Development of a Non-Reagent Method for Extraction of Iodine from Reservoir Waters of Oil and Gas Deposits

Abstract

Currently, two methods of extracting iodine are mainly used: air-desorption and ionexchange. Common to these methods is the use of chemical reagents such as sulfuric acid and chlorine in the stages of acidification and oxidation, which are the main sources of costs in the production of iodine and environmental pollution. Therefore, the development of technology for the processing of reservoir waters in oil production with the goal of isolating such elements as iodine for further use is an urgent task of rational nature management. A new method for extraction of iodine from the geothermal reservoir water and oil and gas fields in Western Siberia, which eliminates the use of chemicals in the technological scheme, which reduces the environmental burden on the environment. This technology was tested in a pilot plant and can be used in the preparation of iodine-bromine water Cherkashinskoye field Tyumen Oblast of the Russian Federation.
