METHOD AND FACILITY FOR THE TREATMENT OF WATER FROM OIL AND GAS INDUSTRIES, ESPECIALLY WATER PRODUCED FROM OIL AND/OR GAS FIELDS

摘要

The invention relates to a method for treating water from oil and gas industries, especially water produced from oil and/or gas fields, for the reuse thereof, comprising a step (6, 7) of filtration of said water on reverse osmosis membranes, and a step (4, 5) of adsorption of the organic material contained in said water, said step of adsorption being provided upstream of said filtration step and being implemented on at least one adsorbent resin selected from the group consisting of the non-ionised cross-linked polymer resins and the microporous carbonaceous resins. The invention also relates to a corresponding facility. Said method further comprises a step of the in situ regeneration of the adsorbent resin, carried out by a regeneration means selected from the group consisting of water vapour, a solvent, a base and/or an acid.
