M. Rameshni and S. Santo of RATE discuss different sour water stripping gas processing options, depending on contaminants in the sour water streams and site-specific requirements.

New low-cost metal oxide solid scavengers for hydrogen sulphide (H2 S) removal from wet and dry natural gas have been developed and deployed at commercial scale. The desulphurisation process uses a proprietary sorbent chemistry to achieve a high sulphur capacity and removal efficiency. G. Alptekin, F. Kugler and M. Schaefer of SulfaTrap LLC describe the new technology and its performance.

An update on the latest in fertilizer ship loading, handling, bagging and blending, including new contracts, company news and advances in technology.

Anglo American is developing the Woodsmith project in northeast England. This will access the world’s largest known deposit of polyhalite, a natural mineral fertilizer containing potassium, sulphur, magnesium and calcium – four of the six nutrients that every plant needs to grow.

Buss ChemTech AG offers the international phosphate industry a robust solution to create added-value products from fluorosilicic acid (FSA). Thomas Dahlke, the head of the company’s process engineering department, and Emre Sen, sales manager for fluorine technologies, explain how this can be done in a sustainable manner.

India’s power and renewable energy minister RK Singh has placed draft plans before the cabinet for the country’s refining and fertilizer sectors to switch to renewable ‘green’ hydrogen feeds. Other energy intensive sectors such as steel and transport are likely to follow. The policy suggests that refiners must have 10% of their hydrogen consumption generated from renewable electricity by the end of financial year 2023-24, rising to 25% by 2030. The comparable figures for ammonia/urea production are 5% and 20%, respectively. India is pursuing some of the world’s most ambitious renewable energy targets of 175 GW of renewable energy capacity by the end of 2022 and 450 GW by 2030.

China is the world’s largest importer of sulphur, mainly to feed domestic phosphate production. Sour gas in Sichuan and new refinery production, coupled with rationalisation in the phosphate sector are all leading to reduced imports, while new smelters are increasing sulphuric acid production and reducing the need for pyrite-based and sulphur burning acid production.

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

As well as Morocco, Egypt, Algeria and Tunisia all have major phosphate industries, and all of these countries have plans to expand their capability to extract and process phosphates, though Algeria and Tunisia remain hampered by political instability.
