BACKGROUND AND DISCUSSION
Currently, two Caterpillar generator engines generate most of the electricity used to power the Water Pollution Control Plant (WPCP). These generator engines are primarily fueled by biogas provided by anerobic digesters, landfill gas recovery system and an air blended natural gas system. To ensure these engines operate optimally, the WPCP uses the Power Generator Facility (PGF) to dehumidify the biogas fuel which reduces contamination of the generator engine oil, increases engine life, and consequently reduces the costs derived from the frequency of engine overhauls and loss of power generation downtime. Within the PGF is a biogas dryer which performs the dehumidifying action. The existing biogas dryer was installed in 2007 and needs replacement due to frequent breakdowns causing insufficient biogas fuel drying. Insufficient removal of moisture reduces the methane content in the fuel available to the generators. The moisture in biogas can also combine with other contaminants ...
