Calcium carbonate, the most common scale in oil and gas field operations, occurs in every geographical area. Calcium carbonate precipitation occurs when calcium ion is combined with either carbonate or bicarbonate ions as follows, The preceding equations show that the presence of CO 2 will increase the solubility of CaCO 3 in brine.

Figure 2: The reaction of calcium carbonate with hydrochloric acid is shown. (credit: Mark Ott) Other applications of carbonates include glass making—where carbonate ions serve as a source of oxide ions—and synthesis of oxides. Hydrogen carbonates are amphoteric because they act as both weak acids and weak bases.

The fineness of limestone fine powder processed by the industrial dry mill is used. It can be up to 3000 mesh. Although it can't compare with the fineness of the wet mill, it is more than enough for the production of desulfurized lime. The fineness can be adjusted from mesh, which is enough to meet the needs of most enterprises.
