A de-sanding tank with a conical bottom. The de-sanding tank includes an enclosed tank having a vertical wall that extends down to a flat bottom. A conical bottom is disposed within an interior of the tank. The conical bottom is secured to the vertical wall forming an enclosing space bounded by a wall of the conical bottom and the vertical wall and flat bottom of the tank. A solids outlet is disposed at a lower tip of the conical bottom configured for removal of solids. The conical bottom is supported by a foam structure located within the enclosing space.

An apparatus and a process enable separating components of a multiphase hydrocarbon stream. The apparatus may include an outer vessel having a top end with a top outlet and a bottom end with a bottom outlet, with a longitudinal axis extending between the top end and the bottom end. An outer vessel body disposed between the top end and the bottom end has an outer vessel internal volume in fluid communication with the top outlet and the bottom outlet. The outer vessel body may include a first section with a tangential inlet arranged to introduce the multiphase hydrocarbon stream tangentially into the outer vessel internal volume to create a vortex flow, and a second section arranged closer to the bottom end than the first section. The outer vessel internal volume has a smaller cross-sectional circumference in the second section than in the first section. An inner vessel disposed within the outer vessel body includes an inner vessel body having an inner vessel internal volume, and an inner bottom inlet oriented toward the bottom end of the outer vessel and in fluid communication with the inner vessel internal volume and with the outer vessel internal volume. A traversing conduit in fluid communication with the inner vessel internal volume may traverse the outer vessel body.

A fluid separator includes a body, an inlet, a first outlet and/or a second outlet. The first outlet may include a vortex finder that may have a convergent-divergent configuration. The second outlet may include or may be connected to a pressure relief valve. At least a portion of the pressure relief valve may be disposed in the vortex finder. The pressure relief valve may be disposed entirely outside of the vortex finder. The vortex finder may include a divergent section and a convergent section. In embodiments, the divergent section may be at least twice as long as the convergent section, a taper angle of the convergent section may be at least twice as large as a taper angle of the divergent section, and/or an axial length of a portion of the vortex finder extending into the body may be at least 1.5 times a diameter of the inlet.

A separation device for separating a cyclone chamber from a collection chamber of a cyclonic separator has a guide member that includes a leading end, a trailing end, and a guide surface. The guide surface guides debris entrained in an airflow in the cyclone chamber in a helical path about an axis of the separation device and into the collection chamber. The guide surface extends about the axis of the separation device through an angle of less than 360 degrees for allowing debris in the cyclone chamber to also pass into the collection chamber from the cyclone chamber in an axial direction. The leading end of the guide member is at an angle between 30 and 60 towards the cyclone chamber with respect to the axis of the separation device to promote a helical flow of air and debris flowing over the guide surface.
