Abstract
There are a device and a method for coalescence separation for a fluid having at least two phases at least partially immiscible with each other and having different specific density or gravity. The separation device has a plurality of sheets or trays that are spaced apart from one another to form passage channels that slow down and divert the flow favouring the coalescence separation.
Claims12
A coalescence separation device for a fluid comprising at least two phases at least partially immiscible with each other and having different specific density or gravity, the device comprising:
- a hollow cylindrical body having a longitudinally axis (A), vertical in use, and provided, at one end, with an opening defining a fluid inlet from above;
- a plurality of axial-symmetrical geometry coalescing sheets with an axis coinciding with the longitudinally axis (A) of the hollow cylindrical body, each of the coalescing sheets comprising a circular central plane portion provided with a through opening and a frusto-conical peripheral portion arranged so that the distance from the opening of the hollow cylindrical body of a plane containing a major base of the frusto-conical peripheral portion is smaller than the distance from the opening of the hollow cylindrical body of a plane containing a minor base of the frusto-conical peripheral portion, the distances being measured along the axis (A) of the hollow cylindrical body, the minor base coinciding with the periphery of the central portion;
- the coalescing sheets being arranged parallel to one another and spaced apart from one another to form passage channels for the fluid, the central plane portion of each coalescing sheet being at least partially protruding with respect to an internal surface of the hollow cylindrical body so as to intercept a portion of fluid flowing inside the hollow cylindrical body and divert it radially inside the passage channels towards the frusto-conical peripheral portions.
A coalescence separation device for a fluid having at least two phases at least partially immiscible with each other and having different specific density or gravity, the device comprising a plurality of axial-symmetrical trays concentrically arranged and generated by plane curves having a substantially elongated “J” shape and spaced apart from one another so as to form passage channels between the strays, the passage channels forming concentric inlet mouths having a circular crown section and intercepting an incoming flow of fluid at an inlet of the separation device, having a direction parallel to the symmetry axis of the axial-symmetrical trays, and conveys the incoming flow of fluid towards exits with prevalently radial direction component of a flow of fluid.
