Successfully Applying Non-Contacting Radar in Black Liquor Mixing Tanks

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, carbohydrates from the breakdown of...

Non-Contacting Radar Level Measurement in Pulp Mills

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. Ingemar Serneby 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 how non-contacting radar level...

Improved Emissions and Lower Fuel Costs at RDM Blendecques

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. Even more important was the need to reduce emissions by optimizing...

Identifying Components then Optimizing Industrial Energy Consumption

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 shared a couple of stories with me about how cost optimizations changed once unknown...
