Process GC for VOC analysis for petrochemical applications
Sep 30 2020 Read 495 Times
Chromatotec has developed an enhanced headspace sampling system designed to extract representative compounds from the liquid phase. The vapourised sample is preconcentrated using a trap to achieve quantification of VOCs at trace and ultratrace levels (ppb and/or ppm). Then, it is injected automatically and in continuous mode into the airmoVOC WMS auto-GC-FID analyser. This solution has been deployed in refineries and petrochemical industries for the quantification of BTEX present in oily wastewater because of their water solubility and polarity. These contaminants may reach groundwater, leading to important health and environmental issues. The airmoVOC WMS enables operators to comply with wastewater discharge regulations from environmental protection agencies.
This fully automatic system does not require a trained technician to operate it. The detector can be operated continuously thanks to the integrated generators. The internal calibration system provides automatic data validation, only power supply and sampling lines need any operation to obtain reliable and representative analysis without molecular loss.
