Identification and measurement of petroleum precipitates
نویسندگان
چکیده
A number of procedures to identify and measure the precipitates that result from petroleum fluids are presented. The Ž . fractions considered in this study include those in the categories of asphaltenes, resins, saturates paraffinrwax , aromatics, inorganic minerals and diamondoids. A combination of deposition techniques, separation by centrifuge, filtration, gas Ž . chromatography, gel-permeation chromatography, and SARA LC-HPLC separations, and a number of other techniques are utilized to identify each fraction and quantify their concentrations. These procedures provide an understanding of the overall behavior of the species that precipitate as well as of the interactions among them. The results of such analysis are the cornerstone of any predictive and preventive measures for heavy organics deposition from petroleum fluids. q 2000 Elsevier Science B.V. All rights reserved.
