Reclaiming phosphorus from sewage sludge ash holds great potential for the fertilizer industry – by helping to reduce dependency on global supply chains, ensuring resilience and even raising quality. But successful phosphorus recovery largely depends on the process used, as EasyMining’s Anna Lundbom, Sara Stiernström and Christian Kabbe explain.
INEOS says that it is aiming to forward its plans for a ‘net zero’ future for its Grangemouth site in Scotland by inviting major engineering design contractors to tender for the next stage of the design of a world scale carbon capture enabled hydrogen plant and associated infrastructure.
The CRU Nitrogen + Syngas Conference returns to Berlin for a live event from 28-30 March 2022. The conference will be run as a hybrid event giving participants the option to attend live in-person or online via the virtual platform.
As all industries come under pressure to decarbonise, are there ways to reduce the carbon footprint of sulphur recovery operations?
A detailed rain and wastewater concept is an important part of a urea plant to meet current stringent environmental standards. Wastewater can originate from the process reaction or from outside the process equipment. In order to optimise the wastewater system of a urea plant, both the amount and type of contamination need to be known. With this knowledge, non-contaminated rainwater as well as process drains can be kept separate as much as possible to minimise the amount of wastewater to be treated, saving costs and energy. Wastewater treatment concepts from thyssenkrupp Industrial Solutions and Toyo Engineering Corporation are described.
Nitrogen-rich wastewaters remain a major issue for fertilizer and other industries. Saipem’s new electrochemical technology, SPELL, is an important step towards the overall objective of zero industrial pollution. A complete engineering review of the technology, its alignment with all international applicable standards, and optimisation has now been concluded and the technology is ready for deployment for the removal of ammonium nitrogen from industrial waters and wastewaters. Saipem discusses the key features of SPELL and reports on the first two industrial references.
Fertilizer International presents a global round-up of current potash projects.
RSK and its subsidiary ADAS have developed a sustainable solution for the disposal of sulphur waste generated from a natural gas processing facility in Iraq. C. Teulon of RSK reports on the research that was carried out to test whether the waste sulphur from a biological sulphur removal process could be applied in agriculture to increase the quality and quantity of crops in Iraq.
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 latest developments in the recovery and commercialisation of fluorosilicic acid, rare earth elements (REEs) and uranium co-products associated with phosphoric acid production.
