Title: GRAVITY DESANDING APPARATUS WITH FILTER POLISHER
Abstract:
Apparatus and method disclosed herein related to first stage gravity separation of liquid and sand from a gaseous fluid stream in an upper portion of a desanding vessel, sand separating from gas along an annular path about a shell, the sand-free gas directed back down into the shell to a fluid outlet for removal as a product stream. A second stage gravity separation of sand from accumulated liquid occurs in a lower section of the vessel. An optional final or polishing stage of the liquid is conduct using a filter. A stacked-plate filter can extend an intake opening of the fluid outlet into the accumulated liquid. Further, the filter plates can be configured with parallel filtering of gas/liquid separation for gas intake above, and with liquid/sand separation below including pressure management of the filter operation.
