Chapter 8. Pulp and Paper
Formula 1 gives 10 = [(2,000 lb – DP) / 2,000 lb] * 100 solving: DP = 1,800 lb of oven-dry fiber per ton of pulp. Formula 2 gives 45 = (1,800 lb / DW) * 100 solving: DW = 4,000 lb oven-dry wood per ton of pulp. Here the yield of bleached kraft pulp is assumed to be 45% (Figure 8-1). 3 solving: V = 153 cubic feet of green wood per ton of pulp.
