GAS SEPARATOR IMPROVEMENTS

摘要

A gas separator has a separator member that rotates with a shaft for separation of fluid components. A flow divider directs more dense fluid to the pump and less dense fluid into an annulus surrounding the pump. An impeller is located within the flow divider for urging fluid out of a downstream gas exit port. A single large gas exit port is used and may be combined with use of a single large fluid inlet. An auger may be located within the rotary separator member. Holes may be located in the sidewall of the rotary member or chamber. The holes are preferably located in a helical pattern above and adjacent the flights of the auger or are in vertical colum ns adjacent the baffles. The chamber may have a cylindrical or tapered profile. Alternatively, a series of sub-chambers may be used, each having a small er radius than the preceding, upstream sub-chambers.
