ABSTRACT:
Basic nitrogen compounds are removed from organic streams containing at least a stoichiometric amount of water but not so much water that would cause a two phase liquid system. The stream is contacted with the gaseous sulfur dioxide, thereby precipitating a salt comprising the basic nitrogen compound, sulfur dioxide, and water and thereafter separating the precipitated salt from the contacted stream. The basic nitrogen compounds and the sulfur dioxide can then be regenerated from the salt.
