8807GC® Portable Gas Chromatograph

Emissions & Process Testing

THC, VOC, aromatics, ethylene oxide, solvents, acetone

PCF’s 8807GC® Portable Gas Chromatograph is mainly intended for measurements of reactive hydrocarbons in ambient air and/or source gas by subtracting from the total concentration of hydrocarbons to the methane fraction. The analyser however can easily be reconfigured for specific hydrocarbon continuous monitoring. A sample pump on the back of the pneumatic circuit fills a calibrated capillary, whose content is injected via a 10 port rotation valve into a chromatography column filled with PQS or a most suitable substrate that allows separation of methane fraction from the total hydrocarbons. A microprocessor manages all functions relative to analytical sequences as well as data management, calibration and purge sequences. The software controls preconditioning, analytical sequences and alarm status. The instrument can easily be set for specific hydrocarbons (up to a maximum of eight species) by a simple upgrade of the firmware through the front panel interface.

NMHC	10 to 500 ppm	0.02 ppm

The separation of methane fraction is based on the chromatographic method. Once specified the CH4 is measured separately and then subtracted from Total Hydrocarbons concentrations. The measuring sequences are managed by the built-in 10 port rotation valves enabling sequential measurement of THC, CH4 and NMHC. A zero calibration cycle triggered automatically before each measuring cycle guarantees a high signal stability and efficient drift compensation.

The same technology can be adapted to specific VOCs stack emissions monitoring and process control needs. The coupling of gas chromatography separation with state of the art FID detector allows accurate and reliable measurement of Benzene (C6H6), Ethylene (C2H4), Propylene (C3H6), Styrene (C8H8), Acetone (C3H6O), Formaldehyde (CH2O) and many others VOCs.

8807GC® Portable Gas Chromatograph

THC, NMHC, CH4, Benzene (C6H6), Ethylene (C2H4), Propylene (C3H6), Styrene (C8H8), Acetone (C3H6O), Formaldehyde (CH2O) and many others VOCs

Typical Applications

Process gas and emissions monitoring in combustion plants, boilers, syngas, biogas, waste recycling facilities (Waste to Energy) and associated filtration systems are typical applications for the 8807GC® Portable Gas Chromatograph.

Landfills, Biogas Plants, Incinerators

“Landfilling” is the main method for disposal of municipal and household solid wastes or refuses in Australia. Although maintained in an oxygen-free environment and relatively dry conditions, landfill waste produces significant amounts of landfill gas (mostly methane). The 8807GC® Portable Gas Chromatograph enables process and air pollution emissions monitoring from solid waste landfills. Landfills operations require the control of Benzene (C6H6), Ethylene (C2H4), Propylene (C3H6), Styrene (C8H8), Acetone (C3H6O), Formaldehyde (CH2O) and many others VOCs emitted.

Landfills, Biogas Plants, Incinerators, wastewater treatment plant, refineries requires detailed monitoring of the process conditions. Therefore, it is recommended to monitor both the volume of gas produced and the gas composition. With regard to process monitoring, a change in either gas production or gas composition can be an indicator of process imbalance.

THC, NMHC and CH4 measured during the methanation process give a good overall view of the performance of the degradation process and bacterial activity. A decrease in methane content can be a first sign of organic overload, provided that the feedstock mix has not recently changed.

Simultaneous real-time monitoring of THC, NMHC and CH4 empowers process automation (i.e. operation of scrubbers).

THC, NMHC and CH4 Continuous Stack Emissions Monitoring required for environmental compliance

Specific catalytic separation developed for Benzene (C6H6), Ethylene (C2H4), Propylene (C3H6), Styrene (C8H8), Acetone (C3H6O), Formaldehyde (CH2O) and many others VOCs

Thermal Oxidiser

Thermal oxidisers are typically used to eliminate HAPs and VOCs from industrial air streams . These pollutants are generally hydrocarbon based and when destroyed via thermal combustion they are chemically oxidized to form CO2 and H2O. The temperature needs to be high enough to ignite the waste gas. Most organic compounds ignite at the temperature between 590°C and 650°C. Accuracy and high reliability in harsh conditions of operations makes the 8807GC® Portable Gas Chromatograph a powerful optimisation tool for thermal oxidisers. GTC and thermal oxidisers reduce the emissions of pollutants such as Benzene (C6H6), Ethylene (C2H4), Propylene (C3H6), Styrene (C8H8), Acetone (C3H6O), Formaldehyde (CH2O) and many others VOCs. Monitoring of THC, NMHC and CH4 upstream of the Thermal Oxidiser enables optimal process optimisation.
