The implementations described herein generally relate to methods and chemical compositions for scavenging sulfur-containing compounds, and more particularly to methods and compositions for scavenging, for example, H 2 S and mercaptans from gaseous sulfur- containing streams. In one implementation, a method for scavenging a sulfur-containing compound from a gaseous sulfur-containing stream is provided. The method comprises contacting the gaseous sulfur-containing stream with an effective amount of a multi- component scavenging system for scavenging the sulfur-containing compound. The multi- component scavenging system comprises at least one scavenger for scavenging the sulfur- containing compound and at least one hygroscopic agent. The gaseous sulfur-containing stream has an amount of water less than or equal to 100% relative humidity and the gaseous sulfur-containing stream comprises the sulfur-containing compound. |
