Influence of Casing Surface Roughness on Cement Plug Integrity
Shiyou jixie, 2021 Evaluation of cement plug integrity is important for successful abandonment operations. Cement plug integrity is influenced by cement filling, but the effect of casing surface roughness on cement plug sealing has not been studied. Norwegian University of

CO2 abatement, competitiveness and leakage in the European cement industry under the EU ETS: Grandfathering vs. output-based allocation [PDF]
A recurrent concern raised by the European GHG Emissions Trading System (ETS) is the fear of EU industry competitiveness loss: a loss in domestic production and a loss in profits.

Prospective LCA of E‐Methanol Along the Transformation of Steel Industry
Chemie Ingenieur Technik, EarlyView.The environmental effects of change in steel production route on e‐methanol production are analyzed as they shift from blast furnace route to direct reduction route. Specific hydrogen demand reduces, as do the avoided CO2 emissions. E‐methanol's overall carbon footprint stays in a narrow range of −1 to −1.1 kg‐CO2‐eq./kg‐methanol.

Cement Self-Healing as a Result of CO2 Leakage
Energy Procedia, 2016 AbstractAvoiding CO2 leakages from storage reservoirs is crucial to ensure safe and cost-efficient Carbon Capture and Storage (CCS). This can only be done if effort is made to maintain well integrity throughout the entire life-cycle of a well. Cement integrity is especially important, since the interfaces between cement and rock or casing have been ...

The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study investigates the effect of moisture on CO2 adsorption in South African coals using both experimental and machine learning approaches. Three coal samples (SL, TN, and EM) with varying ranks (RoVmr: 3.49%, 1.26%, and 0.64%, respectively) were collected from different regions of South Africa.

ChemSusChem, Volume 18, Issue 6, March 15, 2025.The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

Deep Underground Science and Engineering, EarlyView.Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.

Leakage from climate policies and border tax adjustment:lessons from a geographic model of the cement industry [PDF]
We present a spatial international trade model, GEO, which computes transportation costs bynot treating markets as dimensionless points and explicitly represents capacity shortages andinvestment decisions in new production capacities.
