  • TECHNICAL SUMMARY OF OIL GAS PRODUCED WATER

    Hydrocyclones generate spinning motion of the fluid that creates centrifugal force to push heavier water outward and lighter oil into the middle core of the cones. The water continues down and exits out the tapered end. The improved gravity effect provides a higher rate of separation. The oil removal efficiency is higher with multi cone (Figure 4)

    The hydrocyclone used tended to reject short fibres. Other types of hydrocyclones tend to reject long fibres. Fibre fractionation in terms of coarseness and fibre length was affected by the feed flowrate to the hydrocyclone and by consistency.
