Process and installation for effluent treatment in oilfields

摘要

In a recontacting tower 2 are treated a gas 3 charged with heavy components or condensates and a liquid 1 virtually free of gas, coming respectively from different reservoirs or oilfields or from the same field but after they have been treated, to collect separately the gas 4 and the oil 5 enriched with heavy components or condensates, and the oil thus obtained is stabilised. The invention is notably applicable for the production of stabilised crude oil at reduced cost. IMAGE
