Dual-pot sand filter (high pressure sand separator) is used to remove sand and other solid particles from oil and gas well effluent to prevent erosion of downstream equipment. Typical application for the unit include completion cleanups and maximum sand-free rate tests.
Typical applications for the unit include completion cleanups and maximum sand-free rate tests. This filter is typically located after the well Surface Test Tree upstream of the choke manifold.
Dual pot sand filter consists of two filter pots and a manifold. The frame-mounted pots have lifting support for convenient filter replacement. Both of two pots can be on stream at same time. Normally, one vessel is in use, another is being cleaned.
