Investment to progress energy efficiency in the pulp and paper industry can help in delivering considerable energy savings, enhanced productivity, and reduced environmental pollution.
FREMONT, CA: Upgrading energy efficiency in the industrial setting is prioritized in most nations because of its magnitude in the quest for energy supply security, increasing economic competitiveness, and dropping greenhouse gas emissions. One of the most high-intensity industries is pulp and paper.
Statistics show that the pulp and paper industry accounts for over 20 % of the total energy consumed by all manufacturing operations in the country. There is also a decline in the demand for a few paper products like newsprint and the energy efficiency developments at various mills.
Conventional paper mills use most of their power in the pulping and drying processes. Nevertheless, the explicit energy consumption in the production results from several factors comprising product mix, plant size, methods used, feedstock quality, plant capacity utilization, technological age of the mill, and climate conditions.
Investment to advance energy effectiveness in the pulp and paper industry can help in delivering considerable energy savings, enhanced productivity, and minimised environmental pollution. A few possibilities to boost energy efficiency include:
● Heat recovery.
● Increased use of biomass fuel.
● Cogeneration.
● Efficient motors.
● Increased recycling of recovered paper.
● Improved efficiency of steam use.
Few methods to increase energy efficiency include:
Enhance Blow-Through Steam Consumption: Firms can improve low-through steam consumption. Few valves leading the flash vapors to the heat exchanger are partially open. The instance generates a loss of steam in the system, increasing the steam consumption in the paper machine.
Replace Vacuum Pumps with Vacuum Blowers: The capability of vacuum pumps is about 40%, Considering that of vacuum blowers is roughly 60 %. The replacement of vacuum pumps with vacuum blowers helps to decrease energy consumption by about 40%.
Fitting Heat Pump or Chiller Heat Pump: Energy can be saved by fixing chiller heat pumps or vapour absorption heat pumps.
Installation of Centralized Compressed Air Generation System: Highest-priced elements of all plant utilities are Compressed air systems. Several systems generally have capabilities in the range of 15 to 25 percent. One way to improve efficiency is by adequately selecting the compressor for an appropriate application.
