Fluidic Delivery Line for Naphtha Detection

  • Author / Creator

  • Naphtha that consists of low molecular weight aliphatic and aromatics and other low molecular weight iso-paraffins and naphthenes is used as a diluent in processing of bitumen from oil sands. During oil sands processing, almost all of the naphtha is recovered. However, a small fraction, viz. <1%, is lost to tailings waste and is incorporated into mature fine tailings. Presently, a sample of mature fine tailings is collected and transported to laboratory every 6 hours to monitor its naphtha content using Gas Chromatography Mass Spectrometry. This method of detecting naphtha is time consuming, expensive and requires trained personnel. Above all, it does not allow for real-time detection. To meet the demand of real-time naphtha detection in mature fine tailings, an approach for design and development of fluidic delivery line as processing unit for naphtha sensor has been made. In this study, a compact and portable fluidic delivery system is devised that combines the filtration unit, the pumping system and the heating system in a static cell for Naphtha detection. The filtration unit makes the processed water devoid of impurities like clay particles and sand. A droplet system is used to pour the filtered sample on a copper sheet that serves as hot plate for the heating system. The vaporized sample is pulled out and delivered to the micro cantilever that detects naphtha. A miniaturized design using a microfluidic filtration unit and a liquid-vapor separation chip is also proposed. The proposed fluidic delivery line can be used for any available liquid.
