Brazil: Votorantim Cimentos has installed a chlorine bypass at its integrated Vidal Ramos plant in Santa Catarina. The US$10m upgrade is intended to allow the unit to process more alternative fuels such as plastics, fabrics and personal protective equipment. The company says it is the first such installation in the country. It will allow the plant to increase its co-processing volumes by 62% to 73,000t/yr from 45,000t/yr. In 2021 the plant used 65,000t of petcoke. This is expected to fall to 53,000t/yr with the addition of the chlorine bypass, reducing CO₂ emissions by 5% or 12,200t.

Australia: Boral plans to install chlorine bypass technology at its Berrima cement plant in New South Wales. The Illawara Mercury newspaper has reported that the installation will help the plant to double its alternative fuel (AF) substitution rate to 100%. This is one of the ways in which the producer aims to reduce its Scope One and Two emissions by 46% between 2020 and 2030.

Portugal: Cimpor Cement plans to upgrade the kiln line of its Souselas cement plant in order to enable 60% refuse-derived fuel (RDF) substitution in its fuel mix. The producer has contracted Denmark-based FLSmidth to install chlorine bypass technology in order to prevent chlorine build-up in the plant’s flue gas. Work is scheduled to begin in mid-2021, and production will stop until its completion and the commissioning of the installation in early 2022.

Cimpor Cement project manager Paulo Evangelista said, “Investing in the chlorine bypass is a key step on our journey towards reducing our environmental footprint. On top of the obvious incentives to increase our fuel substitution, like lower CO₂ emissions and financial savings, we are experiencing better waste handling infrastructure in the local area. All this has made it an easy choice to make. FLSmidth knows our Souselas site and has been key in delivering a solution that will enable this next phase on our sustainability journey.”

Hungary: Lafarge Cement Hungary has announced plans to upgrade clinker production at its 1.0Mt/yr Kiralyagyháza integrated plant with a Euro1.79m investment in chlorine bypass technology, which uses powdered limestone to remove chlorine and one tenth of the carbon dioxide (CO₂) from gases released in clinker production, which will then be used in clinker cooling. There will be a concomitant increase in the rate of alternative fuel (AF) substitution in the plant’s kilns, with an AF fuel store expansion in early 2020 set to raise AF usage to 80% from 60%.
