| titleOfInvention | Method and system for purifying primary liquid ammonia into high-purity liquid ammonia |
| abstract | A method for purifying primary liquid ammonia into high-purity liquid ammonia uses the difference in the condensation temperature of the impurities in the primary liquid ammonia to remove the impurities in stages. Firstly, the primary liquid ammonia is heated with warm water, and the ammonia is vaporized into vaporized ammonia gas, and the impurities in the primary liquid ammonia that cannot be vaporized are left in the storage tank to obtain preliminary purification; then the difference in gas condensation temperature is used to remove the impurities in the ammonia gas Use liquefaction and non-condensing modes to separate and discharge, so that ammonia can be effectively purified. The first step is to use low-temperature water to distill the ammonia so that the oil and metal ions in the primary liquid ammonia cannot be evaporated and left in the storage tank; further use the cooling wet film to absorb impurities with a condensation temperature higher than ammonia, such as water, propane, and ketones Wait, let it form liquefaction and condense to form waste ammonia water and stay in the purifier, let gas phase ammonia and liquid phase impurities separate, and ammonia gas will be further purified; and then further condense and liquefy ammonia gas to form liquid ammonia, which is more condensed in ammonia gas than ammonia Impurities with low temperature, such as nitrogen, carbon diamide, and methane, cannot be condensed, allowing liquid ammonia to be separated from gas phase impurities and then removed, allowing liquid ammonia to be effectively purified and converted into high-purity liquid ammonia. |
