Mathijs Sijpkes, Nuria Pascual Vasco and Jan Hermans of Sulphurnet discuss the importance of a whole life cycle cost analysis at the conceptual design phase when making investment decisions about new sulphur processing facilities.
CO2 emission abatement strategies have become increasingly important as the world strives to combat global climate change. Mahin Rameshni and Stephen Santo of Rameshni & Associates Technology & Engineering (RATE USA) discuss carbon capture options available for sulphur recovery units.
M. Rameshni and S. Santo of Rameshni & Associated Technology & Engineering (RATE USA) report on advanced catalysts for increasing the sulphur recovery efficiency of new and existing sulphur recovery units to meet stricter environmental regulations.
The refurbishment and modernisation of fertilizer plants offers the opportunity to reduce operating costs, raise production capacity, improve energy efficiency and cut emissions.
Sulphur is becoming an increasingly vital crop nutrient, due to a combination of lower sulphur deposition from the atmosphere, the increasing prevalence of high-analysis fertilizers and higher cropping intensity.
Saipem, Stamicarbon, Toyo Engineering Corporation and KBR showcase recent projects and latest technology for urea and nitric acid plants.
Stamicarbon offers advanced scrubbing technologies for fertilizer granulation plants and prilling towers. This article describes the technology and experience with the second operational MMV scrubber, which is installed at the Dakota Gasification Company’s (DGC) urea granulation plant, and highlights the successful pilot test with its JV scrubbing technology.
China’s private sector Shenghong Petrochemical refining complex is targeting a startup in late November, following the receipt of its first cargo of crude in October. The greenfield refining complex in the eastern Lianyungang petrochemical zone has a capacity of 16 million t/a, including a 320,000 bbl/d crude unit – the largest single stream CDU in China – and a 76,000 bbl/d naphtha reformer. Product capacities include 56,000 bbl/d of gasoline, 41,000 bbl/d of diesel and 32,000 bbl/d of jet fuel. Construction began in mid-2019, delayed from 2018 by late approval of its environmental impact assessment, but has been achieved within two months of the scheduled completion date in spite of the coronavirus pandemic. Shenghong Petrochemical is owned by Eastern Shenghong, a producer of petrochemical products and chemical fibres.
More than 230 delegates from 45 countries participated in CRU’s Sustainable Fertilizer Production Technology Forum, 20-23 September 2021. To highlight this successful virtual event, we report on keynote and selected technical presentations.
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.
