taken into the mill directly decreases the amount of scale. Having ensured effectivebark removal, the next most effective means of reducing or eliminating barium sulfate scale is to eliminate the use of spent acid from the chlorine dioxide generator for pH adjustment in thebleachplant. Spent acid is a mixture of sodium sulfate (Na2SO4) and

After cooking, the sulfate pulp passes through the . blow line to the blow tank and then on to the washing stage. During brown stock washing, the spent cooking liquors are separated from the cellulose fibers. Normally . a pulp mill has 35 washing stages in a series. The .
The R3 was developed to meet the needs for reduced sulfur byproducts from earlier chlorine dioxide processes. The R3 utilizes sodium chlorate, sulfuric acid, and sodium chloride (reducing agent) to produce chlorine dioxide, sodium sulfate (crystal coproduct) and a chlorine coproduct (as chlorine water or hypochlorite).

mill via the evaporation plant. If the recycled sodium sulfate could be split and returned to the recovery cycle as one controlled sodium and one controlled sulfur component or at least split into two flows where sulfur is enriched in one flow and sodium in the other flow, the sodium/sulfur balance would be easier controlled.
The kraft process (also known as kraft pulping or sulfate process) is a process for conversion of wood into wood pulp, which consists of almost pure cellulose fibers, the main component of kraft process entails treatment of wood chips with a hot mixture of water, sodium hydroxide (NaOH), and sodium sulfide (Na 2 S), known as white liquor, that breaks the bonds that link lignin ...

As you may have learned in organic chemistry there are multiple ways to arrive at the same raw material. Sodium lauryl sulfate can be made by reacting lauryl alcohol with sulfur xide gas, oleum, or chlorosulfuric acid. It is then neutralized with either sodium hydroxide or sodium carbonate to produce the final ingredient. Read More
can be recovered as sodium sulfate in electrostatic precipitators or in sulfur dioxide scrubbers, the preferred and more economical way of maximizing the recovery of sulfur is to control it at the source, which is the burning particle. Most of the studies on sulfur gas release have been mill .
pulp mill Executive Summary Many years ago, the kraft pulping liquor circuit used sodium sulfate salt as the main makeup source of cooking chemicals.
