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.

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.

Demand for oil in developed countries was already falling before the coronavirus outbreak, and consumption growth is slowing in the developing world. Peak oil demand may arrive in the next decade. Coupled with more reinjection of sour gas rather than sulphur extraction, could we be seeing falling elemental sulphur production in a decade or so?

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.

Illinois-headquartered CF Industries has made a long-term commitment to low-carbon ammonia production and net-zero emissions.

Johnson Matthey and KBR have announced that they have signed a global strategic alliance agreement to license a new ammonia-methanol co-production process that combines the companies’ ammonia and methanol process technologies. The companies say that the co-production process makes the most of synergies between the two technologies, maximising savings while offering the highest levels of safety, flexibility and reliability.

The US Environmental Protection Agency (EPA) and the US Department of Agriculture (USDA) have announced the ‘Next Gen Fertilizer Challenge’, a joint EPA-USDA partnership and competition to advance agricultural sustainability in the United States. The competition includes two challenges that seek proposals for new and existing fertilizer technologies to maintain or improve crop yields while reducing the impacts of fertilizers on the environment.

Every five years since 1955, the Chinese government has prepared its ‘Five Year Plan’ for the country’s economy over the coming half decade. This year, the 14th Five Year Plan is being drafted, and given the influence of the Chinese economy over the global chemical sector, its conclusions will be eagerly awaited.

Undegassed molten sulphur can contain several hundred ppmw H2 S. If the headspace in the storage tank is stagnant, the H2 S can accumulate in the vapour space above undegassed liquid sulphur to dangerous levels. Sweeping and blanketing systems are commonly applied to manage the explosion risk in the headspace of molten sulphur storage tanks. D. J. Sachde , C. M. Beitler , K. E. McIntush , and K. S. Fisher of Trimeric Corporation review these approaches, outlining the benefits and limitations, design considerations, and industry experience/guidance for each approach. Calculation methods for natural draft flow of sweep air are also presented.

For the protection of nozzles in sulphur forming plants it is important to prevent larger particles from entering the forming machinery and possibly blocking the nozzles. In normal operation, pipeline strainers are used. Sulphurnet has designed a new system which is suitable for continuous or batch operations and has lower maintenance costs. J. Hermans of Sulphurnet introduces the self-cleaning sulphur strainer.
