In present study wax deposition was studied at 80C using cold finger device. Three crude oil samples were tested in original and demetalized composition for wax deposition. FTIR and GC-MS was used for chemical composition and structural analysis of the obtained wax. Significant difference was observed for wax deposition in original and demetalized crude oil samples. The chemical composition analysis of carbon-hydrogen stretching mode showed a strong absorption between 2850 cm -1, 2916 cm -1 and 2950 cm -1. GC-MS analysis confirmed the pattern of n alkanes with presence of other high molecular weight compounds in wax obtained from crude oil samples. © 2011 IEEE. date: 2011 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84857074096&doi=10.1109%2fNatPC.2011.6136257&partnerID=40&md5=e3a64cfca07b70e916c2f9d79ea57731 id_number: 10.1109/NatPC.2011.6136257 full_text_status: none publication: 2011 National Postgraduate Conference - Energy and Sustainability: Exploring the Innovative Minds, NPC 2011 place_of_pub: Perak refereed: TRUE isbn: 9781457718847 citation: Khan, M.S. and Mukhtar, H. and Kait, C.F.
