Currently, the main products manufactured by Ammonium-acid process for the recovery of SO_(2) are liquid SO_(2), ammonium sulphate liquor or hydro-ammonium sulphite. 16. Non-woody magnesium lignosulfonate(ML) is produced as a by-product in the sulphite non-wood pulping, which is a very abundant and innoxious biomass resource.

In the kraft (sulphate) process, high-calcium lime works as a causticizing agent, reacting with recovered waste sodium carbonate solution to generate caustic soda for reuse in the process. Lime is also used in the preparation of calcium bisulfite; in the preparation of calcium hypochlorite bleach; in the recovery of waste black liquor solution; and as a filtration conditioner in the recovery

of the total reduced sulphur (TRS) components from the pulp mill operations. It was found that sulphate-reducing bacteria (SRB) converted the sulphates present in the effluent to hydrogen sulphide (H 2 S) by dissimilatory respiration. The combined

Most chemical pulp is made by the sulphate process (or Kraft process), in which caustic soda and sodium sulphate 'cook' the woodchips. In the unbleached stage, a dark brown but very strong pulp results and this can be bleached to a high brightness if required.

Chemistry Assignment Help, Kraft chemical recovery boiler-sodium sulfate and carbon, Question- 1. In a Kraft chemical recovery boiler, sodium sulfate and carbon (C) are combined to produce sodium sulfide and carbon dioxide. a) If 500.0 g of sodium sulfate

Pulp mill. Quite the same Wikipedia. Just better. Chemical pulping processes such as the kraft (or sulphate) process and the sulfite process remove much of the hemicelluloses and lignin. The kraft process does less damage to the cellulose fibres than the sulfite process, thereby producing stronger fibres, but the sulfite process makes pulp that is easier to bleach.
