System 2
This CEM system includes a Model 200/1 Methane / Non methane FID Hydrocarbon Analyzer, a Model 300/2 CO / CO2 NDIR Analyzer, custom built 14 point sequencer, combustion & zero air generator, hydrogen generator, external sample pump, approximately 5000 feet of Teflon sample tubing, monitoring point vaults mounted in the concrete, monitoring point filters, Allen Bradley Programmable Logic Controller & programming, Pentium II PC with custom data acquisition software with graphical user interface, Sensaphone 2000 alarm reporter (fax, e-mail, voice, pager), color printer, Uninterruptible Power Supply, 5HP gas evacuation blower, and telephone.
This system is designed to automatically switch between 14 sample points every 7 minutes and measure the methane and the non methane hydrocarbon at each point. If the concentration is within acceptable limits the system automatically switches to the next point and records the data. If the concentration is not within acceptable limits, the system will alarm, send faxes, pages, phone calls and e-mails to appropriate personnel, turn on the gas evacuation blower, and record all alarms. After two hours the system will resample the point and move to the next one if the concentration has dropped. The system can also be controlled and the data can be retrieved from a remote computer anywhere over standard telephone lines.
