Abstract


The problem of heavy organic deposition in the production and processing of crude oil in the oil and gas industries is globally known. There had been work done to minimize the problem such as changes in temperature, pressure and composition. This study was designed to investigate how different ratios (v/v) of nC5:nC6; nC5:nC7; nC5:nC8; nC6:nC7; nC6:nC8and nC7:nC8 affect controlled deposition. The results indicated varying optional (v/v) ratios for the different binary mixtures of Afiesere crude oil; that nC5: nC6 binary mixture ratios have a weight % heavy organic precipitation range of 1.02 to 2.42; nC5: nC7 binary mixture ratios have a weight % heavy organic precipitation range of 0.15 to 1.88; nC5: nC8 binary mixture ratios weight % heavy organic precipitation range of 0.16 to 1.88; nC6: nC7 weight % heavy organic precipitation range of 0.85 to 1.19; nC6: nC8 weight % heavy organic precipitation range of 0.60 to 1.19 and nC7: nC8 binary mixture ratios weight % heavy organic precipitation range of 0.54 to 0.93. Application of the output from this study may minimize deposition problem in the production industries.
