## Abstract __The absorption of CO~2~ by aqueous NH~3~ solutions has been investigated at atmospheric pressure and 0βΒ°C. The CO~2~ absorption is fast and occurs with high efficiency (88β99β%). The maximum CO~2~βremoval efficiency increases slightly with the NH~3~ concentration. Addition of zinc(II)
## Abstract A new type of process for producing highβpurity calcium carbonate from waste cement powder was developed. The process consists of two main reactions; extraction of calcium in the form of calcium ions from waste cement powder in a water slurry by pressurized CO~2~ (typically at several M
