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.

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.

‘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.

thyssenkrupp Industrial Solutions (tkIS) offers and builds Power-to-X plants and can provide all processes of the value chain, from water electrolysis and CO2 recovery to green ammonia, green methanol and green SNG. Renewable methanol production, which combines the application of carbon capture and utilisation with chemical energy storage, is a particularly promising sustainable solution.

The different flame velocities of reactants in the combustion space of a secondary reformer have a significant impact on the gas inlet temperature of the catalyst and the methane conversion in front of the catalyst. Based on this fact, Hanno Tautz Engineering introduces an alternative secondary reformer design. Compared with the state-of-the-art-technology, the alternative design shows advantages for hydrogen production efficiency and product capacity.

Cryogenic purge gas recovery units are very tolerant to increased flow from ammonia plant debottlenecking, especially the cryogenic cold box section. However, overload of the dehydration system upstream of the cold box can lead to fouling, loss of hydrogen recovery performance and the need for costly shutdown and thaw. Awareness of key plant parameters and some simple precautions can avoid such problems. A. J. Finn and T. R. Tomlinson of Costain provide some guidance.
