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...
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...
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...
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...
