In its most recent interim report, published on August 15, renewable energy developer Ørsted said that it was abandoning the FlagshipONE renewable methanol project because the anticipated market for green methanol as a marine fuel had not materialised as quickly as expected. The strategic decision comes nearly two years after final investment decision (FID) on the project.
Part 1 of this series on stripper efficiency issues provided a brief history of the CO₂ stripping process and discussed how the invention of the HP CO₂ scrubber back in the 1960s revolutionised urea technology. In part 2 we take a look at how high liquid load can affect stripper efficiency.
Innovative catalyst systems from Heraeus and Łukasiewicz Research Network – New Chemical Syntheses Institute contribute to reach climate goals by reducing N2 O emissions during nitric acid production. Dr Uwe Jantsch and Jens Hesse of Heraeus Precious Metals report on the process performance results achieved for N2 O reduction in nitric acid production using FTC gauze systems and iron oxide based secondary catalysts.
A round-up of current and proposed projects involving non-nitrogen synthesis gas derivatives, including methanol, synthetic/substitute natural gas (SNG) and gas- and coal to liquids (GTL/CTL) plants.
A look at the safety challenges that face developers of ammonia-powered shipping vessels before it can become used more widely as a low carbon fuel.
Casale, Saipem, Stamicarbon & Toyo Engineering Corporation showcase a selection of innovative technologies that have recently been brought to the market.
Ammonia markets were quiet in June, though both CF Industries and Grupa Azoty were reported to be looking for July tonnes and the enquiry will test how tight the market is going forward. Algeria has traded in the $400-405/t f.o.b. range, suggesting c.fr values in Europe might be slightly higher at $450-460/t c.fr. Supply from Algeria has been and continues to be somewhat restricted because of constraints caused by the hot weather. Gas supply however is easing in Egypt and further ammonia exports should emerge shortly.
Prices in the Eastern Hemisphere, whilst still flat-to-firm, do not appear as supported as they have been over the past month, whilst indexes. There are still no signs of softening in the Far East although demand remains underwhelming and supply improving. While production in Indonesia is said to be back up and running, traders do not expect any spot cargo to emerge in July other than possibly some small part cargoes. August could see spot offers.
Pres-Vac Engineering's innovative high-velocity methanol valves offers shipbuilders unique options in creating more efficient and compliant dual-fuel systems.
The reliability of primary reformers is a key issue for syngas plants. Quest Integrity describes the damage mechanisms and material limitations that impact the reliability of reformer outlet systems and the improvements that may be implemented.
