Pulp & paper industry is a combination of production of raw material and production of end-products like paper, carton- or paperboard. Raw materials, fibers, are produced at pulp mills in areas where wood as raw material is available. Paper mills are typically based nearby consumers.
SICK Sensors offer solutions for the pulp and paper industry, starting with the arrival of raw materials continued on to production up to shipment of final products; as well as process control and emission monitoring according to environmental regulations.
Wood is consisting of fibers and lignins. In the pulp mill they are separated in a cooking process. Cooking chemicals are recycled, which requires several processes starting from evaporation and ending in combustion in the recovery boiler and the lime kiln. Altogether a pulp mill has 3 - 5 emission sources, where emission monitoring is required.Furthermore, many pipe lines for process gases have to be monitored and processes of handling wood and fibers have to be controlled. Solutions from SICK will support you in these applications.
Raw materials for paper, carton- or paperboard are mixed with water in order to have a homogenous mixture of materials in the head box of the paper machine. The composition of raw materials is varying according to the final product, paper, carton- or paperboard. After several steps of processes the product will be dried and is ready for finishing. Solutions from SICK will help you to monitor and control these production steps.
