Meena Chauhan, Head of Sulphur and Sulphuric Acid Research, Argus Media, assesses price trends and the market outlook for sulphur.

The extensive sweep of financial sanctions against Russia in the wake of the invasion of Ukraine, coupled with Russia’s position as the leading exporter of numerous commodities means that the impact of the 2022 price shock may be worse than 2008.

With climate change looming there is an increased focus on reducing the environmental footprint of the production of fertilizers. The use of renewable energy/green hydrogen is one way to make the fertilizer industry more environmentally sustainable. In this article, Rene Dijkstra of Chemetics introduces the Green Fertilizer Complex. This practical solution integrates an oxygen-based sulphuric acid plant using the Chemetics’ patented CORE-SO2™ process with a green hydrogen and ammonia facility to deliver low cost, low emission, and carbon-free phosphate (MAP/DAP) and/or sulphate (AMS) based ammonia fertilizers.

The fourth SulGas Conference organised by Three Ten Initiative Technologies took place 1-4 February as a virtual event. Selected highlights from some of the presentations from SulGas 2022 are given below.

A shortages of highly pure nickel is driving major new investment in high pressure acid leaching plants, especially in Indonesia, with a significant impact upon sulphuric acid and sulphur demand.

As all industries come under pressure to decarbonise, are there ways to reduce the carbon footprint of sulphur recovery operations?

A sulphuric acid plant forms critical material and energy interfaces with other plants in several different types of chemical and metallurgical complexes. Shailesh Sampat of SNC-Lavalin discusses how the acid plant design is customised to match the product mix and the energy requirements of the complex to provide the optimum solution for energy and material requirements.

Ricardo L. Sepulveda of PegasusTSI reviews options to decrease the CO2 footprint of a fertilizer industrial complex and illustrates the technical and economic feasibility of utilising clean energy from a sulphuric acid plant in a fertilizer complex to produce green hydrogen, which in turn can be used to produce green methanol or green ammonia.

Developments in the Russia-Ukraine conflict is going to be a key influence for the sulphur market through the year. The potential loss of Russian sulphur to key import markets such as North Africa and Latin America is likely to lead to trade flows increasing to these regions from the Middle East and North America.

A new cost-effective alternative sulphur technology, providing a simple and robust process to achieve an overall sulphur recovery efficiency of 99.9+% is being developed by Saudi Aramco. J. P. O’Connell and I.A. Alami of Saudi Aramco discuss the new technology, its benefits and current stage of development.
