Abstract
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, H2S 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.
