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.

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.

Producing sulphuric acid from gas streams with variable SO2

The first installed combination of a regenerative SO2 scrubbing system with a sulphuric acid plant using Worley Chemetics’ CORE™ reactor technology started up in November 2022. The combination of these technologies allows production of high-grade sulphuric acid from gases with low and/or fluctuating SO2 concentrations. C. Trujillo Sanchez and R. Dijkstra of Worley Chemetics report on the design concepts of this integrated process, highlight where it is most effective and report on the start-up and first years of operation of the plant.

Decarbonisation in the sulphuric acid industry

New concepts focused on the transfer and combination of existing sulphur and sulphuric acid technologies to support decarbonisation of the sulphuric acid industry are being investigated. In this article three research projects are discussed: sulphur dioxide depolarised electrolysis for green regeneration of spent acid, use of renewable heat and catalyst to the splitting process from sulphuric acid to SO2 for reduction of fossil fuel consumption, and sulphur as an energy vector.
