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.

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.

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

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

Three large-scale phosphoric acid plants constructed as part of the world-class Umm Wu’al project in Saudi Arabia are now fully operational. James Byrd of Worley (formerly Jacobs ECR) describes the execution of the project from basic engineering through to plant performance tests.

The DA-HF phosphoric acid process has been successfully implemented at Grupa Azoty’s Police fertilizer production plant in Poland, as part of a revamp of the site’s existing DH plant. Sébastien Havelange and Alexandre Wavreille of Prayon Technologies outline the performance improvements achieved by this first-of-its-kind plant.
