Casale has developed a range of methanol-ammonia coproduction processes to match different requirements according to product capacity.

Industry focus on technologies to reduce the carbon intensity of ammonia and methanol production has been intensifying. In this article thyssenkrupp Uhde, Proton Ventures, Toyo Engineering Corporation, Stamicarbon, BD Energy Systems and KBR report on some of their latest technology developments towards decarbonisation.

Fischer-Tropsch technology has long offered alternative production routes to synthetic fuels, but has struggled to make a use case outside of some niche applications. Could the greening of the chemical industry offer another way forward for the technology?

Venkat Pattabathula, a member of the AIChE Ammonia Safety Committee, reports on the American Institute of Chemical Engineers’ Safety in Ammonia Plants and Related Facilities Symposium, held at the Hyatt Regency in Chicago, USA, on 11-15 September 2022.

Maersk has ordered six more 17,000 teu (twenty-foot equivalent unit) container ships capable of running on methanol from Hyundai Heavy Industries (HHI). The order brings Maersk’s total order book of dual-fuel vessels capable of running on methanol to 19. Maersk said the new ships will replace existing tonnage in its fleet when they’re delivered in 2025. When all 19 vessels on order join the fleet and replace older tonnage, CO2 savings will be around 2.3 million t/a, according to Maersk. Maersk has committed itself to renewable methanol as a pathway to zero emissions shipping. Its first vessels are due for delivery from Q1 2024. The company has also signed several green methanol fuel supply agreements and joined a partnership to create the first e-methanol plant in Southeast Asia. Maersk is also working with Japanese trading house Mitsui and the American Bureau of Shipping (ABS), to jointly conduct a detailed feasibility study of methanol bunkering logistics in Singapore.

Maire Tecnimont subsidiary MyRechemical has been awarded a basic engineering contract for a waste to methanol and hydrogen plant to be located in Empoli, Tuscany. The scope of work includes the basic engineering design of the plant and the provision of necessary documentation to start the plant’s public authorisation process with the Tuscany region. The basic engineering phase is expected to be completed by the end of 2022. Once completed, the plant will process 256,000 t/a of non-recyclable waste and will produce 125,000 t/a of methanol and 1,400 t/a of hydrogen. The plant will use MyRechemical’s chemical conversion technology which allows the recovery of waste that cannot be mechanically recycled, or other types of unsortable dry waste. The carbon and hydrogen in the waste are converted via gasification into synthesis gas, which is used to produce low-carbon methanol and hydrogen.

Maire Tecnimont’s innovation and licensing company Stamicarbon has been selected as the licensor for a urea project in sub-Saharan Africa, its first license in the region. Stamicarbon will deliver the process design package for the front-end engineering and design for a 4,000 t/d urea melt and granulation plant. The urea melt plant with a pool reactor will use Stamicarbon’s MP Flash design, a melt concept with improved energy efficiency, entailing a significant reduction of steam consumption. The minimal equipment items result in a significant reduction of the footprint and the overall capital cost of the plant. Less equipment also allows for a reduction in maintenance costs and OPEX savings.

A round-up of current and proposed projects involving non-nitrogen synthesis gas derivatives, including methanol, hydrogen, synthetic/substitute natural gas (SNG) and gas- and coal-to-liquids (GTL/CTL) plants.

A record rise in gas prices at the end of August triggered a spate of ammonia production curtailments across Europe. These included major shutdown announcements from CF Fertilisers UK, Grupa Azoty, Yara International and others.

Effective and efficient wastewater management is a vital task that is being aided by the introduction of new treatment technologies. The recovery of economically-valuable nutrients from wastewaters is another priority.
