Considering the current shift to produce biofuels instead of conventional oil products, M. van Son of Comprimo discusses the impact that this may have on the ability to process the sour water acid gas streams produced in existing or new sour water strippers.
Major fertilizer industry players such as Stamicarbon, Nutrien and CF Industries are ramping up investment in ‘green’ and ‘blue’ fertilizer production. Consequently, low-carbon production technologies are being scaled-up and deployed commercially.
Buss ChemTech AG offers the international phosphate industry a robust solution to create added-value products from fluorosilicic acid (FSA). Thomas Dahlke, the head of the company’s process engineering department, and Emre Sen, sales manager for fluorine technologies, explain how this can be done in a sustainable manner.
Johnson Matthey and MyRechemical have formed an alliance to commercially develop waste to methanol technology. In this article, two different approaches to waste disposal and chemical production are analysed: a post combustion scenario with waste incineration and hydrogenation of the CO2 recovered from flue gas to produce methanol, and a precombustion approach with waste gasification followed by conversion of synthesis gas into methanol.
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.
Plans to decarbonise power production and shipping are leading to increasing interest in using ammonia as a fuel, but technical and economic barriers still remain to be overcome.
M. Østberg and M. Rautenbach of Haldor Topsoe describe ReShift ™ technology, a new high temperature CO 2 reforming process, where preheated CO 2 is added directly downstream of a main reformer and then equilibrated in an adiabatic reactor. This new technology makes use of the high temperature of the reformer effluent to circumvent carbon formation, while at the same time maintaining an overall minimum steam to hydrocarbon carbon ratio, depending on process specific conditions. An increase in the amount of CO 2 added to the process will result in an increased fraction of CO in the produced synthesis gas. Synthesis gas with H 2 /CO ratios in the range 0.5-3 can be produced. These CO-rich gases are typically utilised in the production of functional chemicals and synthetic fuels.
Philippe Malsan of Technip Energies explains how high recovery Diplo phosphoric acid technology can generate phosphogypsum suitable for industrial reuse. Industrial cases studies for Senegal and Austria show how phosphogypsum from this process has been successfully recycled on a large scale for cement, plaster and other end uses.
Reducing the carbon footprint in the synthesis of chemicals is a new global challenge as the world works towards providing sustainable products designed to minimise their environmental impacts throughout their whole lifecycle. This article looks at the role of blue technologies as part of a roadmap towards the decarbonisation of fuels and chemicals.
The economic conversion of phosphogypsum waste into a valuable product has been pursued for decades. Results of intensive research by thyssenkrupp Industrial Solutions (tkIS) in this area are presented by Peter Stockhoff, Dirk Koester, Stefan Helmle and Carsten Fabian. The approach developed by tkIS shows great potential as a controlled treatment process for phosphogypsum.
