Waste to methanol plant development

Maire Group subsidiary MET Development, together with Eni and utility company Iren Ambiente, have started the permitting process for a renewable methanol and hydrogen plant at Eni’s refinery in Sannazzaro de’ Burgondi near Pavia. The plant will be developed using NextChem’s NX Circular™ technology, which allows the plant to convert waste by generating syngas, which is subsequently used to produce high quality sustainable fuels and chemicals. Once completed, the plant will be able to convert approximately 200,000 t/a of non-recyclable waste supplied by Iren’s waste management unit Iren Ambiente into synthesis gas. This will in turn be converted to produce up to 110,000 t/a of renewable methanol, as a potential fuel for decarbonisation of the maritime sector. It will also produce up to 1,500 t/a of hydrogen, which could be used in refinery processes, reducing CO2 emissions compared to fossil-generated hydrogen, or, alternatively, for sustainable mobility in road and rail transport. The plant will also recover 33,000 t/a of inert granulate, which can be used for the cement industry. The plant will use infrastructure and services already available at the refinery to optimise costs.

Orica saves 1 million tonnes of CO2

Orica says it has achieved a decarbonisation milestone by eliminating 1.0 million tonnes of carbon dioxide equivalent (CO2-e) from its Kooragang Island site, the equivalent of taking 600,000 cars off the road. The emissions reduction is the result of deployment of tertiary abatement technology on three nitric acid plants, in a project co-financed by the New South Wales Government’s Net Zero Industry and Innovation Program and the Federal Government’s Clean Energy Finance Corporation. The Clean Energy Regulator also approved the project as eligible to generate Australian carbon credit units.

MOL co-produces HVO and SAF

MOL Group has produced a diesel fuel containing hydrotreated vegetable oil (HVO), and sustainable aviation fuel (SAF) at the Slovnaft refinery in Bratislava. The HVO was produced using oil from cashew nut shells and the biocomponent produced this way was processed together with crude oil. MOL has already been using co-processing at its Danube Refinery in Százhalombatta for some years, mixing plant residues, as the bio and fossil fuel components are processed simultaneously during production. The SAF at Bratislava was also produced via co-processing, using partially refined cooking oil together with more traditional raw materials.

TotalEnergies to decarbonise its refineries in Northern Europe

TotalEnergies has signed agreements with Air Liquide to develop two projects in the Netherlands for the production and delivery of some 45,000 t/a of green hydrogen produced using renewable power, generated mostly by the OranjeWind offshore wind farm, developed by TotalEnergies (50%) and RWE (50%). These projects will cut CO2 emissions from TotalEnergies’ refineries in Belgium and the Netherlands by up to 450,000 t/a and contribute to the European renewable energy targets in transport.

Ammonia combustion for large furnaces

Ammonia has been recognised as an advantageous hydrogen and energy carrier. This article focuses on the use of ammonia as fuel in steam reformers and ammonia crackers in order to reduce or completely eliminate direct CO2 emissions. Ammonia combustion knowledge is especially important for ammonia crackers with respect to the recycling of unconverted ammonia. Air Liquide is constructing an industrial scale pilot plant in Antwerp, planned to be operational in 2024, that will be used to demonstrate ammonia cracking and combustion in a process furnace with a multiple burner configuration.

A smarter way to treat lean sulphurous off-gases

The implementation of WSA technology to recover sulphur as sulphuric acid from lean sulphurous off-gases offers significant environmental benefits. These include waste reduction, resource efficiency and reduced overall CO2 e footprint, while also producing profitable sulphuric acid. By embracing such practices, industries can ensure improved or better consumption and production patterns and foster a more sustainable and responsible future. J. Feddersen and S. S. Johansson of Topsoe illustrate these benefits using three distinct industrial applications where WSA technology provides a smarter way to treat sulphurous off-gases. It is not only waste stream management in the three cases, but also reduced transportation of chemicals, reduced opex and reduced CO2 e footprint.
