PLANT FOR SEPARATION OF AIR FROM FLUID TRANSFERRED IN PIPELINE Russian patent published in 2012 - IPC B01D19/00 

FIELD: process engineering.

SUBSTANCE: invention may be used for air and air-gas mix separation from oil products. Proposed plant comprises vertical housing 1 with its cover 2 fitted with air discharge branch pipe. Housing 1 is divided by perforated web 4 into two chambers. Inlet and outlet branch pipes, 6, 7 for connection to pipeline are arranged under said web. Inlet branch pipe 6 is arranged tangentially. Preset fluid level stabiliser with float sensitive element 8 is arranged above said web 4. Said stabiliser is made up of cylindrical adapter with inner stepped chamber. Smaller-diameter chamber has radial channels 10 and accommodates hollow rod 11 with float 8 secured at its bottom end. Rod 11 has outer ring groove and radial channels 13 aligned with radial channels 10 at bottom position of float 8. Total areas of radial channel holes in rod 11 and cylindrical adapter radial channels 10 may not be less than area of hollow rid axial channel hole.

EFFECT: reduced pressure pulsation, higher reliability and efficiency.
