Abstract
From hazardous wastes produced in Petroleum Refineries, the most generated in large quantities is oily sludge. The use of gasoline for the extraction and characterization of paraffinic hydrocarbons from oily sludge was realized. The experimental design was applied to realize the extraction while the gas chromatographic method helped in the characterization of the paraffinic hydrocarbons. The results of extraction and characterization showed that the Ratio Solvent/Sludge has positive effect while Temperature and Contact time have negative effects on the effectiveness of the extraction process. 14825 ppm is the highest concentration obtained through experimental conditions of Contact time = 30 min, Temperature = 40°C, and Ratio = 6:1. 2,6,10,14-Tetramethylpentadecane (Pristane) is the compound having the highest concentration (2373 ppm) followed by 2-Methylhexadecane with a concentration of 848 ppm.
Highlights
The remains found at the base of tank and other storage facilities are generally referred as sludge [1] which is constituted of considerable amounts of hydrocarbons, water and solid particles [2]-[4] and of mutagenic, carcinogenic, or poisonous compounds [4]-[7]
Knowing that products like petrolatum are manufactured heavy paraffins, our study is orientated toward the recovery of paraffinic hydrocarbons in oily sludge from Cameroon Petroleum Refining Company
This work have as objectives to bring out the effect of some physical parameters on the recovery of paraffinic hydrocarbons from oily sludge with a fraction of commercialized gasoline used as solvent and to characterize the extracts by identifying and quantifying the compounds that were extracted from the Cameroonian oily sludge
Summary
The remains found at the base of tank and other storage facilities are generally referred as sludge [1] which is constituted of considerable amounts of hydrocarbons, water and solid particles [2]-[4] and of mutagenic, carcinogenic, or poisonous compounds [4]-[7]. As the composition of crude oil varies, that is how the one of the oily sludge varies as well as the one of the hydrocarbon fraction. Great amount of high molecular weight paraffinic hydrocarbons were found in Cameroonian oily sludge [8], [9]. Knowing that products like petrolatum are manufactured heavy paraffins, our study is orientated toward the recovery of paraffinic hydrocarbons in oily sludge from Cameroon Petroleum Refining Company. This work have as objectives to bring out the effect of some physical parameters on the recovery of paraffinic hydrocarbons from oily sludge with a fraction of commercialized gasoline used as solvent and to characterize the extracts by identifying and quantifying the compounds that were extracted from the Cameroonian oily sludge
