EPS has completed numerous energy efficiency projects in diverse industries in North America and internationally. The following are a few examples of our completed projects.
EPS assessed a large textile complex in India and designed, financed and supplied a new caustic soda recover system using triple effect evaporators to recover valuable chemicals from the plant effluent and re-use them. The project reduced chemical costs by over 40% and improved the environment by decreasing the quantity of chemicals being rejected in the wastewater.
EPS assessed a large textile complex in India and designed and supplied a new reverse osmosis water recycling system to recover and re-use water from the wastewater effluent. The new system was financed under a clean technology line of credit.
EPS assessed the operations of two paper mills resulting in the implementation of a new system for recovering heat from a tissue machine exhaust and transferring this heat to the cool incoming air, which was being heated by steam coils. The project resulted in a decrease in steam consumption for tissue machine drying. The new heat recovery system was installed during a two-week plant shutdown. The project was part of a national industrial ESCO demonstration program to demonstrate the innovative business model for decreasing energy costs, improving competitiveness and decreasing greenhouse gas emissions.
EPS analyzed the energy and production performance of a steel re-heat furnace in order to develop a solution to decrease energy costs and increase production capacity. The resulting project involved design and turn-key installation of new furnace pre-heat zone using high velocity gas burners and a highly efficient heat transfer design. The project was installed during a two-week production shutdown.
EPS assessed a large textile complex in India and designed, financed and supplied a wastewater heat recovery system that decreased energy costs and increased production speed. All of the system parameters are monitored on-line and converted into monetary benefits in real-time.
EPS recommended replacement of an old flue gas economizer for a furnace with a new high temperature system that resulted in an increase in combustion air temperatures of 300 degrees F. This resulted in decreased fuel consumption for the furnace operation.
EPS assessed an existing ladle heating system and installed a new hinged cover that eliminated heat loss from the system and decreased gas cost by 70%. The savings were measured and monitored on an on-going basis.
EPS assessed the existing wastewater treatment system at this industrial facility and identified an opportunity for reducing electricity usage for aeration by installing new oxygen measurement in the lagoon tied to a new variable speed drive on the aeration blower. The new system could therefore be set to deliver exactly the necessary quantity of aeration leading to decreased electricity consumption and better process control. The project was part of a national industrial ESCO demonstration program to demonstrate the innovative business model for decreasing energy costs, improving competitiveness and decreasing greenhouse gas emissions.
EPS assessed an existing fume capture fan system and identified potential to replace the fan with a high efficiency design. The new system was installed during a production shutdown and resulted in decreased power consumption (700 kW), decreased maintenance and improved reliability.
