Gypsum is dried and fed to a rotary kiln with fine coal. The produced limestone can be utilized in the neutralization phase of the water treatment process. In 2009 a pilot plant (capacity 1.2 t/d dry gypsum) was commissioned for the testing of the process.

Limestone is converted into lime through heating in a kiln, a process known as calcination. When limestone is subjected to high temperatures, it undergoes a chemical decomposition resulting in the formation of lime (CaO) and the emission of carbon dioxide gas (CO 2).

Limestone-based wet FGD systems which can remove 90–99 per cent of SO 2 are the dominant choice for thermal power stations globally11 (see Graph 1: FGD technology global population).

Raw materials are the things which are used to manufacture urea. These raw materials are taken from other industries or produced themselves inside the plant. Liquid ammonia - NH 3; Liquid carbon dioxide - CO 2; Ammonia is manufactured by haber process in the industry. Carbon dioxide (CO 2) is prepared by decomposition of limestone (CaCO 3).

Limestone uses. The calcium carbonate content of limestone rocks has been used from the earliest civilisations, dating back to 14,000 BCE, to its extensive use in modern times. It is a valuable resource that services the needs of a multitude of industries. Calcium carbonate is used as a filler in the manufacture of white paper.

The basic processes in the production of limestone are (i) quarrying of raw limestone, (ii) preparing mined limestone for its use by crushing and sizing, (iii) calcining of raw limestone, (iv) processing the calcined limestone further by hydrating to produce hydrated lime if required for use, and (v) miscellaneous transfer, storage, and handling operations.

In order to eliminate the SO 2, the flue exhaust gases from a coal-fired power plant are usually passed through a spray of limestone slurry in the scrubber. The resultant reaction typically traps over 90% of the SO 2. Nearly 80%–85% of the global FGD units set up in power plants use wet limestone scrubbing compared to other technologies.

He concludes that such processes are about equal to direct limestone/lime processes with regard to SO 2 removal efficiency, power consumption, and operability (Ando, 1977). In the U.S., six relatively small double alkali plants were operational and two large power plant installations were under construction in mid-1977 ( Pedco, 1977 ; Kaplan, 1976 ).

Both limestone and dolomite are extensively used in an iron and steel plant in various processes. Specification of limestone and dolomite for iron making is less rigid. But for steelmaking limestone need to have very low SiO2 and Al2O3 since these elements require additional flux to neutralize them which increases the slag volumes.

The principle of our process is to make use of the natural alkalinity of seawater instead of using limestone solution to absorb acidic substances in the flue gas.
