Measurement and prediction of infinite dilution activity coefficients for C6 hydrocarbons in heavy paraffinic hydrocarbons.

design and construction of a new ebulliometer for measurement of infinite dilution activity coefficients

infinite dilution activity coefficients have been measured for seven binary systems at three different pressures using a newly - designed ebulliometer. the results obtained through these experimental measurements have been compared to literature values for four of the seven binary systems and the calculated deviation has been less than five percent in most cases. having verified the soundness a...

Hydrocarbons and Heavy Metals Pollutants in Aquaculture

1.0 INTRODUCTION The increasing of human population has increased the need for food supply. This with the need for quality fish protein has increased the demand for fish and fish products. The global consumption of fish and derived fish products has generally increased during recent decades (Wim et al., 2007). The cage aquaculture sector has grown very rapidly during the past 20 years and is pr...

Anaerobic Bioconversion of Heavy Hydrocarbons Using Native Consortia

Characterization of C6 to C35 Petroleum Hydrocarbons in Environmental Samples:

1.1 This gas chromatographic method is designed to determine the concentrations in soil and water of petroleum hydrocarbons from nhexane (C6) to n-pentatriacontane (C 35); an approximate boiling point range from 70C to 500C. This includes the gasoline, diesel range, and some portions of heavier fuels and lubricating oils. This method also describes the separation of the petroleum hydrocarbons i...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
