incinerator, the payoff for incinerator optimisation is a significant decrease in natural gas usage with corresponding savings in operating costs, a decrease in CO2 emissions, and a simultaneous reduction in NOx and SO3 emissions.

Already the world’s largest exporter of sulphur, Abu Dhabi continues to expand its sour gas production and sulphur output.

Biostimulants are emerging as mainstream products with major fertilizer producers – including Yara, Mosaic, Fertiberia and ICL – launching their own biostimulant lines and expanding production capabilities. Smaller innovative companies, meanwhile, such as Azotic and Fyteko, remain the mainstays of the sector and are continuing to being new products to market. Other players such as Den Nouden/GrowSolutions are targeting the expansion of organic fertilizers.

Axens has developed a new titania-based catalyst named CRS 41, which has a much larger porosity than its renowned predecessor, CRS 31 catalyst. Thanks to an improved catalyst manufacturing process and a new recipe, the porosity of CRS 41 has been increased while preserving the mechanical resistance for loading, allowing customers to optimise their capex by either reducing the Claus reactor size or loading volume of TiO2 catalyst.
