Abstract
An apparatus and method for removing particulates from a multiple-phase fluid stream is disclosed. The apparatus comprises a treatment chamber having a fluid inlet for receiving the multiple-phase fluid stream. The apparatus also comprises a recovery chamber having a gas channel and a liquid channel in fluid communication with the treatment chamber at a gas and a liquid port, respectively. The gas and liquid channels converge at an intake port of a fluid outlet for discharging particulate-removed gas and liquid.
Claims21
A desanding device for removing at least particulates from a multiple-phase fluid stream containing at least gas and entrained particulates, the desanding device comprising:
- a vessel forming a treatment chamber, the treatment chamber having a fluid inlet for receiving the fluid stream;
- a recovery chamber having
- a first upper port in fluid communication with an upper portion of the treatment chamber for receiving gas therefrom,
- a second lower port in fluid communication with a lower portion of treatment chamber, and
- a fluid outlet intermediate the first and second ports for discharging at least particulate-removed gas out of the treatment chamber.
The desanding device of claim 7 wherein the cross-sectional areas of the recovery chamber is much smaller than the cross-sectional area of the treatment chamber.
A method of removing at least particulates from a multiple-phase fluid stream containing at least gas and entrained particulates, the method comprising:
- establishing a treatment chamber;
- establishing a first channel between the treatment chamber and a fluid outlet for directing particulate-removed gas from the treatment chamber to the fluid outlet through the first channel;
- establishing a second channel between the treatment chamber and the fluid outlet;
- injecting said fluid stream into the treatment chamber to allow at least a substantial amount of the entrained particulates fall out of the fluid stream and move into a lower portion of the treatment chamber;
- and
- discharging the particulate-removed gas via the fluid outlet.
