Abstract
Apparatus and method is provided for capturing centrifugally-liberated liquid from a gas stream including separator components installed in a cyclonic vessel. A plurality of concentric shells supported on a base form annular cavities arranged about a gas outlet for capturing separated liquids from a spinning gas stream. The shells can be suspended from an insert manufactured with or retrofit to a vessel. Helical vanes aid in maintaining the spinning gas stream. In low moisture conditions, liquid removal through annular cavities can be supplemented with an annular layer of packing adjacent the vessel wall.
Claims18
Apparatus for treating a gas stream containing liquid and being adapted to a vessel having cylindrical side walls, a bottom end, and a tangential gas inlet adjacent a top end, the apparatus comprising:
- a base plate positioned below the tangential gas inlet;
- at least one cylindrical shell arranged on the base plate and adjacent the wall portion for forming at least one annular cavity extending upwardly from the base plate and having an open end for receiving liquid therein;
- an opening in the base plate at each annular cavity for draining liquid from the at least one annular cavity;
- an outlet for the gas stream positioned adjacent the base plate and within the annular shells;
- and
- a plate above the gas outlet for directing the gas stream over the one or more annular cavities before a drier gas stream is removed through the gas outlet,
- wherein the base plate divides the vessel into an upper gas cyclonic separation portion above the base plate and a lower liquid storage portion for receiving liquid from the one or more openings in the base plate.
Apparatus for treating a gas stream containing liquid comprising:
- an insert adapted for installation into a cylindrical vessel having a bottom end and having a tangential gas inlet adjacent a top end for spinning the gas stream, the insert having a bottom end and a top end;
- a base plate at a bottom end of the insert;
- one or more cylindrical annular shells arranged on the base plate, the first of the shells positioned adjacent the vessel for forming at least one annular cavity extending upwardly from the base plate for receiving liquid therein;
- one or more openings in the base plate at each annular cavity for draining liquid from each annular cavity;
- an outlet for the gas stream positioned adjacent the base plate and within the annular shells;
- and
- a plate for directing the spinning gas stream over the annular shells before a drier gas stream is removed through the gas outlet,
- wherein the base plate divides the vessel into an upper gas cyclonic separation portion above the base plate and a lower liquid storage portion for receiving liquid from the one or more openings in the base plate.
