Control of sulfidity in a modern kraft pulp mill
pulp mill Executive Summary Many years ago, the kraft pulping liquor circuit used sodium sulfate salt as the main make-up source of cooking chemicals. The make-up chemical has given its name to the process in many languages. Back then, the sulfidity reached an equilibrium level that was dependent on the leakages.

10.2 Chemical Wood Pulping
A major source of emissions in a kraft mill is the boiler for generating auxiliary steam and power. The fuels are coal, oil, natural gas, or bark/wood waste. See Chapter 1, "External Combustion Sources", for emission factors for boilers. Table 10.2-1 presents emission factors for a conventional kraft mill. The most widely used

Crystallization and control of sodium salt scales in black liquor concentrators. In this report on a four-year study, the researchers identify a double salt of Na 2 CO 3 and Na 2 SO 4 that crystallizes in most kraft black liquors. This double salt causes soluble scale fouling in high-solids black liquor concentrators.

The higher reactivity of orthorhombic C 3 A (ort-C 3 A) in sulfate-containing solutions, compared with cubic C 3 A (cb-C 3 A), was previously related to the differences in crystal structure or the sodium in the ort-C 3 A pore solution. We analyzed the hydration of cb-C 3 A (in water and NaOH solution) and Na-doped ort-C 3 A in the presence of gypsum and hemihydrate.

The sodium sulfate is not the active chemical during the kraft pulping process but only the source to generate sodium sulfide (Na 2 S). Most of the sodium sulfate in the recovery boiler is reduced to Na 2 S. The efficiency of this reduction is called reduction efficiency and normal values are in the range of 90–94 per cent.

Sodium Sulfites - an overview | ScienceDirect Topics
Sodium sulfite (CAS ) is an odorless, solid white powder with a salty sulfurous taste that is soluble in water. It is primarily used as a food preservative (e.g., to prevent dried fruit from discoloring) and as an antioxidant. In the past, sodium sulfite was used to make pulp in the paper industry, but its use now accounts for less ...
Controlling sulfidity in a modern kraft pulp mill, case study
Reduced sulfur causes smell in the mill's surroundings and oxidized sulfur contributes to the large-scale acidification of soil, which negatively affects vegetation and biodiversity. Today, both environmental and economic forces have reduced the leakages and most modern mills have practically eliminated sulfur emissions to the atmosphere.
