Geology: What Is Fossiliferous Limestone

 · Some examples of chemical sedimentary rocks are crystalline or fossiliferous limestone, chalk, chert, gypsum, rock salt and bituminous coal. Limestone Different types of limestone are classified based on the texture, mineral content, origin and geological age, but all limestone is part or wholly organic and may contain fossilized shells and plants.

 · The present paper presents two process functions for the estimation of the energy demand for $$hbox {SO}_{2}$$ SO2 filtering from coal flue gas streams and the gypsum production by wet flue gas desulfurization (WFGD) systems. Functions are prepared to be used as plugins on conceptual design procedures of industrial processes based on coal combustion with some sulfur content without the …

Flue Gas Desulfurisation

Flue gas desulfurization (FGD) is a very common method for gas claning adopted in a gas processing plant. In this process, the flue gas with acid vapors is scrubbed to remove it as a by-product. Most of the FGD processes use alkali to scrub the flue gas. Many designers of …

gypsum

Gypsum deposits lie in flat beds of about six to eight feet in thickness, and are often inter-layered with limestone or shale. Gypsum deposits were formed millions of years ago when salt water oceans covered most of the earth, and as they receded, may inland "dead" seas were formed which, as evaporation continued, became more and more salty.

AI-50 SPREADER

The AI 50 is a high-output, multi-purpose, all-terrain implement that spreads limestone, gypsum, dolomite, sand, manure or compost accurately and evenly, also at extreme angles. Its 750cc high-torque hydraulic motor powers a unique three-chain system and dual spinners, without requiring a complex and often unreliable transmission system typically used in other spreaders.
