    Sulphuric Acid News Roundup

    Copper major Freeport-McMoRan is reportedly on verge of finalising a $2.8 billion deal with China’s Tsingshan to build a copper smelter in Weda Bay, Indonesia. The Indonesian government said that the companies were aiming to conclude negotiations by the end of March. It also said that most of the financing will be borne by Tsingshan, with Freeport possibly only needing to provide funding for 7.5% of the total project cost. The smelter would have a copper concentrate input capacity of 2.4 million t/a.

    Building on its long experience and leading position within global ammonia production, logistics and trade, Yara says that it aims to capture opportunities in green shipping, agriculture and industrial applications; a market expected to grow by 60% over the next two decades. A major first step includes plans to fully electrify its ammonia plant at Porsgrunn, Norway, with the potential to cut 800,000 t/a of CO 2 , equivalent to the emissions from 300,000 passenger cars.

    Norilsk Nickel has finally closed down its nickel smelting operation at Nikel in Russia’s Murmansk region; the company’s oldest still operating production facility. The shutdown is part of the company’s environmental programme, which aims to significantly reduce its environmental impact at all production sites. The Nikel closure will eliminate SO2 emissions in the cross-border area with Norway, which had become a major bone of contention with the Norwegian government. Norilsk aims to reduce SO2 emissions at Kola by 50% by the end of 2020 and 85% by the end of 2021, and is modernising its production in Monchegorsk, including the construction of new state-of-the-art facilities.

    Construction work has begun on a new hydrocracking complex for the Assiut refinery in Egypt, in the central Nile valley, according to TechnipFMC plc, who won the $1 billion engineering, procurement, and construction (EPC) contract for the project. The contract involves construction of new processing units including a vacuum distillation unit, a diesel hydrocracking unit, a delayed coker unit, a distillate hydrotreating unit and a hydrogen production unit which will use TechnipFMC’s proprietary steam reforming technology.

    Materials for pumps, valves, and piping in sulphuric acid service

    Several highly corrosion resistant materials are available today for use in handling process fluids encountered in the production of concentrated sulphuric acid. These alloys, properly selected for the operating conditions, provide the benefits of long operating life under harsh operating conditions extending the period of uninterrupted production cycles and lowering the incidence of catastrophic equipment failure. In this article, M. J. Cooke of Weir Minerals discusses materials of construction for pumps, valves and piping used in the production of sulphuric acid.
