The refining industry continues to pivot towards Asia, with knock-on effects for sulphur output.

Intermittent supply from China due to export restrictions and US duty changes have kept markets guessing over the past couple of years, and there is no sign of that changing.

Aparna Saiju and Nishevitha U G of SLB-MPS explore the concept of energy optimisation using power recovery turbine (PRT) technology in amine sweetening units, focusing on its potential benefits, implementation strategies, and environmental implications.

A plant operating a spent acid decomposition furnace as part of its sulphuric acid production facility desired to increase acid production primarily by processing additional spent acid while making minimal modifications to the plant equipment and operations. The Messer solution entailed introducing oxygen in two steps, both as an enrichment to the combustion air and by direct injection into the furnace. The resulting performance improvements exceeded the project objectives for acid production and spent acid decomposition, without increasing NOx emissions. This paper provides a summary of the system start-up and tuning and presents the resulting improvements and lessons learned.

Readers of Sulphur magazine have always been at the forefront of operating, designing, researching, and troubleshooting process units in the sulphur value chain. However, more recently, with the emergence of net zero initiatives by international conventions and governments (e.g. the Paris agreement), the push for decarbonisation in our industry has been on the rise. Ganank Srivastava of Bryan Research & Engineering takes a look at the bigger picture and examines ways to reduce carbon footprint in sour gas facilities.

A look at the safety challenges that face developers of ammonia-powered shipping vessels before it can become used more widely as a low carbon fuel.

Casale, Saipem, Staicarbon & Toyo Engineering Corporation showcase a selection of innovative technologies that have recently been brought to the market.

The reliability of primary reformers is a key issue for syngas plants. In this article O. Chung, N. Goodman and C. Thomas of Quest Integrity describe the damage mechanisms and material limitations that impact the reliability of reformer outlet systems and the improvements that may be implemented.

Indian producers have begun producing nanofertilizers at scale with the backing of the national government, as part of efforts to improve nutrient use efficiency, limit fertilizer subsidies and reduce fertilizer import dependency. But some scientists have questioned the claimed benefits and the overall efficacy of these novel crop nutrient products.

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.
