They determined that the gas turbine's air intake system was undersized and pre-filters had an initial resistance that was too high, causing the turbine to be "starved" for air. Koch replaced these filters with a better filter that eliminated the problem. Project Summary Koch Filter Corporation converted the pre-filters on Dow's gas turbine to Koch's Multi Pleat GT-HD Pre- filters. The lower air resistance enabled Dow to realize energy savings of $156,000 annually. Besides the energy savings, Dow was able to extend filter-change life cycle time from 3 months to 6 months, and reduce filter costs by 35%. • Energy Savings $156,000 per year • Investment 35% less than the cost of the original filters • Financial Return Immediate - no additional investment costs were required to produce the savings • Other Benefits Extended filter life, reduced labor costs for change-outs, increased production uptime, and reduced landfill costs Monitoring & Verifying Energy Savings Dow has replaced filters at the new change interval, and has determined that the new filters are performing as designed. Distinguishing Value Koch Filter Corporation responded to Dow's need to decrease energy cost and extend filter life cycle. In addition, Koch has been able to produce subsequent replacement filters in a timely manner, eliminating costly shut-downs of the gas turbine. *>EPA United States Environmental Protection Agency ------- |
