As urea plants grow in capacity, so does the need for finishing technologies with higher capacities. Barbara Cucchiella , senior process engineer at Stamicarbon, describes how her team has risen to the challenge of the global trend for larger granulation plants.
The US Environmental Protection Agency (EPA) and the US Department of Agriculture (USDA) have announced the ‘Next Gen Fertilizer Challenge’, a joint EPA-USDA partnership and competition to advance agricultural sustainability in the United States. The competition includes two challenges that seek proposals for new and existing fertilizer technologies to maintain or improve crop yields while reducing the impacts of fertilizers on the environment.
Recent protests in Belarus have triggered a wave of share price volatility, London’s Financial Times reported on 18th August.
K. Hanlon Kinsberg and J. Lewis of Comprimo review the main approaches for mercaptan removal in gas processing plants, based on past project experience and generally accepted industry practice.
Reg Adams of pigments and titanium dioxide consultancy Artikol reviews the demand for sulphuric acid in the manufacture of TiO2 , and the prospects for consumption over the next few years.
Haldor Topsoe and Comprimo® have announced a global strategic alliance to jointly license the TopClaus sulphur removal and recovery technology. TopClaus combines Topsoe’s energy efficient wet sulphuric acid (WSA) process with the industry-standard Claus process, enabling plant operators to handle acid gases and achieve sulphur removal efficiencies of above 99.9%. The Claus part of the unit recovers elemental sulphur from acid gases, and the tail gases from the Claus unit are then treated in the WSA unit, where the remaining sulphur compounds are converted into sulphuric acid.
DuPont Clean Technologies has announced the successful startup and performance test of a 300,000 t/a STRATCO® alkylation unit licensed at the Hengli Petrochemical Company’s new refinery complex on Changxing Island in the Harbour Industrial Zone, China. The new alkylation unit enables Hengli to produce high-quality alkylate from a 100% isobutylene feed stream, catalysed by sulphuric acid. This first-of-a-kind unit was developed through DuPont research into the best ways to maximise product octane and minimise end point with this feedstock. Hengli had awarded DuPont the contract for the new alkylation unit as well as a MECS® sulphuric acid regeneration unit in 2015.
Fugitive dust emissions during the handling and storage of formed sulphur can result in negative environmental impacts and under specific conditions result in an explosion hazard. Enersul has developed a dust suppression system specifically targeted at controlling sulphur dust particles. The Enersul SafeFoam Transfer System (STS) reduces sulphur fines at critical transfer points throughout any sulphur handling system, resulting in a significantly safer and more environmentally friendly sulphur handling system.
IPCO provides an update on its latest activities, with flexible processes enabling IPCO’s project for the first drum granulation plant in Europe to remain on track despite unprecedented Covid-19 restrictions.
