which in turn may be mounted on skids 35 and the skids 35 may also support a tank 36 which may be used as a heater for the horizontal gas and liquid separator by referring now to fig2 of the drawings an enlarged vertical section on line 2 2 of fig1 may be seen with the inlet port 13 communicating with the l shaped tubular connection 17 by which the inlet gas is tangentially directed through the opening 20 into the centrifugal separator and specifically the outer cylinder body 18 thereof in fig2 of the drawings a spider 37 will be seen to be positioned with its arms engaged on the outer cylindrical body 18 and the inner cylindrical body 19 and supporting the same in spaced relation in fig3 of the drawings the baffle 25 will be seen to form a transverse closure with respect to the downstream end of the settling section 22 of the horizontal gas and liquid separator with the screen 26 and its structural support extending transversely of the tank 10 between the side walls thereof this structure restricts the gas flow by again referring to fig1 of the drawings it will be seen that the screen 26 and its structural support are also supported by the secondary tall baffle 24 and the third baffle 25 the arrangement is such that a restricted open transverse area in the upper portion of the tank 10 permits the gas stream flowing through the horizontal gas and liquid separator to engage a substantially large area of the primary ceramic mist extractor including the chips 27 the mist extracted by the primary mist extractor is.
