The US Environmental Protection Agency (EPA) and the US Department of Agriculture (USDA) have announced the ‘Next Gen Fertilizer Challenge’, a joint EPA-USDA partnership and competition to advance agricultural sustainability in the United States. The competition includes two challenges that seek proposals for new and existing fertilizer technologies to maintain or improve crop yields while reducing the impacts of fertilizers on the environment.

Fluor’s case study of recently constructed ultra-sour gas treating facilities provides new information about the operation of DGA-based AGRUs. B. Lynch and C. Graham of Fluor Corporation discuss how using this knowledge and leveraging the recent improvements to process simulators in the gas sweetening space, Fluor has developed an efficient, flexible, and cost effective solution in the two-stage absorption process to maximise mercaptan removal from ultra-sour gases with minimal equipment.
Troubleshooting and root cause analysis help to identify and solve problems in the operation of nitric acid plants and to prevent future reoccurrences. Johnson Matthey, Casale and Sabin Metal Corporation discuss their approach to solving problems in nitric acid plants to improve plant reliability and efficiency and to avoid unplanned shutdowns, costly replacement of equipment and loss of production.
In spite of continuing safety concerns due to the Beirut explosion, and the rise of the use of urea as a nitrogen fertilizer, ammonium nitrate demand continues to increase in several key markets.
Falling costs for production of hydrogen by electrolysis are encouraging more serious consideration of using recovered carbon dioxide as a feedstock for chemicals and even fuels production.
Although amine solution foaming problems have been studied and reported extensively, direct correlations about the root causes of foaming have not been completely established. This article approaches the problems of foaming from a different perspective, rather than theoretical discussions, the topic is centred exclusively on Amine Experts’ field-related experiences with amine foaming episodes.
The Sulphur Institute (TSI) has announced the selection of Ron Olson as its agronomist. Olson has over 30 years of experience as an independent consulting agronomist as well as 15 years with Cargill and The Mosaic Company. His agronomic consulting company worked directly with farmers and agricultural retailers offering custom soil sampling and soil analysis, and crop management expertise. The company pioneered the implementation of using precision agriculture tools for taking soil samples on a 2.5 acre grid, converting that data to computer maps and linking that data to GPS/GIS technology to develop crop management programs to achieve maximum economic yields. With Cargill and Mosaic he served as Research and Development Manager and led the team that developed the MicroEssentials™ suite of products., which has grown to become the leading commercial sulphur enhanced fertilizer sold globally.
