Correct fertilizer usage at each crop stage can helps avocado growers improve their yield, quality and profitability. ICL’s Mateo Martinez and Alveiro Salamanca-Jimenez explain how growers can supply crop nutrients to avocado trees, efficiently and effectively, using economically- and environmentally-sustainable principles.
With climate change looming there is an increased focus on reducing the environmental footprint of the production of fertilizers. The use of renewable energy/green hydrogen is one way to make the fertilizer industry more environmentally sustainable. In this article, Rene Dijkstra of Chemetics introduces the Green Fertilizer Complex. This practical solution integrates an oxygen-based sulphuric acid plant using the Chemetics’ patented CORE-SO2™ process with a green hydrogen and ammonia facility to deliver low cost, low emission, and carbon-free phosphate (MAP/DAP) and/or sulphate (AMS) based ammonia fertilizers.
As all industries come under pressure to decarbonise, are there ways to reduce the carbon footprint of sulphur recovery operations?
Ricardo L. Sepulveda of PegasusTSI reviews options to decrease the CO2 footprint of a fertilizer industrial complex and illustrates the technical and economic feasibility of utilising clean energy from a sulphuric acid plant in a fertilizer complex to produce green hydrogen, which in turn can be used to produce green methanol or green ammonia.
A new cost-effective alternative sulphur technology, providing a simple and robust process to achieve an overall sulphur recovery efficiency of 99.9+% is being developed by Saudi Aramco. J. P. O’Connell and I.A. Alami of Saudi Aramco discuss the new technology, its benefits and current stage of development.
Sarah Fedorchuk, Mosaic’s vice president, government and public affairs, North America, explains how recycling phosphogypsum from Florida can help America compete globally.
State-of-the art technologies offered by thyssenkrupp, Casale and Stamicarbon are helping make nitrates production more secure and sustainable.
Decreasing the carbon intensity of sulphur recovery is one of the many actions that operators can take to help meet their climate ambitions. It is also becoming increasingly rewarding financially because of the rising cost of carbon emissions. In this article, G. Kidambi of Shell Projects & Technology demonstrates the potential to cut the carbon intensity of tail gas treating units by more than 50% through swapping to the latest SCOT ULTRA amine solvent and catalyst technologies.
Catalytic converters are the heart and hub of sulphuric acid plants. Converter replacement of equipment that has come to the end of its life is an opportunity to make improvements to the performance, productivity, reliability, durability and plant emissions. NORAM discusses design and project execution considerations for SO2 catalytic converter replacement and Chemetics considers the challenges and opportunities of converter retrofits.
Conventional fertilizers can be transformed into enhanced efficiency fertilizers (EEFs) using coating agents and inhibitors. Greater use of EEFs, by preventing nutrient losses and avoiding excess nutrient supply, can help global agriculture become more sustainable, as Urvi Mathur of Neelam Aqua explains.
