Fertilizer International presents a global round-up of phosphate rock, phosphoric acid and finished phosphates projects.

Newly-developed froth flotation equipment and reagents are improving selectivity and the grade and recovery of phosphate concentrates.

After many years of slow decline, Canadian sulphur exports have begun to rise slightly, but dwindling US markets are seeing a move towards more sulphur forming to expand export opportunities.

Although 2019 had been a volatile year for acid markets, with shutdowns disrupting supply, the coronavirus outbreak wrought even more havoc in 2020, across both supply and demand.

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.

A look at the major factors influencing the sulphur market around the world.

When producing from shale reservoirs, technologies such as horizontal drilling and hydraulic fracturing have been used successfully to access hydrocarbons that otherwise could not be. A less publicised issue in producing from certain hot shale gas reservoirs (T > 100°C) is the presence of H2 S and organo-sulphur compounds in the production fluids. In trying to understand the non-biogenic sources of H2 S, Alberta Sulphur Research Ltd has been involved in studying the decomposition of chemicals used in hydraulic fracturing when exposed to high temperature and high pressure.R.A. Marriott, J.J. Marrugo-Hernandez and R. Prinsloo of ASRL discuss the findings of the study.

A consortium of Chinese buyers has agreed the first potash contract with the Belarusian Potash Company (BPC) since September 2018.

Evaporation and crystallisation are widely used throughout the fertilizer industry. Major applications and the types of equipment used are reviewed by Laurent Palierne and Norbert Strieder of GEA Group.

Nutrien has temporarily shut down one of the four ammonia plants at its Trinidad production site.
