Abstract

Characterization and chemical analysis is a necessary step in identifying the chemical constituents of the heavy unconventional oil (Bitumen) which will definitely proffer a way forward for the production, modification and refining of the heavy oil. This study presents naphthenic acidic content of four different bitumen deposit location which is considered to be the initial step before the production with respect to design and operational condition and specification of the refinery. Acidity of crude causes wearing of equipment, deactivation of catalyst as a result of coke formation, hence it need to be determined in order to predict the cost of production, refining, modification and upgrading of the heavy oil couple with the pseudo-component of range of hydrocarbon mixture in the heavy component, a high temperature simulated distillation in accordance to the ASTM procedure was modelled in this study in order to simulate the true atmospheric boiling point of all the pseudo-components in the unconventional oil using gas chromatography flame ionization detector (GCFID) so as to ascertain the economic viability of processing the Ondo state bitumen deposit. The results of the total acidic number of the bitumen samples ranges from (1.7---2.0 mg/g) and this serves as an indication according to ASTM standard that the bitumen deposit has high naphthenic acid content which will entail high cost of processing, refining, modification and upgrading of the Nigeria bitumen deposit
