The coronavirus outbreak necessitated a ‘virtual’ CRU Sulphur + Sulphuric Acid conference last year, held in November 2020.

Brimstone STS Ltd. today announced a new partnership with Sulphur Recovery Engineering Inc (SRE). The two companies say that this collaboration will bring together decades of experience and the latest technology in support of the sulphur recovery and gas treating industry worldwide.

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.

China’s copper industry is facing difficulties caused by the coronavirus outbreak in the country. Prolonged factory closures, particularly in Hubei province, at the centre of the outbreak, as well as neighbouring Guangdong and Zhejiang, also badly affected, have caused a slump in demand for copper domestically as copper fabricators remain on extended closure. However, smelters have resisted cutting production. Daye Nonferrous, based in Huangshi at the centre of coronavirus outbreak, continues to operate at 80% of its 600,000 t/a capacity for 1Q 2020, according to the company, in spite of quarantine and transport restrictions which have reduced truck shipments to the smelter – Daye is reportedly still able to receive copper concentrate shipments via the Yangtze River to Huangshi port.

CRU’s Sulphur + Sulphuric Acid 2019 conference was held in Houston last November.

The Ma’aden Wa’ad Al Shamal Phosphate Company (MWSPC) has signed a service agreement for a period of three years with DuPont Clean Technologies for its sulphuric acid plant at Sirhan. The service programme will include activity testing of catalyst samples, evaluation of catalyst performance, plant optimisation, troubleshooting and management of catalyst replacement. DuPont says that it will also track plant performance and assess its overall health using pre-agreed metrics and its proprietary PeGASyS™ gas chromatography system, which can be used to detect possible leaks in gas-gas heat exchangers, identify SO2 gas bypassing and measure overall plant conversion in order to optimise plant operation, reduce SO 2 emissions, increase production and improve converter performance.
