Ash aggregation enhanced by deposition and redistribution of salt on the surface of volcanic ash in eruption plumes [PDF]
Scientific Reports, 2017 AbstractInteractions with volcanic gases in eruption plumes produce soluble salt deposits on the surface of volcanic ash. While it has been postulated that saturation-driven precipitation of salts following the dissolution of ash surfaces by condensed acidic liquids is a primary mechanism of salt formation during an eruption, it is only recently that ...

Evaluation of fly ash concrete in salt environment
E3S Web of Conferences, 2023 Indonesia is an archipelagic country with many buildings located in the coastal area. Seawater contains 3.5% salt, which can eat away at the strength and durability of concrete. Sodium salts can be dangerous when combined with reactive alkaline aggregates, and the crystallization of salts in concrete cavities can destroy them due to crystallization ...

The effect of biomass ashes and potassium salts on MEA degradation for BECCS [PDF]
International Journal of Greenhouse Gas Control, 2021 This study investigates the comparative impact of inherently different biomass and coal ashes on the laboratory and pilot scale degradation of 30 wt% aqueous monoethanolamine (MEA), relevant to post-combustion CO2 capture. Thermal and oxidative degradation experiments were carried out at 135 °C and 40 °C respectively with CO2 loading (0.5 molCO2/molMEA)

Interactions of PbCl2 with Alkali Salts in Ash Deposits and Effects on Boiler Corrosion [PDF]
Energy & Fuels, 2018 Abstract A novel temperature gradient laboratory-scale corrosion test method was used to study PbCl2 migration, interactions with SiO2, NaCl, Na2SO4, KCl, K2SO4, or NaCl–KCl (50:50 wt %) and corrosion of carbon steel in waste-fired boilers. Two different steel temperatures (200 and 400 °C) were tested.

EXPERIMENTS ON AN ASH-FREE DIET AND SALT METABOLISM [PDF]
Journal of the American Medical Association, 1908 The role played by the inorganic salts in diabetes mellitus has not attracted much attention. It was therefore a matter of considerable interest when Taylor 1 noted the presence of acetone and diacetic acid in the urine and acetone in the breath while he was living on an ash-free diet.

Silica and Ash in the Salt Marsh Rush, Juncus roemerianus
Gulf Research Reports, 1978 Silica content of living rhizomes from the perennial salt marsh rush Juncus roemerianus had values of 0.34, 0.20, and 0.60% of dry weight in three morphologically distinct populations along the Mississippi coast and was directly related to available silica content of the soil (29.7, 17.0, 169.6 mg/100g soil, respectively).

Durability Performance of Concrete with Fly Ash as Fine Aggregate Eroded by Chloride Salt
Advances in Materials Science and Engineering, 2022 The aim of this study is to investigate the durability of concrete with fly ash as a fine aggregate (CFA) in chloride salt environments. The natural diffusion method is used to analyze the concrete strength, chloride ion concentration, and diffusion coefficient after chloride salt erosion in a laboratory environment.

Advanced Science, EarlyView.An architecture‐guided recycling process enables selective metal recovery from end‐of‐life perovskite solar modules by exploiting interfacial accessibility and calcination‐induced phase transformation. The process achieves >99.8% Pb removal, >99.7% In recovery, and >96.1% Cu recovery, while selectively retaining Sn in leaching residue.
