‘Green’ methanol means many things to different people. It encompasses low carbon emissions methanol manufacture at scale, recovery of material through waste gasification and conversion to methanol and power to liquid (e-fuel) methanol via electrochemistry and sometimes a combination of all of the above. Each route has a place in reducing the overall carbon footprint of production and subsequent use of methanol, driven by both governmental incentives or societal demand. In this article Andrew Fenwick of Johnson Matthey reviews the various routes to manufacture.

Floor prices in nitrogen markets are set by marginal producers high on the cost curve, usually using higher cost feedstocks. Recently, lower coal prices in China and the cost of imported LNG have begun to change the dynamic between producers on the margins.

Haldor Topsoe and Sasol have announced that they have entered into a collaboration agreement to jointly license their GTL technologies. For many years, the two companies have worked together on numerous GTL projects and technologies, and Topsoe’s Syn-COR™ syngas generation technology and Sasol’s Fischer-Tropsch technologies have been licensed for several world-scale GTL ventures. Under the new collaboration agreement, the companies will continue to offer these core technologies, but will now also provide Topsoe’s hydroprocessing and hydrogen technologies. This gives potential customers access to a single-point licensing offering that covers the entire value chain from gas feed to liquid fuels. As single-point licensors, Sasol and Topsoe will offer customers all necessary technology licenses for a complete GTL solution and in addition provide basic engineering, catalysts, and hardware.

At the time of writing this editorial, the World Economic Forum was having its usual annual meeting in the Swiss resort of Davos. Prior to this year’s meeting, as usual the WEF had produced its annual Global Risks Report to serve as a talking point for the meeting. While some of the risks were as usual political and economic, from proliferation of weapons of mass destruction and the “retreat from multilateralism” to growing inequalities of wealth in the developed world and “domestic political polarisation”, for the first time in the organisation’s history, the top five global risks in the report ranked by likeliness – which looks at potential global pitfalls over the next 10 years – were environmental. Perhaps with the pictures of Australia’s bush fire season fresh in their minds, the 750 experts ranked extreme weather events as the most likely, but climate change, biodiversity loss and sustainability in agriculture all ranked highly.

The increased severity of operating conditions in modern steam methane reformers requires catalysts with high catalyst activity and good mechanical stability to avoid premature replacements or unplanned shutdowns. F. Morales Cano, M. Stenseng and M. Feddersen of Haldor Topsoe describe a new catalyst formulation with a very homogenous and stable carrier material delivering the high activity and high mechanical strength required for long time operation.

Jerry d’Aquin of ConSul Inc. looks at the impact of falling sulphur prices on the US market.

Sulphuric acid plant operators juggle multiple issues trying to keep their plants running efficiently and reliably. With the revolutionary ClearView™ process health monitoring solution, as well the DynSOx™ software for simulating dynamic operation, Haldor Topsoe strives to bring digital services with real and tangible operational benefits to the sulphuric acid industry. P. Szafran and M. Granroth discuss how together these digital services can help acid plant operators meet their daily targets.

How the processed phosphates market develops over the coming months will be a major factor for the short term outlook for sulphur trends. Improvement is anticipated in the phosphates market from around mid-2020 which may help to support sulphur demand and in turn pricing.

After a poor 2019, when global demand contracted by nearly 2.5%, phosphate markets are expected to rebound in 2020. Saudi Arabia and Morocco dominate new capacity additions while India and Brazil continue to be the key importers. US and Chinese production is in slow decline, meanwhile.

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.
