An apparatus comprising, (a) a vessel capable of containing a liquid and a gas, said vessel being partly defined by a sidewall which defines a generally cylindrical inside surface, said vessel having a longitudinal axis about which the sidewall is generally symmetrically positioned; (b) a pipe mounted in said vessel, said pipe having a sidewall; (c) a partition mounted in said pipe dividing the inside of the pipe into a first chamber and a second chamber; (d) a first tubular member having a first end attached to the sidewall of the pipe and a second end having a closure thereon; (e) a second tubular member having a first end attached to the partition and a second end spaced apart from the end closure of the first tubular member, the second tubular member extending inside of the first tubular member; wherein a flow path is formed from the first chamber, through the second tubular member, through an annulus between the second tubular member and the first tubular member, and into the second chamber; (f) a fluid inlet means extending through the sidewall of the vessel and connected to the first chamber wherein the fluid inlet means comprises a feed pipe extending through the sidewall of the vessel and a curved supply pipe extending generally circumferentially around the inside of the vessel at a position spaced apart from the sidewall of the vessel and connected to the first chamber by a riser feed; (g) a fluid outlet means extending through the sidewall of the first vessel and connected to the second chamber wherein the fluid outlet means comprises a first exhaust pipe extending through the sidewall of the vessel connected to a curved collection pipe extending generally circumferentially around the inside of the vessel at a position spaced apart from the sidewall of the vessel and a riser exhaust pipe connecting the second chamber to the curved collection pipe. A process comprising (a) introducing a heat exchange fluid into a vessel through an inlet means extending through the vessel wall; (b) distributing the heat exchange fluid from the inlet means into a plurality of first heat exchange tubes each having a first end and a second end and connected by the first end to the inlet means; (c) flowing the first heat exchange fluid from the first end to the second end of the plurality of first heat exchange tubes; (d) emitting the first heat exchange fluid from the second end of the first plurality of heat exchange tubes and into the first end of a second plurality of heat exchange tubes each concentrically positioned around a heat exchange tube of the first plurality and flowing the heat exchange fluid from the first end of the second plurality of heat exchange tubes, along a plurality of annuli defined between the first heat exchange tubes and the second heat exchange tubes, to a second end of the second heat exchange tubes; (e) discharging the heat exchange fluid from the second end of the second heat exchange tubes and collecting the discharged heat exchange fluid in an exhaust means which extends through the vessel wall; and (f) withdrawing the heat exchange fluid from the vessel through the exhaust means.
