KTH Royal Institute of Technology researchers describe smarter ways to capture carbon dioxide-exploring alternatives for small- to medium-scale carbon capture in kraft pulp mills, report large potential for CCS from alternative calcination technologies

August 31, 2023 (press release) –

2023 AUG 30 (NewsRx) -- By a News Reporter-Staff News Editor at Chemicals & Chemistry Daily Daily -- Investigators publish new report on Chemicals and Chemistry. According to news reporting originating from Stockholm, Sweden , by NewsRx correspondents, research stated, “Carbon capture from the calcination process in Kraft pulp mills, also known as sulphate pulp mills, has potential as a part of carbon capture and storage (CCS) infrastructure deployment. Growing concern of climate change is increasing the interest for so-called negative emission technologies (NETs), and large emission points have great potential.”

Funders for this research include Swedish Energy Agency , Swedish strategic research programme StandUp for Energy.

Our news editors obtained a quote from the research from the KTH Royal Institute of Technology , “However, among other factors, lack of financial incentives, trade-off with investments in existing products, and the necessity of large infrastructure that stretch across country borders, constrain deployment. This study investigates two concepts for carbon capture in combination with lime kilns in Kraft pulp mills: oxyfuel combustion and electric arc plasma calcination. The results from the modelling of six configurations show that carbon capture from the calcination process with these technologies can be made with comparatively low additional energy demand. Sulphate pulp production from Kraft pulp mills, which use lime kilns, is increasing in Europe and in the world.”

According to the news editors, the research concluded: “Therefore, there is large potential for capture of CO2 from these alternative calcination technologies, both as a first step towards and as a part of a large-scale deployment of CCS and bioenergy with CCS (BECCS).”

This research has been peer-reviewed.
