The article is devoted to the study of the influence of residual sulfuric and phosphoric acids on the process of processing large-tonnage phosphogypsum (PG) waste into calcium carbonate. In the Russian Federation, about 10 percent of existing phosphogypsum waste is processed into construction materials. Acidic impurities The process efficiency is examined in terms of starting material concentrations, and the feasibility of the process on industrial grade calcium carbonate is demonstrated. Methods to separate the products are also outlined, along with two conceptual process designs and energy performance calculations. 2.

Calcium carbonate scaling in reverse osmosis (RO) desalination process is studied in the presence of two novel fluorescent-tagged scale inhibitors 1,8-naphthalimide-tagged polyacrylate (PAA-F1) and 1-hydroxy-7-(6-methoxy-1,3-dioxo-1H-benzo[de]isoquinolin-2(3H)-yl)heptane-1,1-diyl-bis(phosphonic acid) (HEDP-F) by High-density, high-permanence forms of carbon storage are in demand to save storage space on land or at sea while allowing the world to reach its climate targets. Biochar and calcium carbonate are two such forms that have been considered largely separately in the literature for carbon storage. In this paper, we consider how biochar and Toward Carbon-Neutral Concrete through Biochar–Cement–Calcium Carbonate

The absorption of CO 2 by regenerable solvent is an effective approach to post-combustion decarbonation and produce concentrated CO 2 stream for sequestration. However, the high demand of energy in regenerating solvent after the capture of CO 2 is the bottleneck of the process [].Take the most common absorbent monoethanolamine Calcium carbonate is an important component in exoskeletons of many organisms. The synthesis of calcium carbonate was performed by mixing dimethyl carbonate and an aqueous solution of calcium chloride dihydrate.

Calcium carbonate is a naturally occurring and renewable mineral. It provides value to polypropylene nonwovens. By replacing 10% polypropylene with calcium carbonate, the equivalent CO 2 emissions can be reduced by 8.5%. Main benefits are the improved sustainability, opacity, haptic properties, and cost savings.Samples were extracted at intervals from an industrial micro-deep drawing process line to evaluate how the lubricant changes over time.
