Gas separators-dispersers are intended for stable operation of submersible centrifugal pumps in pumping-out of reservoir fluids with high content of free gas.
Gas separators-dispersers are installed at a pump intake instead of gas separators in wells with specifically high gas-oil ratio, where the gas separator does not secure stable operation of a submersible centrifugal pump.
Friction pairs of radial thrust bearings in gas separators-dispersers are made of hard alloy.
A gas separator-disperser working principle is based on using centrifugal force to remove free gas. Gas is removed in annular space without vapor locking in the pump, leading to stable unit operation and increase of mean time between failures.
Advantages and design features
Friction pairs of radial thrust bearings in gas separators-dispersers are made of hard alloy. End elements and protection sleeves are made of corrosion-resistant steel to improve hydro abrasive wear. Wet end elements are made of corrosion-resistant steel and cast iron of Ni-resist type.
Gas separators-dispersers are complete with shafts made of corrosion-resistant steel 05Х16Н4Д2Б and alloy Monel К-500, Inconel-718. As requested by the customer, gas separators can be fitted with shafts made of different steel types and alloys.
