Unlocking Millions in Energy Savings as Easy as Turning a Key
CASE STUDY - Four of Thermal Energy International's (TEI) engineers travelled to the Resolute FP Canada Inc. ("Resolute") pulp and paper mill in Thunder Bay, Ontario to conduct an onsite survey and specification process to properly size and replace the facility's existing mechanical traps with high-efficiency GEMTM Steam Traps.
Zero Line Control for the Dryer Hood
Summary
To minimize drying energy costs this paper proposes optimizing dryer section hood and air system efficiency via the use of zero pressure line control combined with humidity control to maintain maximum exhaust humidity.

Ontario, Canada:Commissioned in 2011, Precision Energy Services, Inc. (PES) of Hayden, Idaho, supplied the first sludge-to-energy system to Atlantic Packaging's 111 plant location.
Did you know that pulp mills produce lots of bioenergy?
UPM has four pulp mills that produce pulp from pine, spruce and birch in Finland and from eucalyptus in Uruguay.
Is separator tank size and design critical to the proper operation of dryer cans?
Absolutely! Undersized separator tanks generally result in high velocities of steam and condensate flow through the inlet separator nozzle, through the shell of tank, and through the outlet blow-through steam nozzle.
Do high-efficiency thermocompressors save steam?
A high-efficiency thermocompressor will offer an operating cost advantage if the source of the motive steam bypasses a cogeneration turbine or if the source of motive steam is produced on a high-pressure boiler separate from the source of low-pressure steam.
Energy Optimization Package for Yankee Hoods
Energy optimization is priority today in all sectors of fabrication including tissue and towel. The Yankee drying system on the tissue machine represents an interesting savings opportunity since both natural gas and steam are utilized therefore significantly impacting energy costs.
Yankee Hood: Energy Optimization Study
In the last article we looked at optimization strategies for the energy consumption on a Yankee Dryer system, particularily the natural gas consumption in the Yankee Hood versus the steam in the Yankee cylinder.
Typical Yankee Drying Performance Analysis
Yankee air systems are energy intensive and should routinely be checked to ensure that they run at an optimal level. A proper hood balance ensures maximum thermal efficiency (i.e. BTU (fuel) per ton of paper).
Energy Optimization on Yankee Dryer Hoods: Saving on Gas and Steam
Energy savings are of prime concern nowadays and interesting optimization opportunities exist for tissue mills, particularily on the Yankee dryer.
