Abstract
An aqueous composition comprises at least one oxidizable sulfur-based compound. A concentrated extract of the aqueous composition includes a gas chromatography/mass spectrometry-detectable amount of contaminating refinery hydrocarbons but the aqueous composition is free of refinery odor when stored for at least 24 hours at room temperature and 60% relative humidity. The aqueous compositions are prepared from a gas stream obtained from a petroleum refinery process, a coke oven, or the like, containing at least about 4 mol %, more specifically about 15 mol %, of hydrogen sulfide (HS) and/or sulfur dioxide (SO) and/or ammonia (NH), and at least about 0.1 mol % of contaminating refinery hydrocarbons. The aqueous compositions are suitable for use in fertilizers, mining and industrial applications.
