A hydrocyclone for separating a combined phase input stream has two nesting truncated, downwardly tapering conical members having an annular space therebetween. A tangential inlet leads to the annular space between the conical members. Alternate embodiments applicable to a hydrocyclone device composed of nesting cylindrical or conical shells forming an annular cyclonic space have passages located on either of the shells to effect an intermediate draw off of a fraction of the flow stream. In addition, a coiled, hollow tube is advantageously situated within the annular space to optimize the flow pattern. Ports may be provided in the hollow tube for removing a gas fraction in counterflow orientation.

[ We claim:] [12.] A separator apparatus for separating a combined phase input stream composed of at least a gas and a liquid, comprising a hydrocyclone coupled to a secondary separator, the hydrocyclone comprising an inner shell residing concentrically within an outer shell, the two shells forming an annular space therebetween of constant width, an inlet leading into the hydrocyclone, an outlet leading out of the hydrocyclone, an uptake port for removing a light fraction separated from the input stream within the hydrocyclone from a collection area located radially inward from the shell and leading upwardly from a point above a liquid operating level of the hydrocyclone into said secondary separator, a return port leading from said secondary separator downward into the hydrocyclone and having an outlet point below said operating level.
