Abstract
A sand separation system for continuous sand disposal is disclosed. It includes a sand catching vessel to receive a multi-phase fluid stream (e.g., oil and gas production) containing settleable solids such as sand. A siphoning conduit connected to the vessel's lower end facilitates for continuous sand disposal. Continuous sand disposal is an operational improvement over conventional batch sand disposal systems. The separation system may feature a control valve on the siphon conduit to regulate sand flow and a water inlet to inject water into the sand collecting vessel. This continuous sand disposal design improves operational efficiency by avoiding separator downtime caused by batch removal of accumulated sand.

Siphoning outlet conduit with two downcomer segments and one riser segment at disposal port for cyclonic separator's catching vessel A sand catching vessel system, the sand catching vessel system comprising a sand catching vessel and a siphoning conduit,
- a. The sand catching vessel comprising a vessel enclosure, a sand inlet, and a disposal port;
- the vessel enclosure being disposed within the sand catching vessel, the sand catching vessel having an upper end, a lower end, and a lateral wall, the sand inlet being an opening through the vessel enclosure where a sand stream enters the vessel enclosure, the disposal port being an opening through the vessel enclosure where a disposal stream exits the vessel enclosure, the disposal port being disposed towards the lower end of the vessel enclosure, the disposal stream exiting the vessel enclosure being conveyed into the siphoning conduit,
- b. The siphoning conduit comprising a first downcomer segment, a first riser segment, and a second downcomer segment, the first downcomer segment being joined to the disposal port, the first riser segment being joined to the first downcomer segment downstream of the first downcomer segment, a low point being disposed between first downcomer segment and the first riser segment, the second downcomer segment being joined to the first riser segment downstream of the first riser segment, a high point being disposed between first riser segment and the second downcomer segment, the disposal stream exiting the downstream end of the second downcomer segment.
