Here's How Pulp and Paper Manufacturers Can Save Energy

By Manufacturing Technology Insights | Tuesday, January 21, 2020

Investment to advance energy efficiency in the pulp and paper industry can help in delivering considerable energy savings, enhanced productivity, and reduced environmental pollution.

FREMONT, CA: Advancing energy efficiency in the industrial setting is being prioritized in most nations because of its magnitude in the quest for energy supply security, increasing economic competitiveness, and in dropping greenhouse gas emissions. One of the most energy-intensive industries is pulp and paper.

According to statistics, the pulp and paper industry accounts for over 20 percent of the total energy consumed by all manufacturing operations in the country. There is also a decline reflecting changes in the demand for a few paper products like newsprint along with the energy efficiency developments at various mills. 

Conventional paper mills utilize most of their power in the pulping and drying processes. Still, the explicit energy consumption in the production is a result of several factors comprising product mix, plant size, methods used, feedstock quality, plant capacity utilization, technical age of the mill, and climate conditions. 

Investment to advance energy efficiency in the pulp and paper industry can help in delivering considerable energy savings, enhanced productivity, and reduced environmental pollution. A few opportunities to boost energy efficiency include heat recovery, increased use of biomass fuel, cogeneration, efficient motors, increased recycling of recovered paper, and improved efficiency of steam use.

Top Industry Safety Solution CompaniesSome of the ways to increase energy efficiency include:

Enhance Blow-Through Steam Consumption: Firms can optimize low-through steam consumption. Some valves leading the flash vapors to the heat exchanger are partly open. The instance creates a loss of steam in the system, thus increasing the steam consumption in the paper machine.

Substitute Vacuum Pumps with Vacuum Blowers: The competence of vacuum pumps is about 40 percent, whereas that of vacuum blowers is roughly 60 percent. The substitution of vacuum pumps with vacuum blowers helps in reducing energy consumption by about 40 percent.

Installation of Heat Pump or Chiller Heat Pump: Energy can be saved by installing chiller heat pumps or vapor absorption heat pumps.

Installation of Centralized Compressed Air Generation System: Compressed air systems are the most expensive elements of all plant utilities. Most systems usually have capabilities in the range of 15 to 25 percent. One way to improve efficiency is by the proper selection of the compressor for an appropriate application.
