1. An apparatus for coalescing particles of a first fluid entrained in a flow of a second fluid, wherein the first fluid has a higher density than the second fluid, the apparatus comprising:
a housing; an enclosure formed in the housing, the enclosure defining a longitudinal axis and having at least one curved wall arranged to direct fluid flow along at least one said curved wall in a curved path; a first inlet duct to the enclosure provided at a first location along the longitudinal axis for enabling introduction of a fluid flow substantially along a tangent to at least one said curved wall, the first inlet duct defining a first channel along which fluid flow is directed, the first channel having a decreasing cross sectional area along the direction of fluid flow; an outlet from the enclosure provided at a second location along the longitudinal axis, remote from the first location, for enabling exit of the fluid flow substantially along a tangent to at least one said curved wall, wherein the enclosure is arranged to direct fluid flow along the at least one curved wall between an end of the first inlet duct disposed in the enclosure and the outlet to cause particles of the first fluid to coalesce and exit the outlet. |
