NextChem to conduct study on SAF plant

NextChem subsidiary MyRechemical has been awarded an engineering study contract by Altalto Ltd. for a sustainable aviation fuel (SAF) plant in Immingham, Lincolnshire, based on its proprietary NX CircularTM gasification and NX CPOTM technologies. Altalto is a company set up by Velocys to develop SAF projects in the UK. The plant is expected to be operational in 2030. Initial targets include the production of 23,000 t/a of SAF for the UK market. Feedstock will be sourced from residual municipal solid waste (MSW) and commercial and industrial waste. The project has been awarded a grant from the UK Department for Transport’s Advanced Fuels Fund to progress basic engineering design. MyRechemical will operate as a technology provider and as coordinator for other technological partners. It will also supply engineering services.

NX Circular gasification technology allows the plant to convert waste by generating syngas, which is subsequently transformed to syncrude through Velocys’ Fischer-Tropsch technology and upgraded to high-quality sustainable fuels. NX CPO technology produces synthesis gas via controlled partial oxidation through a very fast reaction, is contributing to maximising overall yield while minimising carbon intensity of the product.

Completion of refinery upgrade

Maire Group subsidiary KTKinetics Technology says that it has completed work on the Rijeka Refinery Upgrade Project in Croatia, having completed the engineering, procurement and construction activities. The scope of work included a new delayed coking unit to process heavy residue and eliminate the production of fuel oil while increasing refinery efficiency capacity, the revamping of the process units and the utility network and the implementation of the latest solutions for coke handling and storage and sea jetty construction and shipping loading facilities.

Grupa Azoty adds new sulphur fertilizer to its range

Grupa Azoty has launched DuoS® , a new nitrogen–sulphur fertilizer. Its formulation is based on ammonium sulphate, ammonium nitrate and anhydrite and includes two forms of nitrogen – nitrate and ammonium; two sulphur sources – ammonium sulphate and anhydrite; and calcium to support crop resilience and the quality of produce. The new nitrogen–sulphur fertilizer with added calcium is designed to improve nutrient use efficiency and reduce leaching and other nutrient losses. It is recommended for pre-sowing and top dressing on winter and spring cereals, winter rapeseed, sugar beet, potatoes, legumes, grassland, as well as vegetables and fruit crops. Grupa Azoty says it is introducing DuoS® in the current season as part of a strategy to develop its fertilizer business and focus on specialty products.
