Removal of SO2 from Low Sulfur Coal Combustion Gases by

scrubbing process is given, and basic design variables for a 100 megawatt plant burning low sulfur coal are specified. For the immediate future, processes for removing SO2 from flue gases will most likely combine introduction of lime (CaO) or limestone (CaCO3) with the use of a wet scrubbing device. Three variations of this scheme

Sustainable Biocement Production via Microbially Induced

Biocement production from microbially induced calcium carbonate precipitation (MICP) is an environmentally friendly approach for construction works, but the use of calcium chloride (CaCl2) in the conventional MICP process is a costlimiting factor. The aim of this work is to develop a method for producing soluble calcium ions through two waste sources, limestone powder derived from aggregate

What Is Dolomite Used for With Plants? Home Guides SF Gate

Dolomite, a type of limestone, provides valuable nutrients to plants and helps change the pH of the soil by raising it to match the plants' needs. It's sometimes called dolomitic lime or dolomitic limestone, and provides more nutrients than straight lime. It's often used in addition to balanced fertilizers, particularly with seeding fruit.
