Abstract

It is disclosed an apparatus for separating a least one solid from a solids/fluid mixture, said apparatus comprising a separation chamber and a cushion chamber. The separation chamber comprises a top end, a bottom end, at least one wall, and an inlet port for introducing the solids/fluid mixture, said inlet port having an inlet port vector. The cushion chamber comprises at least one boundary wall, and it is adapted to maintain a cushion of the solids/fluid mixture at an intersection of the inlet port vector and the cushion chamber when the separation chamber and the cushion chamber are connected by a communication port at the intersection of the inlet port vector and the at least one wall. The communication port has an area at least a size of an impact area of the solids/fluid mixture on the at least one wall. The communication port may be formed by the erosion of the at least one wall of the separation chamber caused by the solids/fluid mixture at the impact area.It is also disclosed a process for separating a solids/fluid mixture, wherein the solids/fluid mixture is introduced through the inlet port of the separation chamber and contacted with a cushion of a previously introduced…
