ABSTRACT:
A power recovery separator for processing huge volumes of high temperature pressurized dirty gas en route to a high temperature gas expander. The separator has a single housing sub-divided into overhead, inlet and underflow chambers by a pair of flanged and dished heads of erosion and heat resistant material having a higher coefficient of expansion than the housing material. A multiplicity of inertial separators are supported in parallel between the dished heads and secured to only one thereof. At least portions of the head flanges bear radially against the interior of the housing sidewalls and their rim edges are welded to the housing and, in consequence, expansion of the head serves, in part, to augment the bulge and, in part, to place the high strength housing wall in hoop tension without subjecting the welding to rupture stresses. All gas handling ducts are connected only to the housing wall thereby avoiding the need for any internal housing, any internal ducts, distribution screens or any expansion joints.
