Use of Formation Water and Associated Gases and their Simultaneous Utilization for Obtaining Microelement Concentrates Fresh Water and Drinking Water

Abstract

Abstract Purpose: The invention relates to the oil industry, inorganic chemistry, in particular, to the methods of complex processing of formation water, using flare gas of oil and gas field as fuel for producing enriched concentrates of iodine, bromine, magnesium and valuable trace elements, as well as desalinated water (technical and drinking water). The technology includes pre-cleaning of formation water from mechanical impurities and oil using adsorbents, followed by evaporation of water under vacuum, condensing water vapor in the barometric condenser, using of condensed water vapor as the coolant, using of saline water as a coolant of hot water coming out of the barometric condenser to 15–20 °C. The novelty of the design?: The novelty of the design is to get a comprehensive treatment of formation water, using flare gas of oil and gas field as fuel for obtaining enriched concentrates of iodine, bromine, magnesium and valuable trace elements, as well as desalinated water (technical and drinking water)....
