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.

Optimisation of the nitric acid process depends on good process visualisation tailored to the specific process parameters of the plant, improvements in combustion efficiency, reduction of N2 O emissions and the optimal use of platinum group metals.

Most nitric acid is used for production of fertilizer nitrates and ammonium nitrate explosives, but it is also used in polyamides, polyurethanes and aniline dyes as well as a number of industrial processes including ore treatment. High ammonia prices have pushed nitric acid prices to record levels this year, but growth predictions remain robust.

Clariant has announced a reorganisation into three global business units instead of the previous five, with the business unit presidents to be located in the regions with the largest customer base and highest growth potential for the respective businesses. It will also create a new executive steering committee that will include the CEO, the CFO and the presidents of the new business units.

In a major blow to the British fertilizer industry, CF Fertilisers UK announced the closure of its Ince production site in north-west England in June (see p8). Ince is the UK’s largest compound fertilizer producer, operating three NPK+S units. It also manufactures large volumes of ammonium nitrate (AN) for Britain’s farmers. At the heart of the Cheshire complex is Ince’s long-standing ammonia plant. Unfortunately, high natural gas costs have kept this shuttered since September last year.

Clariant has announced a reorganisation into three global business units instead of the previous five, with the business unit presidents to be located in the regions with the largest customer base and highest growth potential for the respective businesses. It will also create a new executive steering committee that will include the CEO, the CFO and the presidents of the new business units. The company says that the new structure aims to reduce hierarchical layers, foster greater accountability, speed up decision-making processes and enhance customer proximity, while strengthening diversity.

By using modular construction, operational modelling and digital plant control, thyssenkrupp Uhde can offer customers fast-build, capital efficient green ammonia plants. Dr Christian Renk and Dr Klaus Nölker explain the company’s innovative approach to plant construction, design and control.

Gidara Energy has agreed with the Port of Rotterdam to develop a new waste to methanol facility in the Netherlands: Advanced Methanol Rotterdam (AMR). Gidara will duplicate its Advanced Methanol Amsterdam project as a template for AMR, using Gidara’s patented high temperature Winkler (HTW® ) technology, which converts nonrecyclable waste to renewable fuels. This technology has been used commercially in four other waste to syngas production facilities. AMR will convert around 180,000 t/a of non-recyclable waste into 90,000 t/a of methanol, while capturing all waste streams for use; CO2 will be captured and led to local greenhouses; bottom product residue will be used for cement production; and other streams like ammonia and salts will be sold and put to use as feed stock for other industries and road salt respectively, creating a fully circular concept. The facility is scheduled to start detail engineering and construction in the first half of 2023, when a permit is received, and start production of renewable methanol in 2025.

Casale has acquired Hong Kong-based Green Granulation Ltd (GGL), and its proprietary technologies for the design and construction of urea and calcium ammonium nitrate (CAN) granulation systems. Casale says that the takeover is part of a broader strategy aimed at strengthening its leading position in the nitrogen market by leveraging the widest integrated portfolio of efficient technologies, enabling the company to offer a ‘one stop shop’ for the entire production cycle of nitrogen-based fertilizers, from raw materials to final products. GGL’s addition to the Casale group includes the Cold Recycle Granulation process, an advanced fluidised bed technology designed to accept a lower concentration of urea feed melt (ca 96% urea and biuret), as well as a proprietary design for both granulator and scrubber, a team of experts and qualified technicians, and considerable experience in several industrial references. The CRG design has a horizontal layout, leading to lower structural costs and higher efficiency, as well as lower total investment costs and power consumption, lower power consumption and simplified operation, and higher operational flexibility in urea and CAN granulation.
