The invention relates to a method for treating wastewater containing hydrocarbons, in particular hydrocarbons from the group of compounds referred to as BTEX, comprising benzene, toluene, ethylbenzene and xylene aromatic compounds, said wastewater being in particular from the production or conditioning of natural gas, wherein, according to the method, the wastewater is subjected to stripping by the natural gas such that the hydrocarbon pollution is not only removed from the water by means of being transferred to the gas, but also eliminated during the subsequent combustion of the gas. The wastewater to be treated has a soluble BTEX content that is no higher than 1,200 ppm, preferably no higher than 900 ppm, and the weight ratio of the stripping gas to the treated water is less than 10%, the water being discharged from the stripper having a soluble BTEX content that is no higher than 30 ppm.
A process for treating wastewater containing hydrocarbons, in particular hydrocarbons from the group of compounds referred to as BTEX, comprising benzene, toluene, ethylbenzene and xylene aromatic compounds, this wastewater originating in particular from the production or conditioning of natural gas, the process comprising subjecting the wastewater to stripping by natural gas in a stripper such that the hydrocarbon pollution is removed from the water by transfer into the gas and is also eliminated during subsequent combustion of the gas, wherein:
A facility for treating wastewater containing hydrocarbons, in particular hydrocarbons from the group of compounds referred to as BTEX, this wastewater originating in particular from the production or conditioning of natural gas, the facility comprising a combustible-gas, in particular natural-gas, a stripper (4A), in which the wastewater is subjected to stripping, such that the hydrocarbon pollution is removed from the water by transfer into the gas and is also eliminated during the subsequent combustion of the gas,
