[57] Abstract: The invention relates to a process for preparing hydrocarbons from a gaseous hydrocarbon-containing feed in a plant for preparing hydrocarbons from a gaseous hydrocarbon-containing feed. A hydrocarbon fraction separated out by means of a redistillation column is used for avoiding fouling. As feed material to the redistillation column (1), it is possible to use either condensates or parts of the fractions from the water scrub (2), the crude gas compression (3) or the separation sequence of the hydrocarbon fraction having at least three carbon atoms (4). The hydrocarbon fractions (5) separated out in the redistillation column can then be, in each case together with optionally introduced scrubbing oil (6), recirculated to the water scrub (2) or to the crude gas compression (3).
