Intensification of the process of magnesium extraction from stratal waters of hydrocarbon raw mineral deposits

Passing and formation water of hydrocarbon raw fields has conditioned concentration of magnesium in its composition. The optimal conditions of magnesium extraction by lime method from formation water of Vuktylsky gas-condensate field have been worked out in the laboratory. The usage of acryl flocculant at the stage of deposition allows to destroy colloid deposit of magnesium hydroxide, the deposit particles grow 12 times and more, specific resistance during filtration goes down very much, at the same time the effectiveness of extraction is practically 100 %. On the basis of the tested researches the technological scheme of magnesium isolation from formation water in a kind of magnesium oxide has been developed.
