Abstract
Water in oil emulsion occurs at many stages in the production and treatment of
crude oil. In the present work three demulsifiers were used (RP6000, Chimec2439 and
PAA) for dehydration (desalting) of Al-Basrah water in oil emulsion. The
experimental work was performed under constant temperature 65oC and water content
30%vol. (3%wt.NaCl). The parameters studied: demulsifier dose (10, 20, 30,
40,50,60,70 and 80) ppm, separation time (5, 10, 15, 30, 60, 90 and 120) min and types
of demulsifiers (RP6000 Chimec2439 and PAA). The dehydration efficiency with
prepared demulsifier (PAA) was (75%). Two types of commercial demulifiers were
also used (RP6000 and Chimec2439), which gave water separation efficiency (87.5%
and 72.2%), respectively. pH, Salt content, remains of water content and density were
estimated. The least density of the desalted crude obtained was (0.874 gm/cm3) at (80)
ppm of RP6000.
