الملخص الإنجليزي

Water in oil emulsion occur at many stages in the production and treatment of crude oil.

The emulsion stability results from the presence of interfacial barrier preventing coalescence of the dispersed water droplets.

This is due to the presence of polar components such as asphaltenes, resins, wax, and naphthenic acids in the crude oil.

Therefore, before transporting or refining the oil, it is essential to separate the water for economic and operational reasons.

In the present work five demulsifies were used (RP6000, Chimec2439, PAA> LAS and HAS) for AWlasrah water in oil emulsion.

The experimental work was performed under 65°C emulsion temperature and water content 30 % vol (3 % wt NaCl).The parameters studied on water separation process were : 1- Demulsified dose (10, 20, 30, 40, 50, 60, 70 and 80) ppm.

2- Separation time (5, 10, 15, 30, 60, 90 and 120) min.

3-Types of demulsifies (RP6000, Chimec2439, PAA, LAS and HAS).

4- Alcohols Concentration {25 %, 50 %, 75 %, and 100 %) adds into commercial demulsifies (RP6000 and Chimec2439).

The results obtained with prepared demulsifies (HAS, LAS and PAA) were (90 %, 88.3% and 75%), respectively.

Two types of commercial demulsifies were also used (RP6000 and Chimec2439), which gave water separation efficiency (87.5 % aid 72.2 %), respectively.

Two types of alcohols were used as modifier agents to enhance the performance of demulsifies at different mixing percentages.

Methanol and ethanol were used for this purpose and the optimum mixing percentage of alcohols was at concentration of (25 %).

Methanol gave higher water separation than ethanol, (61 %) when use RP6000, (56.6 %) when use Chemic2439.
