Methanex has said that, in light of the uncertainty in the global economy from the Covid-19 pandemic, it will defer approximately $500 million of previously announced capital spending on its $1.4 billion Geismar 3 methanol project for up to 18 months. Geismar 3, which is intended to eventually produce 1.8 million t/a of methanol, will be placed on temporary “care and maintenance” for up to 18 months, enabling the company to complete the project when market conditions improve. Methanex says it will spend $100 million in Q1 2020 and a further $200 million from April 1, 2020 to September 30, 2021 on the project, the majority of which is spending that occurred or was committed during Q1 2020. This is approximately $500 million lower than the $800 million that was expected to be spent over that same period. Construction activity and procurement of non-critical equipment and bulk materials will be suspended until market conditions allow the Geismar 3 project to restart.

Imagine an industry that only uses carbon-free fuels and does not have any carbon footprint. Assume this is feasible within a decade. Now wouldn’t that be an ambition worth pursuing? Duiker believes this is achievable. A. Lanser provides Duiker’s view on how its SCO technology can act as an enhancer for reducing industrial carbon footprint.

The devastating effects of the Covid-19 pandemic continue to be felt around the world. At time of writing, nearly 4 million cases have been recorded, and at least a quarter of a million people have died, with the suspicion of many more, either from accidental or deliberate undercounting. Figures for excess deaths above a normal seasonal baseline show that places such as Turkey, Ecuador and Indonesia have probably been far worse affected than the official statistics show. There are nevertheless finally hopeful signs that Europe, so far the worst affected region, is beginning to follow the pattern of East Asia and Oceania and that cases are falling. The infection also seems to have peaked in North America, though in the US there is a long tail of infections. Elsewhere, cases are still rising in countries such as Brazil and Mexico.

Applied Analytics discusses potential improvements made possible with data and analytical measurements fed into improved mathematical models to produce a more proactive approach to control and better performance of sulphur recovery units, AMETEK Process Instruments explains the benefits of feed forward control, SICK reports on reliable continuous emission monitoring systems and WIKA introduces a new purge-free system to measure refractory temperature in the Claus reaction furnace.

Kuwait is in the middle of a major overhaul and expansion of its refining capacity, as well as boosting LPG output and sour gas processing.

The Abu Dhabi National Oil Co. (ADNOC) has awarded two EPC contracts with a total value of more than $1.65 billion for the offshore Dalma sour gas development, 190 km northwest of Abu Dhabi city. Dalma is one of the fields in the offshore Ghasha ultra-sour gas concession, which ADNOC views as central to the UAE achieving self-sufficiency in domestic gas supplies.

The UK’s Department for Business, Energy and Industrial Strategy has awarded £28 million ($36 million) of government funding to five demonstration projects for low carbon hydrogen production, as part of a larger stimulus package to cut industrial carbon emissions. The projects targeted for funding include:

At the Nitrogen+Syngas Conference 2020, held in The Hague, Netherlands, Haldor Topsoe launched its new TITAN ™ series of steam reforming catalysts. The company says that the new series, which consists of the RC-67 TITAN and RK-500 TITAN catalysts, offers improved performance and longer catalyst lifetime thanks to the hibonite-rich composition. The addition of titanium promoters adds exceptional mechanical strength while a seven-hole cylindrical shape yields both a very low pressure drop and a high surface area. Pressure drop build-ups in syngas plants can cause unscheduled downtime and cost millions of dollars, while thermal instability during operation can lead to operational risk and reduce plant lifetime. Topsoe says that the catalysts can mitigate these risks, ensuring lower operating costs, increased profit margins, and reduced energy usage.

Hydrocarbon contamination of sour water streams feeding sour water strippers is a well-known challenge in the refining and gas processing industry. The source of this challenge is the formation of a stable oil emulsion in an aqueous phase that may contain both H 2 S and NH 3 . The typical approach to the problem involves large residence time tanks with the assumption that droplet settling will occur over a long enough time frame. In practice, droplet settling is very slow due to a variety of reasons, and as a result, operators encounter sour water heat exchanger fouling, stripper fouling, hydrocarbon excursions to sulphur recovery units along with other operating challenges. M. Thundyil, D. Seeger and E. McIntosh of Transcend Solutions present a case study of the TORSEP™ oil and solids removal system for contamination removal from a sour water feed stream. The case study illustrates the effect on heat exchanger fouling along with the effect of the variation of several system parameters on operating performance and economics.

Using case studies of a refinery amine unit and a sour water stripper (SWS), U. M. Sridhar of Three Ten Initiative Technologies LLP, N. A. Hatcher and R. H. Weiland of Optimized Gas Treating Inc. demonstrate the capabilities of a mechanistic, chemistry-based, truly predictive model for calculating corrosion rates for various amines and for sour water. At a time when asset integrity is much sought after, the utility of this fully predictive model is to prevent failures before they occur, rationally select materials of construction, enhance plant safety, and mitigate risk.
