In the Kraft pulping process, wood fibers are separated, and resinous materials removed, using an alkaline (typically sodium hydroxide and sodium sulfide) cooking liquor, also known as white liquor. This process converts wood into cellulosic pulp used in the papermaking process. This digesting process turns the white liquor into black liquor, which contains: …lignin fragments, […]
A pulp mill: …converts wood chips or other plant fibre source into a thick fibre board which can be shipped to a paper mill for further processing. Level measurements can be challenging in pulp manufacturing process. In a Pulp-paperworld article, Radar Technology Overcomes the Toughest Level Measurement Challenges, Emerson’s Ingemar Serneby shares his expertise on […]
Italian recycled paperboard producer, Reno De Medici (RDM) Blendecques mill in Saint Omer, France had a big challenge to modernize a control system with a short time window during a planned shutdown. The control system managed two Heat Recovery Steam Generators (HRSGs) that produce steam for the process from two gas turbines and additional burners. […]
When optimizing operating costs at a production facility, the bias is toward that which can be measured. For example, the cost of chemicals additives for a process is something easily measured based upon the amount consumed. For components such as the energy to produce steam, the costs may not be so clear. Emerson’s Barbara Hamilton […]
Wireless communications technologies are pervasive in our lives and in our world of process automation and control. Not only for smart instrumentation, but also for process manufacturing and production operating and maintenance personnel. In a PPI Mills and Technology article, Wireless technology: empowering the mill worker, the author shares a story of mobile worker technology […]
