Rapidly increasing lithium production is projected to require several million t/a of sulphuric acid in the next few years, with China, the USA and Australia the main consumers.

The 2030 greenhouse gas emission reduction goals in the European Union are driving oil and gas producers to reduce CO2 emissions wherever possible. This extends to even the incinerator attached to a sulphur recovery unit (SRU). In this article Sulphur Experts review the role of the incinerator, how the three most common European TGUs each affect the demand on the incinerator itself, and the potential reduction in CO2 emissions for a generic facility of each type.

The start of a new year is a traditional time to take stock of the previous 12 months and look ahead to the next. In this regard, CRU’s most recent annual client survey, conducted at the end of December last year, makes interesting reading as to your own concerns for 2025 and beyond. There were numerous responses across commodity and financial sectors, and broadly based worldwide, if slightly skewed towards Europe and North America, but across all of these the key worry for the coming year clearly emerged as trade tariffs and protectionism. This is perhaps unsurprising, given incoming US president Donald Trump’s avowed intent to impose blanket 20% tariffs on all goods entering the US, and up to 60% on China. While most clients did not think tariffs would rise as much as some of Trump’s rhetoric might suggest, most expect rises of 5-10% across the board, and Asian businesses are most concerned. CRU’s most recent position paper on US tariffs highlights some of the internal political and legal challenges in implementing these, but does acknowledge that some rises will be inevitable, and may well produce the kind of reciprocal measures last seen in the previous Trump administration’s trade war with China and the EU in 2018.

As the oil and gas industry focus on new requirements for CO2 recovery, cryogenic processes come under the spotlight. Mahin Rameshni and Stephen Santo of RATE USA discuss the importance of cryogenic processes in acid gas sweetening. Liquefied H2 S and CO2 reinjection is proposed as a cost effective alternative to large sulphur plants.

The ‘golden batch’ refers to stable periods at production plants that consistently generate high quality NPK products at high output. Yara’s Golden Batch digital tool digitises and stores past data from optimal production runs, making these easy to retrieve and implement again in future. Yara’s Marianne Ytterbø provides an overview of this novel digital tool, explains how it was developed, and highlights key benefits.

Emerging evidence suggests that by-products used as fertilizers, particularly ammonium sulphate, may emerge as winners from the EU’s implementation of the carbon border adjustment mechanism (CBAM). In this article, Franck Boher of Upgraid investigates whether by-products can help reshape sustainable fertilizer production in Europe.

Urea revamp activities are performed to achieve improvements of the urea plant. Besides the typical capacity increase there are many options to reduce operation costs, increase plant availability or reduce environmental impact. In this article Marc Wieschalla of thyssenkrupp Uhde GmbH provides an overview of some of the options from an EPC contractor point of view.

Optical gas imaging technology, enhanced by artificial intelligence, offers a groundbreaking approach to monitoring SO2 emissions in real time. Andrés Russu of SENSIA introduces SENSIA’s RedLook solution which offers fully autonomous, 24/7 continuous monitoring of SO2 leaks, providing industries with the tools they need to maintain environmental integrity and operational safety.

Refinery sour water strippers are an often overlooked resource of low GWP ammonia. Martin A. Taylor and Charles L. Kimtantas of Bechtel Energy Technologies and Solutions, Inc. (BETS) show the results of a study on reusing an existing SWS as one of the major systems in a SWSPlus unit for the recovery of ammonia for sale. Relative cost factors will compare a complete SWSPlus unit versus reusing an existing SWS.
