Daniel R. Egger of Sulzer Chemtech Ltd discusses mist elimination challenges in strong sulphuric acid applications and presents the unique Sulzer KnitMesh XCOAT™ mist eliminator as an ideal solution for corrosive services such as in sulphuric acid drying towers.
Sulphur is a relatively safe and inert solid. However, it has a number of unique physical and chemical properties which can give rise to hazards, particularly during transport and handling.
A move towards so-called ‘sustainable aviation fuels’ (SAF) could see refineries having to recast their operations. What might this mean for sulphur production?
Meena Chauhan, Head of Sulphur and Sulphuric Acid Research, Argus Media, assesses price trends and the market outlook for sulphur.
Global demand for rare earth metals is increasing, particularly for electric vehicle batteries and renewable energy devices, potentially leading to increased use of sulphuric acid in their extraction.
Inshan S. Mohammed of Sulfur Recovery Engineering shares lessons learned from a recent SRU shutdown assistance programme involving an error with the tags used within the BMS system installed on a direct-fired reheater.
A large portion of the oil reserves of Canada and Venezuela exist as oil sands. By the mid-2000s, production from these sources had topped 5.5 million bbl/d. But with Venezuela’s economic implosion and increasing environmental scrutiny of oil sands production, what is the future for this high sulphur fuel source?
Marco van Son and Frank Bela of Comprimo share lessons learned from SRU war stories, including: inadvertent NH3 destruction in an oxidising atmosphere, rich amine emulsion, SWS fixed valve trays, H2 spiking of SRU feed, rich amine flash drum early warning, V-ball fuel gas safety shutoff valves, TGTU methyl mercaptan, and commissioning and Murphy’s Law.
While most sulphuric acid demand for phosphates is based on the production of phosphate fertilizer, non-fertilizer sources of demand such as animal feed and industrial processes additionally represent a relatively small but growing sector of the market.
The purpose of this article is to emphasise the lessons learned by ADNOC Sour Gas in the material upgrading of the Shah sulphur granulation plant due to severe corrosion of the aluminium components. The sulphur granulation plant was commissioned in 2015 and consists of a total of 12 granulating systems used for solidifying and granulating the liquid sulphur. The study focused on the corroded areas, namely the GX plenum chambers, the lower section of the granulator exhaust stack, the scrubber inlet and the discharge ducting.
