Plans to decarbonise power production and shipping are leading to increasing interest in using ammonia as a fuel, but technical and economic barriers still remain to be overcome.

To comply with stricter stack emission obligations, industries are required to recover more heat from flue gas and to clean it before it can be discharged into the atmosphere. J. Kitzhofer of APEX Group discusses the challenges and limitations of the majority of current heat recovery systems and reports on a new family of acid resistant tubular and plate-type heat exchangers developed by APEX Group that overcomes these problems. The new heat exchangers are resistant to dew point corrosion. The heat transfer elements are constructed from an acid resistant polymer composite with high thermal conductivity, allowing the design of new trouble-free heat recovery systems and the upgrade of existing systems to meet heat recovery and stack emission targets.

Metal dusting corrosion damage on steam reformers is no longer a major issue in modern methane steam reformer units. Nevertheless, failures related to metal dusting corrosion attack still take place in some specific designs and configurations that are more prone to experience this damage. Poor maintenance or deterioration of insulation components on transition areas might expose metallic surfaces to metal dusting attack. In this article, Dr P. Cardín and P. Imízcoz of Schmidt+Clemens Group describe different case studies, where the end users benefited from the experience of a collaboration to address potential risks and improve plant reliability against metal dusting corrosion damage.

CF Industries has signed an agreement with thyssenkrupp to develop a commercial-scale green ammonia project at its Donaldsonville production complex in Louisiana.

The Chemical & Process Technologies business unit of thyssenkrupp Industrial Solutions is celebrating a milestone in 2021. It is one hundred years since engineer and entrepreneur Friedrich Uhde founded his own plant engineering company in a barn at his parents-in-law’s farm in Dortmund-Bövinghausen on April 6th, 1921. Now, in this centenary year, the origins of the firm are to become visible in its name again: thyssenkrupp is changing the business unit’s name to thyssenkrupp Uhde.

A recent report from BloombergNEF (New Energy Foundation) looking ahead to 2050 argues that green hydrogen can be cheaper than natural gas. It finds that ‘green’ hydrogen from renewables should become cheaper than natural gas (on an energy-equivalent basis) by 2050 in 15 of the 28 markets modelled, assuming scale-up continues. These countries accounted for one-third of global GDP in 2019. In all of the markets BNEF modelled, ‘green’ hydrogen should also become cheaper than both ‘blue’ hydrogen (from fossil fuels with carbon capture and storage – CCS) and even ‘grey’ hydrogen from fossil fuels without CCS. The cost of producing ‘green’ hydrogen from renewable electricity should fall by up to 85% from today to 2050, the report predicts, leading to costs below $1/kg ($7.4/MMBtu) by 2050 in most markets. These costs are 13% lower than BNEF’s previous 2030 forecast and 17% lower than their previous 2050 forecast. Falling costs of solar photovoltaic (PV) electricity are the key driver behind the reduction; BNEF now believes that PV electricity will be 40% cheaper in 2050 than they had thought just two years ago, driven by more automatic manufacturing, less silicon and silver consumption, higher photovoltaic efficiency of solar cells, and greater yields using bifacial panels.

Reducing the carbon footprint in the synthesis of chemicals is a new global challenge as the world works towards providing sustainable products designed to minimise their environmental impacts throughout their whole lifecycle. This article looks at the role of blue technologies as part of a roadmap towards the decarbonisation of fuels and chemicals.

Because of the ongoing pandemic, this year’s CRU Nitrogen + Syngas conference was held as a ‘virtual’ event, in early March 2021.

Georgy Eliseev , Principal Analyst at Fertecon for IHS Markit, looks at the medium to long term outlook for both ‘green’ and ‘blue’ ammonia production.

The profound demand shock caused by Covid-related lockdowns has had a major impact upon the refining industry. Run rates have been at low levels in North America and Europe, and a new wave of rationalisation is under way, at the same time that capacity continues to grow in Asia. Will this spur diversification into petrochemicals and low carbon options for Atlantic basin refiners?
