Method and apparatus for regulating the NH/sub 3/ content in scrubbing liquid used in a gas scrubbing process
Patent
·
OSTI ID:6364316
A process for regulating the NH/sub 3/ content in an organic liquid that acts as a physical scrubbing agent and is used in a procedure for absorbing sour gases from gaseous mixtures. To ensure undisturbed and reliable carrying out of the scrubbing process, an ammonia-precipitating precipitant is added to the scrubbing agent and the precipitate is then separated from the scrubbing agent. Preferred precipitants include sulphuric acid and phosphuric acid. The ammonia salts are effective fertilizers.
