CHEVRON RESEARCH AND TECHNOLOGY COMPANY <br /> ANALYTICAL SCIENCES UNIT PROJECT SUMMARY <br /> Project No. 1998.0138 Requested by D. L. Lapporte <br /> Date Initiated 10129198 Location Chevron Pipe Line Co. <br /> Date Completed l 1118198 4000 Executive Parkway <br /> CRTC Charge Code YWTT107094 San Ramon,CA 94583 <br /> Phone 842-5718 <br /> i <br /> Project Description. Analyze a hydrocarbon sample labeled MWZ=SP from Chevron Pipe Line's Vernalis <br /> pump station. Identify the mature of the product. A water sample, MW/Y-SP-W, was provided for backup but <br /> not analyzed. <br /> �'Li2"f5 %-•�-.air �71�t..' -I <br /> �f�•s <br /> r <br /> Results: Sample MWXSP is an evaporated crude oil. The chromatogram is typical of many California <br /> San Joaquin Valley crudes in that it has no apparent normal paraffins, several distinct isoprenoid <br /> paraffins, and a concentration of steraneltriterpane biomarker peaks in the C27-C34 region. <br /> The chromatogram shows no evidence for the presence of any diesel fuel or lube oil in the sample. if <br /> small amounts of these products were present they could not easily be distinguished from the crude. <br /> Analytical Approach: The sample was analyzed by gas chromatography using a flame ionization <br /> detector to determine the hydrocarbon composition. <br /> Analyzed by: N.
