Oil washing column

摘要

Column wash oil with a coating (10) extending along a longitudinal axis (L) surrounding an interior space (I) of the column (1), the interior (I) divided into a section gasoline (20) and in a disposed below along the longitudinal axis (L) and separate section gasoline (20) especially by means of a bottom chimney (13) oil section (21), arranged in the section gasoline (20) several first funds transfer mass (16, 16a) and arranged in the oil section (21) several seconds funds mass transfer (100), configured column wash oil (1) driving a gas stream decomposition (S) through the second transfer funds mass (100) of the oil section (21) and then through the first funds transfer mass (16, 16a) of the gas section (20), configuring the oil washing column (1) pair applied to the second transfer funds (100) in the oil section (21) a second liquid washing agent (W ') containing hydrocarbons, to separate the gas stream decomposition (S) a fraction of oil (F ') and configured column wash oil (1) for applying to the first funds transfer mass (16, 16a) in the section of gas (20) a first liquid washing agent (W) containing hydrocarbons, to separate the gas stream decomposition (S) a gasoline fraction (F), characterized in that the second funds mass transfer (100) each have a number of output elements (101) run parallel and apart, especially in the form of angle sections, wherein the output elements (101) respectively a first and a second exit surface (102a, 103a), developing the two exit surfaces (102a, 103a) to long e longitudinal je (L) to the section of gas (20) towards each other and coinciding to form a ridge (104) extending transversely to the longitudinal axis (L), so that the washing agent (W ') provided to edges (104) of the output elements (101) out on both sides of the respective edge (104) for the exit surfaces (102a, 103a) of the respective output member (101) and being in the oil section (21 ) the number of seconds funds mass transfer (100) greater than the number of first funds transfer mass (16) in the section of gas (20) and wherein the section of gas (20) along the longitudinal axis (L) a length (a) less than the oil section (21) and configuring the first mass transfer funds (16) as perforated funds, bubbles and / or funds valves.
