Tightening regulations and growing global competition are increasing the pressure felt by sulphuric acid plant operators to reduce emissions and improve energy output. Conservation of energy is a continuous focus for operators, and environmental communities have grown more vocal in their desire for greater emissions oversight. In this article, DuPont Clean Technologies examines simple, tried, and true tactics, as well as new products and designs that can be incorporated into existing plants to address operating efficiency and emissions and to help to prolong the life of the plant.

Dealing with sulphur dust is an operational challenge for sulphur forming plants and sulphur storage and handling facilities.

Corrosion is one of the most critical aspects regarding sulphuric acid plant lifespan. One important cause of corrosion in sulphuric acid plants is acid condensation from the process gas due to inadequate drying. E. Almeida, B. Ferraro, N. Clark, V. Machida and V. Sturm of Clark Solutions discuss this problem and how it can be avoided with proper tower and internals design.

Comprimo has recently launched two new solutions to make the most of existing data and to improve customer’s operations and customer knowhow: Comprimo Insight – an intelligent sulphur plant dashboard, and Comprimo Immerse – a dynamic sulphur plant simulator. In this article, Comprimo goes into the details of how Comprimo Insight and Comprimo Immerse are being implemented for its customers.

A holistic understanding of the phosphate milling process is necessary, says Ian Hancock of Bradley Pulverizer. This ensures maximum plant uptime, the highest process efficiencies, and ultimately guarantees profitability.

The crushing and grinding of mined phosphate rock and potash ore is a vital preparatory step for subsequent beneficiation and chemical processing. Although often overlooked, the efficiency of downstream P & K fertilizer production is heavily reliant on successful particle size reduction upstream.

We highlight the large-scale nitrogen projects that are currently under development across the globe – with a focus on ammonia and urea technology licensors and engineering contractors.

The European Union is seeking to create a climate-neutral and circular economy through its flagship Green Deal policy. The fertilizer industry can support these objectives by adopting inhibitor treatment technology (ITT) and controlled-release fertilizers (CRFs) based on biodegradable polymers. These two innovations have a vital role to play in improving nitrogen use efficiency and the shift towards more sustainable resource use, says Dr Matthias Potthoff of thyssenkrupp Fertilizer Technology.

A selection of innovative products and technologies that have recently been brought to market.

T. Hentrich and B. Nowak of VDM Metals provide an overview of the development of VDM® Alloy 699 XA, a new generation, metal dusting resistant alloy, available in a wide range of product forms, for demanding applications in the chemical process industry.
