Abstract
The paper considers the possibility of using highly dispersed modified aluminosilicates in the process of extracting hydrogen sulfide from wastewater. The problem of the presence of hydrogen sulfide in natural waters is due to the impossibility of using such waters in human household activities. Water with a high content of hydrogen sulphide has low organoleptic properties, is not suitable for consumption and is highly corrosive. Produced water generated in the process of oil production must also be treated. In the presence of hydrogen sulphide in the produced water, further water injection into the reservoir is highly discouraged, as this can lead to "plugging" of oil-bearing channels. In this regard, the work proposes a method for extracting hydrogen sulfide from natural and waste waters. The work synthesized a new adsorption-coagulation material based on modified aluminosilicates (bentonite clays) using salts of multivalent metals. The possibility of creating a reagent with a different ratio of aluminosilicate matrix: modifier is considered. It was found that the efficiency of the reagent increases with an increase in the pH of the medium. The activity of the reagent in relation to hydrogen sulfide, clarification and removal of oil products was studied. The capacity of the reagents obtained as a result of the modification can reach 32 mg/g in terms of hydrogen sulfide. In the reagent, it is possible to vary the ratio of aluminosilicates and modifiers, which can facilitate the use of the most effective reagent, depending on the conditions. The reagent is capable of extracting not only hydrogen sulfide, but also oil products from the processed aqueous solutions. The reagent binds hydrogen sulfide into insoluble forms, after which the precipitate can be separated from the solution and disposed of.
