A method for obtaining oil from drilling mud and / or oil-containing drilling sludge fractions

摘要

It is a process for the production of oil (39) of drilling mud (11) and / or oil-containing drilling sludge fractions (11) is proposed. For this purpose, first of all dollars a of the drilling mud (11) and / or the oil-containing drilling sludge fraction homogenized (18) and dispersed in water. Dollars a in the following, the or of the homogenized and dispersed drilling mud (11) and / or drilling sludge fraction (11) is added to the coal dust (19). Dollars a in the following, the resultant suspension is mixed and the mixture or the resulting mass flow (20), in a light fraction (overflow 42), a heavy (28) and an oil-containing coal dust fraction (35) split, finally, from the coal dust - / oil fraction (35) oil (39) by desorption and / or extraction in a desorption equipment (38) or an extraction device is separated off.
