used to reduce the velocity and maximize the tangential coherency of the incoming stream as illustrated in fig7 inlets 1 and 2 provide a tangential entry into the separation vessel 3 while inlets 12 and 13 provide a perpendicular entry those of ordinary skill in the art will recognize that locations of inlets 1 2 12 and 13 are illustrative in nature and that the inlets can be positioned anywhere along the outer perimeter of the separation vessel those of ordinary skill in the art will also recognize that the number of inlets used can be widely varied as dictated by the geometry of the separation vessel and by the benefits from a cost standpoint the ratio of non vapor to vapor in the input stream preferably is such that the non vapor is not so dispersed in the vapor that an accelerating force needs to be applied to the stream to form an agglomeration of the non vapor in another preferred embodiment the velocity of the stream is reduced to a rate that does not cause the stream to break up when it contacts the wall of the separation vessel 3 it is preferred that upon introduction into the separation vessel the velocity of the stream is reduced to a rate that is less than the rate at which the breakup of the particles of non vapor in the stream leads to entrainment of such non vapor vapor separates from the stream and exits the separation vessel 3 through vapor outlet 6 at non uniform vapor velocities that are dictated by the design of the separation vessel vapor can be separated from the stream by a reduction in pressure upon entry into the separation vessel or by other methods.
