Eastman Receives Energy Efficiency Awards for 22nd Consecutive Year
May 6, 2015 /3BL Media/ - Eastman Chemical Company was one of 20 American Chemistry Council (ACC) members honored at the annual ACC Responsible Care® Conference and Expo for implementing energy-efficiency improvements in 2014.
Eastman received 10 of the 59 awards presented for outstanding projects, marking the 22nd consecutive year the company has earned energy efficiency awards from ACC.
According to ACC, total annual energy savings of all winning projects was seven trillion BTUs, enough to power all the homes in a city the size of Erie, Pennsylvania for one year. Combined, Eastman’s winning projects save enough energy to power more than 1800 homes and eliminate greenhouse gas emissions from over 2,700 cars.
“At Eastman, we continuously look for opportunities to drive energy improvements. These winning projects exhibit innovative solutions, including implementation of new equipment, creative process redesign, and operational changes. All of this great work is attributed to the commitment and focus on sustainability of our employees,” said Sharon Nolen, Worldwide Energy Manager.
Eastman’s Tennessee Operations in Kingsport, Tenn., received awards for the following projects:
- 300# Flash System – Installation of a flash system that utilized 600 psig condensate from columns eliminated sending 600 psig steam through valves to produce 300 psig steam.
- B-276 Warehouse Lighting - Replacing 452 watt fluorescent lights with LED lights with occupancy sensors not only reduced energy use but also provided a work area for employees with improved visibility.
- B-280/B-310 Energy Reduction – An energy reduction effort involving not only specific projects but also employee involvement resulted in an energy reduction of 26% from the previous year.
- Azeo Energy Optimization – To reduce energy consumption, a process control strategy was developed to optimize low and medium pressure steam use on distillation columns.
- Weak Mixed Acid Target Change – By optimizing the concentration of an acid feed stream, downstream acid reprocessing was reduced.
- Group 13 Vacuum Pumps – Less efficient steam jets were replaced with liquid ring vacuum pumps which eliminated the loss of steam condensate and resulted in lower energy use.
Eastman’s Indian Orchard Operations in Springfield, Mass., received awards for the following projects:
- Hot Water Recycle Project – Cooling water which was previously being sent to the sewer is now being recycled for use as feed to the washing process.
- RB Condensate Coil Heat Recovery – A reduction in dryer steam consumption was achieved by installing a new heat recovery system designed to re-use waste condensate which was previously being sent to the sewer.
Eastman’s Chestertown Operations in Chestertown, Maryland received an award for the following project:
- Thermal Efficiency Improvements by Conversion to Propane Fuel - Steam generation units were converted to propane from #6 fuel oil, burners were replaced, and a new burner management system was installed on the larger, primary steam boiler which improved the efficiency. The plant retired two of the older, less efficient thermal oil furnaces and replaced them with a new more efficient unit.
Eastman’s joint venture partner located at its Kingsport, Tenn. site, Primester, received an award for the following project:
- Heat Integration – In Primester’s Acid Recovery process, a new heat interchanger was installed upstream of a cooling water condenser to capture the extra heat in a hot process stream and preheat the feed to a primary distillation column, thereby reducing total steam used to heat the process.
Earlier this year, Eastman was recognized with the 2015 ENERGY STAR® Partner of the Year Sustained Excellence award for continued leadership in superior energy management by the U.S. Environmental Protection Agency (EPA). Winning its fourth consecutive award, Eastman is the only chemical company to be recognized by ENERGY STAR more than once.
