Research on the Low Efficiency Separation of Typical High Sulfur Gas Well Separators
In the later stage of development and production of natural gas wells,gas field water and small particles are usually produced,and separation devices are used for initial treatment.Due to the in-ability to achieve complete separation of each phase in the separation device,the separation effect is poor,which can have adverse effects on the smooth operation of downstream devices,and may cause serious economic losses.Based on the analysis of the low-efficiency separation of a high-sulfur gas well separator by field test,it is found that the flow rate at the inlet of the separator increases,the stable space is insufficient,internal droplet entrainment is serious,and the separation effect is poor.The fol-lowing measures are put forward to solve the problem of low-efficiency separation of high sulfur gas well separators:the inlet devices are correctly selected,and the dynamic pressure energy of the inlet nozzle is verified.Ishii-Grolmes Criteria is used to estimate the initial gas phase entrainment velocity of the horizontal gas-liquid separator.The installation requirements of the mist eliminator and the flooding point are checked.Non-welded internal components are selected,differential pressure monitoring for internal components is set up,and regular cleaning procedures are established.Mist eliminator in prima-ry gas-liquid separator at the wellhead can be eliminated to simplify design and reduce maintenance.The above measures have certain guiding significance for the design and production process management of high sulfur gas well separators.
