  • TITLE: Experimental Investigation of Fuel Quality and Contaminant Materials from Liquefied Petroleum Fuel

    AUTHORS: Jae-Kon Kim, Kyong-Il Min, Eui Soon Yim

    KEYWORDS: LPG (Liquefied Petroleum Gas), Residue Oil, Plasticizer

    JOURNAL NAME: Engineering, Vol.6 No.10, September 15, 2014

    ABSTRACT: In this study, the quality characteristics and residue analysis in circulated LPG fuel were investigated experimentally in Korea. Quality characteristics in circulated LPG fuel were examined with samples of LPG in the supply chain (refinery, petrochemical, and imported LPG), transport, gas stations, and vehicles. The experimental results showed that quality of all circulated LPG was well within the quality standard guideline of LPG in Korea. Especially, it has shown average 13 wt ppm in sulfur content over the full circulated LPG. The residue samples in LPG fuel were extracted on 2 L scale with acetonitrile and analyzed by gas chromatography-mass spectrometry (GC-MS). The components of residues in LPG were composed of 62 organic chemicals with C3 ~ C28 and the main ingredients of residue were plasticizers ((di-octyl phalate (DOP), di-octyl adiphate (DOA) etc.), lubricant oil and amine compounds. It was also showed that mass of residue in vehicles was increasing compared with supply (refinery, petrochemical, and imported LPG). It was presumed that this residue had been originated from automotive LPG fuel, vehicle components, and lubricant oil in infrastructure.
