Chemical pulping

Chemical pulping

BleachMag® can be used in sulphite and bisulphate pulping to replace both caustic magnesite, and soda ash or lime. The replacement of soda ash with BleachMag powder reduces the consumption of chemicals some 30 %.


Benefits in regeneration, cooking, and waste water treatment

Special attention should be payed to the low content of soluble dietary fibers which is essential for the operation of regeneration chemicals and for heat regeneration from spent liquors. Thus, the content of potassium in terms of K+ is about 0.01%, sodium salts in terms of Na+ — 0,03–0,06% and chlorides - 0.1 0.2%. BleachMag® can completely or partly eliminate the necessity of withdrawal of these compounds from the system. Moreover it contains very low quantity of Fe2O3 (about 0,1 0,5%) which is a very positive aspect.

Hydration is not required with BleachMag, therefore the process is simplified, and the cost of cooking liquors is reduced. In chemical pulping with caustic magnesite, the hydration is necessary.

Furthermore, BleachMag can be used for neutralization of wastewater. A benefit of BleachMag is here the fact that the pH level of the neutralized wastewater even with strong excess of BleachMag does not exceed 9 - 10 in contrast to the 12 - 14 with excess of lime or caustic soda. The consumption of BleachMag is 20 25 % lower than that of lime or caustic soda, and 40 45 % lower than consumption of soda ash.
