摘要： Basic nitrogen compounds are removed from organic streams which are substantially free of water by contacting the stream with gaseous sulfur dioxide thereby precipitating a complex containing the basic nitrogen compounds and sulfur dioxide, and thereafter separating the precipitating complex from the contacted stream. The basic nitrogen compounds and the sulfur dioxide can then be regenerated from the complex.

摘要： 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.

摘要翻译： 从含有至少化学计量量的水的有机物流中除去碱性氮化合物，但不会产生将导致两相液体体系的水。 将该物流与气态二氧化硫接触，由此使含有碱性氮化合物，二氧化硫和水的盐沉淀，然后将沉淀的盐与接触的物流分离。 然后碱性氮化合物和二氧化硫可以从盐中再生。
