High quality filter desander / dual pot sand filter unit for liquid sand separation
Dual-pot sand filter is used to remove sand and other solid particles from oil and gas well effluent to prevent erosion of downstream equipment. Typical applications for the unit include completion clean up and maximum sand-free rate tests. Dual pot sand filter is typically located after the wellhead, flowhead or upstream of the choke manifold.
Dual pot sand filter consists of two filter pots, one manifold and one sand jetting system. 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 by sand jetting system.
