Mill With Liquid Recovery

Kraft process Wikipedia

The invention of the recovery boiler by G. H. Tomlinson in the early 1930s was a milestone in the advancement of the kraft process. It enabled the recovery and reuse of the inorganic pulping chemicals such that a kraft mill is a nearly closed-cycle process with respect to inorganic chemicals, apart from those used in the bleaching process.Онлайн-запрос

Recovery Boiler an overview | ScienceDirect Topics

The development of the recovery boiler by Tomlinson in conjunction with Babcock & Wilcox in the early 1930s led to the predominance of the kraft process. Fig. 17.7 shows a typical recovery boiler design, while Fig. 17.8 compares two types of boilers with widespread use. Fig. 17.9 shows a recovery boiler building at a brown paper mill.

Multi-effect evaporators and concentrators

Black liquor evaporation is an essential part of the chemical recovery process as it significantly concentrates the dry solid matter in black liquor so that the liquor can be effectively combusted in recovery boiler. The water removed from the liquor can be segregated and processed so that it can be reused in the mill – reducing fresh water requirements, effluents, and saving money. ANDRITZОнлайн-запрос

liquid stream called weak black liquor (Figure 1). The weak black liquor is separated from the pulp by washing, and is sent to the kraft recovery system, where the inorganic pulping chemicals are recovered for reuse, while the dissolved organics are used as a fuel to make steam and power. For every ton of pulp produced, the kraft pulping process produces about 10 tons of weak black liquor orОнлайн-запрос

Black liquor Wikipedia

Early kraft pulp mills discharged black liquor to watercourses. Black liquor is quite toxic to aquatic life, and causes a very dark caramel color in the water. The invention of the recovery boiler by G.H. Tomlinson in the early 1930s was a milestone in the advancement of the kraft process. By 2000, [citation needed] the better kraft mills recovered 99.5% or more of the black liquor, andОнлайн-запрос
