ABSTRACT:
An inline well fluid separator is movable for pigging operations. The separator assembly has a housing with an inlet port and an outlet port. A separation unit is carried within the housing. The separation unit has an operational position in alignment with the ports to cause well fluid to flow through the separation unit. The separation unit will move to a storage position within the housing outside of the flow path to enable a pipeline pig to pass.
