Johnson Matthey and MyRechemical have formed an alliance to commercially develop waste to methanol technology. In this article, two different approaches to waste disposal and chemical production are analysed: a post combustion scenario with waste incineration and hydrogenation of the CO2 recovered from flue gas to produce methanol, and a precombustion approach with waste gasification followed by conversion of synthesis gas into methanol.
By utilising state-of-the-art technologies, nitric acid and ammonium nitrate producers are able to reduce the environmental impact of their production plants and make a key contribution to climate protection.
India’s power and renewable energy minister RK Singh has placed draft plans before the cabinet for the country’s refining and fertilizer sectors to switch to renewable ‘green’ hydrogen feeds. Other energy intensive sectors such as steel and transport are likely to follow. The policy suggests that refiners must have 10% of their hydrogen consumption generated from renewable electricity by the end of financial year 2023-24, rising to 25% by 2030. The comparable figures for ammonia/urea production are 5% and 20%, respectively. India is pursuing some of the world’s most ambitious renewable energy targets of 175 GW of renewable energy capacity by the end of 2022 and 450 GW by 2030.
During this time of disruption, keeping connected and informed has never been more important. While the in-person events the industry usually relies on are not possible, CRU’s virtual Sustainable Fertilizer Production Technology Forum, 20-23 September, offers exceptional information sharing and networking opportunities.
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.
