Definitions
- the invention relates to a technology for the production of inorganic compounds, namely, to a process for the production of ammonium bromide used in pharmacology as a fire retardant, and is also a convenient and cheap to transport raw material for the production of liquid bromine.
- the invention relates to the chemical technology of mineral salts and can be used in the chemical industry.
- a known method of obtaining ammonium bromide [2] by the interaction of a concentrated solution of ammonia with bromine To implement this method, the reactor is first cooled, and bromine is added in small portions. The ammonia released from the solution and the resulting ammonium bromide smoke are captured with water or a weak solution of ammonium bromide. The resulting solution is evaporated and then cooled, and the separated bromide crystals are stripped off, dried and packaged.
- Document [4] describes a method for producing bromine and its salts, related to the technique of absorbing halogens from gas mixtures with liquid absorbers. This invention is aimed at reducing the loss of the reducing agent and the alkaline agent, while there is no description of the process for obtaining the bromine mixture and the raw materials used.
- bromine salts [5] The closest is the method of obtaining bromine salts [5], in which the absorption of bromine is carried out with an excess amount of urea in an alkaline solution in an amount of 101-101.5% of the theoretical one, followed by heating the solution by 60-65 PS with the calculated amount of bromine water.
- This method is energy intensive and does not allow to obtain a high quality finished product due to the formation of carbonates during the recovery of bromine.
- the aim of the invention is to obtain high-quality crystalline ammonium bromide and its aqueous solution.
- the technical result consists in eliminating the stage of purification of the bromine-air mixture from chlorine, and maintaining high purity of the final products and a high degree of bromine recovery.
- the technical result is achieved through a two-stage process of oxidation of bromide ions to elemental bromine with gaseous chlorine, which allows minimizing the content of chlorine impurities in the bromine-air mixture without its additional purification.
- the brine stream purified from dissolved iron, manganese and insoluble impurities, is subjected to preheating to 30-35 °C, neutralization of alkalinity and acidification to pH values - 2.5, using mineral acids to prevent the hydrolysis of free bromine, then bromide ions are oxidized with gaseous chlorine to elemental bromine in two stages: at the first stage, bromide ions are oxidized to elemental bromine at 73-74% of the initial content in the flow chlorinator, operating in a countercurrent mode, wherein the air desorption of elemental bromine is carried out in a countercurrent mode in a desorber, and the absorption of elemental bromine from a bromine-air mixture is carried out in a column-type mass-exchange apparatus, a multidirectional screw nozzle operating in a countercurrent mode, and a chilled
- the subsequent operations of air desorption of bromine, absorption of bromine-air mixture, recovery of absorbed elemental bromine, purification of the resulting ammonium bromide solution are similar to the first stage of oxidation.
- the purified ammonium bromide solution mixed with the mother liquor, from the stage of obtaining crystalline ammonium bromide is evaporated to the required density to obtain an ammonium bromide solution as a commercial product.
- the chlorinator is a vertical apparatus.
- the desorber is a column-type mass transfer apparatus.
- the reactor is a horizontal container divided by partitions into sections: in the first section, bromine is reduced to bromide ion with ammonia water with a concentration of 25% ammonia, in the second section of the reactor, the absorbent is degassed, the released nitrogen is discharged into the atmosphere List of drawings
- the figure 1 schematically shows the sequence of actions of the method for the production of ammonium bromide from bromine polycomponent hydro-mineral raw materials.
- the absorbent saturated with bromine is periodically pumped into the reactor, where the process of reduction of bromine to ammonium bromide (I stage) takes place, dosing 25% ammonia solution.
- the resulting ammonium bromide solution is used for the production of crystalline ammonium bromide.
- the air after bromine extraction, containing some residual bromine, is used for desorption in the second stage.
- Waste water from stage I of desorption enters stage II of oxidation with gaseous chlorine, where 88-90% of bromide ions are oxidized from their residual content to elemental bromine. Further, water from the second stage of oxidation enters the second stage of air desorption of elemental bromine.
- the bromine-air mixture similarly to stage I, is supplied for absorption with the same absorbent (ammonium bromide solution).
- the absorbent saturated with bromine is periodically pumped into the reactor, where bromine is reduced to ammonium bromide (stage II) by dosing 25% ammonia solution.
- the resulting ammonium bromide solution is sent to the production of a commercial form of ammonium bromide solution. Waste water enters the neutralization for its preparation for further disposal.
- Br' 0.64 kg/m 3
- Br' 0.64 kg/m 3
- the absorption of sodium bromide solution and the reduction of elemental bromine with ammonia water were carried out similarly to the first stage.
- Brine volume 2.0 m 3 .
- the overall recovery of bromine from the brine was 96.85%.
