Fluidic delivery system for in-situ naphtha detection

Abstract A fluidic delivery system that operates, as processing unit for naphtha sensor, has been developed to detect naphtha. It is a mixture of varied hydrocarbons, which constitute less than 1% seepage in the tailings waste that further incorporates into Mature Fine Tailings. Presently, a sample of mature fine tailings is collected and analyzed using Gas Chromatography Mass Spectrometry every 6 h to monitor its naphtha content. This conventional method of detecting naphtha is time consuming, expensive and requires trained personnel. Furthermore, it does not allow for real-time detection. To meet the demand of real-time naphtha detection in mature fine tailings, efforts were made to design and develop fluidic delivery line as processing unit for naphtha sensor. This paper presents a portable monitoring system, which would facilitate in-situ naphtha detection, and reduced manual labor, cost, among others. This prototype combines filtration unit, pumping system, heating unit and vapor storage for a compact and portable delivery system of the feed obtained from Oil Sands Tailings. The device runs in continuous mode and bears inlet tubing that can be used to draw feed into the system at any source where naphtha is to be detected.
