Chapter 3745-73 Total Reduced Sulfur

3745-73-01 Definitions.

(A) The definitions in this rule shall apply to this chapter.

(B) “Black liquor” means the spent cooking liquor, composed of a mixture of dissolved lignins and inorganic compounds, which remains after the digestion of wood chips in the Kraft pulping process.

(D) “Condensate stripper system” means a system in which total reduced sulfur gasses, partially dissolved in the digester and multiple effect evaporator off-gas condensate, are stripped by means of a countercurrent flow of air or steam in multi-stage columns.

(E) “Digester system” means any continuous or batch process in which white liquor is used to cook the wood pulp, and includes any associated flash tanks, blow tanks, chip steamers and condensors.

(F) “Kraft pulp mill” means a wood pulping mill which uses an alkaline sulfide solution containing sodium hydroxide and sodium sulfide (white liquor) in the wood digesting process.

(G) “Lime kiln” means a unit used to calcine calcium carbonate, commonly known as “lime mud,” into calcium oxide, commonly known as “quicklime.”

(H) “Multiple-effect evaporator system” means the multiple-effect evaporator including any associated condensors and hotwells used to concentrate the black liquor.

(I) “Recovery furnace” means a straight Kraft recovery furnace including any direct contact evaporators, designed to recover chemicals necessary for the pulp cooking process through the combustion of black liquor containing less than seven per cent liquor such as neutral sulfite semichemical from a soda-based semichemical pulping process on a quarterly basis.

(J) “Smelt dissolving tank” means a vessel used for dissolving smelt from a recovery furnace.

(K) “Soda-based semichemical pulping operation” means any operation in which pulp is produced from wood by cooking or digesting wood chips in a soda-based semichemical such as neutral sulfite semichemical.

(L) “Total reduced sulfur” means the sum of the sulfur compounds hydrogen sulfide, methyl mercaptain, dimethyl sulfide and dimethyl disulfide, that are released during the Kraft pulping operation and measured by methods specified in rule 3745-73-04 of the Administrative Code.
