The inaugural Argus Sustainable Fertilizer Americas Conference is being held at the Grand Hyatt Tampa Bay, Tampa, Florida, USA, 5-6 June 2023.

The Sustainable Fertilizer Academy (SFA) offers everyone within the fertilizer industry access to education on sustainability via a certified e-learning programme. More than 150 students have registered to date and over 40 alumni have graduated from the academy since it opened in September last year.

Evaporation and crystallisation are widely used throughout the fertilizer industry. These powerful production processes are helping fertilizer manufacturers diversify their product portfolios, improve profitability and meet sustainability goals.

With the challenges facing the global refining industry, refiners should review their current practices to see how they can stay competitive and continue to thrive in today’s market. This means improving operational efficiencies and producing products at a lower cost, whilst ensuring performance and safety. Brian Visioli of Evonik explores the development of catalyst reuse and how recycled hydroprocessing catalysts can be successfully applied in tail gas treating units to deliver cost and performance gains.

Liquid fuels will be with us for decades to come, but refiners will be pushed to decarbonise their activities, via greater use of biofuels, and green/blue hydrogen use.

The sulphuric acid process is virtually carbon free and, as such, it is important to consider the energy requirements of the associated industrial complex before deciding upon what form the energy should be exported from the acid plant. In this article, Stefan Braeuner, Stefan Mohsler and Anne Mohsler of Metso Outotec use case studies to exemplify the need to fully analyse the local conditions at site before a decision is taken on a specific flowsheet.

Most processes involving sulphur, from smelting to refining, produce sulphur dioxide as a by-product. Regulations continue to tighten on industrial SO2 emissions worldwide, leading to greater recovery of sulphur and sulphuric acid at these sites.

Rising costs of fossil fuels in many markets, including coal in China and high gas costs in Europe are pushing up ammonia production costs. Can the falling cost of electrolysis make green ammonia production cost competitive in the near future?

In the current energy transition era, the oil and gas industry is focusing on lowering its carbon footprint while generating green energy resources such as blue hydrogen. In this article, Thomas K. Chow, Marcus Weber and Denny Li of Fluor Solutions/Goar, Allison & Associates, L.L.C. demonstrate how SRU/TGTU plants within sour gas facilities can facilitate the capture of CO 2 and generate H 2 by implementing advanced sulphur recovery technologies.

Due to the inherent nature of the renewable power, sizing eSyngas plants powered with renewable energy brings complexity normally not faced by natural gas-based facilities. In this article, Dr Raimon Marin and Dr Solomos Georgiou of AFRY discuss the application of AFRY’s state-of-the-art modelling tool to optimise the size and production of a green hydrogen system and a green ammonia plant based on given renewable power profiles and their associated variability (e.g., hourly, daily, seasonally, and annually).
