MOPCO has selected thyssenkrupp Uhde to supply advanced technology for its Damietta ammonia-urea complex in Egypt.

Metso launches Cu POX leaching process for copper extraction industry - solution maximises copper recovery while reducing environmental impact

While there is still a considerable push for use of biomass waste as a lower carbon feedstock for chemical production via gasification to syngas, biological processes such as fermentation are increasingly gaining traction as an alternative.

Carbon Recycling International (CRI), which operates a geothermally powered green methanol plant at Svartsengi, 40km southwest of Reykjavik, had to evacuate its site in late November when a 3km fissure opened in the earth a few kilometres away and lava began spilling across adjacent land. Satellite photos of the area taken on November 24 show a large field of molten and cooled lava to the north, west, and south of Svartsengi, though the plant itself remained undamaged. CRI’s Iceland facility runs on CO2 , water, and renewable electricity from the Svartsengi geothermal power station. CRI says the low-carbon energy source allows it to produce 4,000 t/a of methanol with a greenhouse gas footprint just 10–20% that of conventional methanol.

Marcus Weber of Fluor discusses degassing units for large scale sulphur recovery units, evaluating the pros and cons of various available commercial technologies with the emphasis on mega size sulphur recovery units and focussing on how technology can lower degassing capex via economy of scale for new facilities or existing facilities undergoing expansion.

TOYO has recently introduced new proprietary urea technologies to its technology portfolio including a novel dust scrubbing system with integrated wet electrostatic precipitator (WESP) for ultimate clean-up of granulation or prilling exhaust air, to achieve urea dust emissions of less than 5 mg/Nm3 . Takuhiro Minato of Toyo Engineering Corporation explains how the new system works.

Based on 16 years of experience, Muhammad Nabeel Shakir of Fatima Fertilizer Company outlines a methodology to achieve optimum performance of the PGM catalyst and catchment system in nitric acid plants.

This year will be the 40th Sulphur – now Sulphur + Sulphuric Acid – Conference to be held. From its beginnings in Canada to this year’s meeting at the Hyatt Regency hotel in Barcelona, much has changed, but its mission – to be an essential annual forum for the global sulphur and acid community – remains the same.

Innovative catalyst systems from Heraeus and Łukasiewicz Research Network – New Chemical Syntheses Institute contribute to reach climate goals by reducing N2 O emissions during nitric acid production. Dr Uwe Jantsch and Jens Hesse of Heraeus Precious Metals report on the process performance results achieved for N2 O reduction in nitric acid production using FTC gauze systems and iron oxide based secondary catalysts.
