In August 2020 the tragic explosion of ammonium nitrate fertilizer in the port of Beirut caused many fatalities and injuries. This was a wake-up call for the entire industry to review the design of plants and storage facilities, as well as the procedures for plant operation and the handling of products. The key factor for safe new installations is the process design: the right choice of unit operations, operating temperatures and pressures, the control of process variables and the design of key items of equipment. A modern ammonium nitrate (AN) plant design not only mitigates the environmental impact, but also reduces investment costs and contributes to the key factors mentioned. M. Pieper and P. Kamermann of thyssenkrupp Industrial Solutions discuss how, by using the right design, safety in ammonium nitrate plants can be easily achieved, while maintaining outstanding product quality.

A recent report from BloombergNEF (New Energy Foundation) looking ahead to 2050 argues that green hydrogen can be cheaper than natural gas. It finds that ‘green’ hydrogen from renewables should become cheaper than natural gas (on an energy-equivalent basis) by 2050 in 15 of the 28 markets modelled, assuming scale-up continues. These countries accounted for one-third of global GDP in 2019. In all of the markets BNEF modelled, ‘green’ hydrogen should also become cheaper than both ‘blue’ hydrogen (from fossil fuels with carbon capture and storage – CCS) and even ‘grey’ hydrogen from fossil fuels without CCS. The cost of producing ‘green’ hydrogen from renewable electricity should fall by up to 85% from today to 2050, the report predicts, leading to costs below $1/kg ($7.4/MMBtu) by 2050 in most markets. These costs are 13% lower than BNEF’s previous 2030 forecast and 17% lower than their previous 2050 forecast. Falling costs of solar photovoltaic (PV) electricity are the key driver behind the reduction; BNEF now believes that PV electricity will be 40% cheaper in 2050 than they had thought just two years ago, driven by more automatic manufacturing, less silicon and silver consumption, higher photovoltaic efficiency of solar cells, and greater yields using bifacial panels.

N. Clark, B. Avancini and V. Sturm of Clark Solutions discuss a novel technology, SAFEHX® , providing a new approach to the cooling of strong sulphuric acid. Prototype results are shown and indicate a safe and stable cost-effective technology. SAFEHX® can be extended to every heat exchanger system where corrosion, mixture risks, fouling, process liquid loss (or contamination) and temperature control are key concerns.

Calgary-based Pieridae Energy Ltd says that it has hired a new Chief Operating Officer as from April 5th. Darcy Reding is a professional engineer with 30 years of experience in small and medium-sized private and public upstream oil and gas companies, 20 years of that in leadership roles. Reding spent the last decade at NAL Resources as VP of Operations and VP Operations & Geoscience. Prior to NAL, Reding held technical and leadership roles with Norcen Energy, Northrock Resources, Samson Exploration and Enterra Energy Trust.

With declining ore grade feed to a metallurgical smelting process comes an increase in impurity load in the gas cleaning/acid process chain. K. Hasselwander, L. Skilling and C. Bartlett of Metso Outotec discuss a range of process solutions and how to maintain high productivity while keeping costs in check.

We highlight recent advances in ammonia and dust scrubbing systems for urea plants from Stamicarbon, thyssenkrupp Industrial Solutions and Toyo Engineering Corporation.

Nouryon is introducing a new anionic ‘gemini’ collector for phosphate flotation under the product name Phospholan G10. These novel dimeric reagents offer distinct performance advantages over conventional fatty acid collectors.

Prayon’s Hadrien Leruth and Marc Sonveaux highlight the latest phosphate production developments at the company – and share their experience of how innovative ideas are validated, industrialised and turned into commercially-viable technologies.

Newly-developed froth flotation equipment and reagents are improving selectivity and the grade and recovery of phosphate concentrates.

The year 2020 will be remembered as an uncertain, demanding and challenging year. When faced with a global pandemic, companies have adopted new approaches and remote inspection, monitoring and training using the latest digital tools has been key for the successful completion of projects. Stamicarbon, Casale and KBR share some of their experiences of the past year.
