Murban crude

If needed, increased sensitivity can be obtained for trimethylben-zenes, and the range can be extended to include the naphthalenes if the equilibrated gas is analyzed by temperature-programmed gas chromatography. Figure 3a shows an isothermal run of hydrocarbons dissolved in seawater from an excess of a Murban crude oil. Figure 3b shows a temperature-programmed run on a similar water sample.

Table V shows the concentrations of individual low-molecular-weight hydrocarbons in the water samples collected. The highest total concentration was 60/u,g/L (ppb) in the 5-ft water sample collected after the first Murban spill (39° API gravity crude). Total hydrocarbon concentrations in the other four samples ranged from 2 to 16 ppb. The difference is probably due to higher winds at the time of the first Murban spill.

Zakum, Murban, and Tia Juana crudes/water systems, that interfacial shear viscosity, decreased with increased pH, and Tig decreased with increase in electrolyte NaCl. Also, T g increased over time. This did not correlate with the asphaltenes content.
