Device for liquid degassing

A device for liquid degassing by means of swirling or centrifugal force coupled with a pressure gradient, comprising a vertical cavity, wherein the cavity comprises a top end and a bottom end, has a maximum diameter and is furnished with an inlet for a liquid-gas mixture, a gas outlet and a liquid outlet, wherein the gas outlet is realized through an overflow pipe inserted into the cavity through the top end of the cavity, and positioned around 0.1-3 times the maximum diameter of the cavity from the top of the cavity,

• wherein the cavity comprises a column-shaped segment, and a frustum-shaped segment beneath and connected to the column-shaped cavity via its larger base, wherein the diameter of the larger base of the frustum-shaped segment is the same as the diameter of the column-shaped segment,
• wherein the overflow pipe comprises, from the bottom to top, (i) a bell mouth section with a frustum-shaped internal cavity, (ii) a column section connected to the narrow end of the open mouth section, and (iii) an inverted frustum-shaped connection section connected to column section at its narrow end,
• wherein the bell mouth section has a thick wall, configured in such a way that the exterior of the bottom of the overflow pipe forms an inverted frustum and tapers toward the gas-phase outlet opening,
• wherein the overflow pipe is connected to a second overflow pipe through the wide end of the inverted frustum-shaped connection section,
• wherein a barrel body encloses the overflow pipe and at least part of the second over flow pipe, and
• wherein the bottom end of vertical cavity is furnished with an endocone whose bottom cross section area is larger than the cross section area of the gas outlet.
