Pulp and Paper Manufacturing Process Overview
Papermaking is the process of turning pulp into paper products. The process typically involves several stages, including stock preparation, forming, pressing, and drying. Stock preparation involves blending the pulp with water and other additives like starch, dyes, and fillers. The resulting mixture is called the paper stock.
Pulp and Paper Making Process
Chemical recovery is an essential part of the pulp production process (Tran 2007; Vakkilainen 2000; Bajpai 2008; Biermann 1996). Half of the wood raw material is utilized as chemical pulp fiber. The other half is utilized as fuel for electricity and heat generation. In fact, a pulp mill has two main lines.
