CT: Because today coal-getting is concentrated at a few working places where output is greatest, ‘natural’ homogenization of raw coal in the course of mining has become limited. More coal homogenization depots or bunkers must therefore be provided in conjunction with mixed end product depots, which, apart from leading to improved qualities of end product, will also bring about considerable economic advantages in the area of coal preparation. It will besides enable the consumption requirements of coking plants to be met, in particular from the point of view of product uniformity, and mitigate the increasing risk of defective sortings arising from concentrated face-working.

N: 1. – coking (adj): From noun “coke” [“fuel residue, solid product of the carbonization of coal,”an important substance in metallurgy, 1660s, a northern England dialect word, perhaps a variant of Middle English colke “core (of an apple), heart of an onion” (c. 1400), also “charcoal” (early 15c.), a word of uncertain origin. It seems to have cognates in Old Frisian and Middle Dutch kolk “pothole,” Old English -colc, in compounds, “pit, hollow,” Swedish dialectal kälk “pith.” Perhaps the notion is the “core” of the coal, or “what is left in the pit after a fire.”] + suffix “-ing” (verb suffix, used to form the present participle; adjective suffix, used to form an adjective resembling a present participle but not derived from a verb).
– plant (n): Old English plante “young tree or shrub, herb newly planted, a shoot or strip recently sprouted from seed,” from Latin planta “sprout, shoot, cutting” (source of Spanish planta, French plante), which is perhaps from an unattested verb *plantare “to drive in with the feet, push into the ground with the feet,” or perhaps “to level the earth,” from planta “sole of the foot,” from nasalized form of PIE root *plat- “to spread.”  German Pflanz, Irish cland, Welsh plant also are from Latin.
Broader sense of “any small vegetable life, vegetation generally” (sometimes popularly excluding trees), “an individual living being with material organization but not animal in nature” is recorded by 1550s.
Most extended usages are from the verb, on the notion of “something planted;” such as “construction for an industrial process,” 1789, at first with reference to the machinery, tools, apparatus, etc., later also the building; also slang meaning “a spy” (1812). Many of these follow similar developments in the French form of the word.
2. A plant for converting metallurgical grade coal to coke for use in blast furnaces.
3. The coking plant is the by-product plant. Hot tarry gases leaving the ovens are collected, drawn away, and cooled. Crude tar separates and is removed for refining. The crude coke oven gas is scrubbed free of ammonia, and then usually crude benzol is removed from it.
