Continuous Emissions Monitoring (CEM) Systems
VIG has designed, built, and assisted in configuring many Continuous Emissions Monitoring Systems (CEMS) for several different applications.
Take a look at these CEM systems applications: [ 1 ][ 2 ][ 3 ][ 4 ][ 5 ][ 6 ][ 7 ][ 8 ][ 9 ][ 10 ][ 11 ]
|
System 1 |
This system incorporates a Model 20 Total Hydrocarbon Analyzer, a custom made control panel, chart recorder and all interconnecting wiring. The system was installed in a cabinet with a clear front door and casters so that it could be easily moved from location to location. |

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 and 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 (PLC) & 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. |

System 3 |
This system was designed to measure the volume of oil present on small radiator cores for a major automobile parts manufacturer. The part is heated in the environmental chamber on the left so that the oil on the part is burned and turned into gas. The analyzer measures the gas and sends the signal to the computer system for analysis. The computer then calculates the volume of oil present. |

|
|
System 4 |
This system incorporates two VIG hydrocarbon analyzers, a multi-point sequencer and a combustion / zero air generator. All sample line temperatures a controlled by the custom sequencer along with the automatic sequencing functions. The zero air generator provides bottle free zero air and clean combustion air. |

|
System 5 |
This system incorporates two VIG dual channel hydrocarbon analyzers along with a flow control panel and all data logging equipment. The system was mounted in a rugged Anvil case with swivel castors for ease of movement between multiple locations. |
 |
| |
|
|
System 6 |
VIG Industries has been working with a major paint booth manufacturer to design systems to measure their abatement efficiency. These systems work on a new patented technology not using standard carbon, which can be regenerated by using warm air rather than steam. |

System 7 |
These systems were installed in a power plant. They were designed to replace two existing, outdated systems. Each package included a sample conditioner, flow control panel, NOX analyzer, O2 analyzer, integrated touch screen and PLC to operate all controls, and a communication and reporting software system. All wiring is located under a removable side panel for easy access. |

System 8 |
This system was designed to control a VOC (volatile organic compounds) destruction system. It includes a VIG Model 20 Hydrocarbon Analyzer to measure breakthrough of VOCs.
|
|
|
|
| |
|
|
System 9 |
This system was designed to control a carbon adsorption system at Honeywell in Torrance, California.
|
| |
|
|
System 10 |
This system was designed for a power plant in Huntington Beach, California. |

System 11 |
The PSC3 is a CEM system for PCS recycling facility in Inglewood, California designed to monitor total hydrocarbons in the process between carbon vessels and at the stack. The system configuration is based on the VIG Industries dual channel total hydrocarbon analyzer Model-20/2, a programmable sequencer, calibration mode select, a paperless data recorder, and control alarms. All equipment is housed in the stand alone 19" rack mounting cabinet with a security glass front and solid rear doors. |
