Debottlenecking a Pulp Mill by Producing Biofuels from

Apr 14, 2021 · As described in the introduction, current Kraft pulp mills produce pulp (∼50 % yield), extractives (<5 %), and excess energy. As the recovery boiler is the limiting operation in all pulp mills, there are two options to increase pulp production in the pulp mill: 1) change the recovery boiler to one with a higher capacity; or 2) extract lignin.

Sulfite process - Wikipedia

The sulfite process produces wood pulp that is almost pure cellulose fibers by treating wood chips with solutions of sulfite and bisulfite ions. These chemicals cleave the bonds between the cellulose and lignin components of the lignocellulose. A variety of sulfite/bisulfite salts are used, including sodium (Na +), calcium (Ca 2+), potassium (K +), magnesium (Mg 2+), and ammonium (NH 4 +).
