In a traditional continuous Kraft (Sulfate) pulping process, consider the following major steps:
Bleaching $\text{(BL)}$, Chipping $\text{(CH)}$, Debarking $\text{(DE)}$, Digestion $\text{(DI)}$, and Pulp Washing $\text{(WA)}$.
Which one of the following is the CORRECT sequence of steps for this process?
- $\mathrm{DE} \rightarrow \mathrm{BL} \rightarrow \mathrm{WA} \rightarrow \mathrm{DI} \rightarrow \mathrm{CH}$
- $\mathrm{DE} \rightarrow \mathrm{CH} \rightarrow \mathrm{DI} \rightarrow \mathrm{WA} \rightarrow \mathrm{BL}$
- $\mathrm{DE} \rightarrow \mathrm{CH} \rightarrow \mathrm{WA} \rightarrow \mathrm{DI} \rightarrow \mathrm{BL}$
- $\mathrm{DE} \rightarrow \mathrm{BL} \rightarrow \mathrm{WA} \rightarrow \mathrm{CH} \rightarrow \mathrm{DI}$
