Pulp and Paper Industry: Incomplete without Engineers

Pulp and Paper Industry: Incomplete without Engineers

Manufacturing Technology Insights | Wednesday, November 17, 2021

When it comes to engineering, the pulp and paper industry is rarely mentioned. Engineers, on the other hand, are critical in this industry. Without engineers, the industry would cease to exist, and the world as we know it would undergo significant changes.

FREMONT, CA: Globally, the pulp and paper business is significant. Without engineers, it would disintegrate. They design and manufacture the majority of the equipment and processes used in this business. This industry offers chances in various engineering specialties and provides an intriguing career path for those who choose to join.

Paper production entails several procedures. This means that an engineer is accountable for a great deal in the pulp and paper business. Repeating the process: an engineer would maintain all equipment used in the papermaking process. This may entail detecting faulty equipment, devising preventative maintenance schedules, or conducting a root cause study if equipment fails. If a single piece of equipment fails, the papermaking process comes to a grinding halt.

Engineers would also be responsible for any equipment supporting but not directly involved in the papermaking process, such as chemical tanks. This would entail routine maintenance and corrosion control. Choosing the operating parameters for a process is a task for an engineer. These parameters must be chosen to create the greatest amount of paper possible, most cost-effectively and safely possible. These factors may include the pace at which pulp enters the process, the steam pressure and temperature, the temperature of the rollers, chemical concentrations, and recycle loop flow rates.

An engineer can boost the efficiency of the papermaking process by increasing production or minimizing wastage. For instance, the rollers that separate the water from the fibers could be heated higher to remove more water. Process modifications may involve the addition of new equipment or recycling loops. Chemical management is a subject that engineers frequently deal with in the pulp and paper industry. Chemicals are used to treat wood chips and bleach paper, among other things. To accomplish this, engineers must select suitable chemicals. The incorrect chemicals can alter the color of the paper, weaken it, or make it hazardous.

The pulp and paper sector is heavily reliant on waste treatment. Water and chemicals used in the papermaking process must be disposed of appropriately, and the water is tainted and must be treated before disposal. Water treatment processes include clarifying, which eliminates particulates; biological treatment, which removes organic matter; and chemical treatment, which removes pollutants from the water.

Additionally, an engineer may be in charge of the design of control systems. For example, these systems shut down the papermaking process if it deviates from safe operating norms. These control systems are employed to ensure the safety of persons and property.
