Purifying method for hydrogen bromide

Abstract

The invention discloses a purifying method for hydrogen bromide. The method comprises the following steps: performing partial vaporization on the hydrogen bromide; allowing the vaporized hydrogen bromide to enter a Nafion dryer to deeply remove water in the hydrogen bromide; allowing hydrogen bromide gas without the water to enter a light-component removing rectification tower; allowing hydrogen bromide without light components to enter a heavy-component removing rectification tower to remove heavy components in the hydrogen bromide; and discharging hydrogen bromide without the heavy components from the top of the heavy-component removing rectification tower, and allowing the discharged hydrogen bromide to enter a hydrogen bromide storage unit to obtain an electronic-grade hydrogen bromideproduct. According to the method provided by the invention, a novel desiccant is used, and when the water in the hydrogen bromide is simply and efficiently removed, processing equipment of 316L instead of precious materials such as nickel-based alloy is used, so that the equipment investment is greatly reduced.

AI Technical Summary

Benefits of technology

This patented technology describes an improved way to remove impurities from hydrogen peroxide (H2O2) by utilizing different types of chemical agents like calcium oxalate). By doing this, these methods can be more efficient than previous techniques that required expensive specialized facilities. Additionally, they are less prone to damage their products during manufacturing due to lower temperatures involved. Overall, this innovation provides better efficiency and cost savings over existing processes.

Problems solved by technology

This technical problem addressed in this patented text relates to improving the efficiency and precision of producing ultra clean electronics called 99m Tc-99.9m trisbonylnaphthylene sulfone hydride (TFT). However, current methods have limitations including difficulty achieving controlled humidity levels during purifications, potential explosion risks associated with handling liquid nitrogen oxides, and lack of effective removal of mold deposits from hydrocarbysistants like ammoniacal carboxydebuthenium diphosphonate (ADPA2).
