Abstract
A process for producing calcium carbonate from calcium hydroxide derived from, for example, limestone, comprises injecting a gas containing carbon dioxide into a recirculating stream flowing in a recycle piping system in communication with a reaction vessel. The carbon dioxide containing gas is injected at a turbulent area located in the recycle piping system. By controlling reaction parameters including pH and temperature, novel calcium carbonate products are formed by the process.
