OILY WATER TREATMENTS FOR SOUTHERN IRAQI OIL FIELDS

  The oil drilling operations create large quantities of contaminated water known as “Produced Water” (PW), or water that is produced from the well. An experimental investigation was conducted using 1litter stainless steel autoclave to treat the oily water produced from North Rumaila and Zubair oil fields. The first approach was a pretreatment to remove solid particles using sedimentation with and without flocculation. The second approach included studied the effect of pH, pressure, temperature, salinity, operation time, outlet time and RPM.

ENHANCEMENT OF MASS TRANSFER USING ROTATING CYLINDER PROMOTERS

 The aim of present work is to determine experimentally the degree of mass transfer enhancement of dissolved oxygen using turbulent promoters of longitudinal leg extensions constructed on Rotating Cylinder Electrode (RCE) made of brass.The limiting current density (LCD) was evaluated under turbulent flow conditions at three different temperatures 35, 45, and 55 C. The experimental runs were carried out in 0.1 N NaCl salt solution of pH = 6 using a rotational velocity range from 200 – 1000 rpm.

INFLUENCE OF SOME ADDITIVES ON THE EFFECINCY OF VISCOSITY INDEX IMPROVER FOR BASE LUBRICATING OILS

The effects of three different additives formulations which are Lubrizol 21001,HiTEC 8722B and HiTEC 340 on the efficiency of viscosit y index improver (VII) namely Olefin Copolymer of three base lubricating oils 40, 60 and 150 stock at four temperatures 40, 60, 80 and 100o C were investigated.The base oils’ blends were prepared with a concentration range of 2-10 wt% from additives and olefin copolymer (OCP).
