Applications[ edit ] Today, the field of paper and chemical engineering is applied to the manufacture of a wide variety of products. The bio chemical industry scope manufactures organic and agrochemicals fertilizers, insecticides, herbicidesoleochemicalsfragrances and flavors, food, feedpharmaceuticalsnutraceuticalschemicalspolymers and power from biological materials.
The resulting products of paper engineering including paper, cardboard, and various paper derivatives are widely used in everyday life.
In addition to being a subset of chemical engineering, the field of paper engineering is closely linked to forest managementproduct recyclingand the mass production of paper — based media.
Mechanical pulping[ edit ] In the process of mechanical pulping, "grinding" and "refining" are the two main methods used to create the pulp. Grinding is the method of pressing logs and chips against a turning stone to produce fibers. Refiner pulping is treating wood chips with chemicals or heat and then crushing the objects between two disks, one or both of which are rotating.
There are four main types of refiner pulping, which includes refiner mechanical pulping, thermo-mechanical pulping, chemi-mechanical pulping, and chemithermomechanical pulping.
However, the paper created is generally weak since it retains the lignin. After the cellulose fibers are separated from the lignin, a pulp is created which can then be treated to create durable paper, boxes, and corrugated cardboard. Chemical pulping can be characterized by two main methods: Sulfate pulping can be performed on a wide range of tree varieties and results in the creation of a strong type of paper.
Conversely, sulfite pulping results in a higher volume of pulp which is easier to bleach and process.
However, sulfate pulping is more widely used since the product is more durable and the chemicals used in the process can be recovered, thus resulting in minimal environmental pollution.
Paper machine The pulp is then processed through an apparatus which renders the pulp as a mesh of fibers. This fiber network is then pressed to remove all water contents, and the paper is subsequently dried to remove all traces of moisture.
Paper After the above processes have been completed, the resulting paper is coated with a minuscule amount of china clay or calcium carbonate to modify the surface, and the paper is then re-sized depending on its intended purpose.
Paper recycling Generally, the material to be recycled first undergoes mechanical or chemical pulping to render it in pulp form. The resulting pulp is then processed in the same way normal pulp is processed; however, original fiber is sometimes added to enhance the quality and appearance of the product.
