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.
