Calcium looping (CaL) is one of the most promising technologies for CO2 capture in cement plants. The process comprises two basic steps: (1) “carbonation” of CaO to form CaCO3 in a reactor operating around 650°C; (2) oxyfuel calcination in a reactor operating at 920-950°C, which makes the CaO available again and generates a gas stream of nearly-pure CO2.

2020-8-15 · In metallurgy, a flux (derived from Latin fluxus meaning "flow") is a chemical cleaning agent, flowing agent, or purifying agent. Fluxes may have more than one function at a time. They are used in both extractive metallurgy and metal joining. Some of the earliest known fluxes were sodium carbonate, potash, charcoal, coke, borax, lime, lead sulfide and certain minerals containing phosphorus.

Indium Corporation Ultrafine flux-cored wire capabilities Indium Corporation announces that it is now offering ultrafine flux-cored wire down to 0.006 " (0.15mm) in diameter for standard Pb-free alloys.Indium Corporation ''s ultrafine flux-cored wire was developed to meet the progressively demanding requirements for increased solder joint density and miniaturization in appliions where solder
The calcium-silicon-coated cored wire is processed by the calcium-silicon alloy into powder and then is wrapped by the steel strip and then processed by the core-wire machine. It not only retains the original deoxidizing effect of the calcium-silicon alloy but also increases the depth of the calcium reaction, Calcium recovery rate, is a good
wires made by the OPIT process (1G wire) are expensive, since the major component is high-purity silver. In the RABiTS process, silver is replaced by low-cost nickel or a nickel alloy, which allows the fabriion of HTS wires at a lower cost. The RABiTS architecture most commonly used consists of a starting template of bi-
