PROCESS FOR REMOVING CONTAMINANTS FROM GAS USING POLYETHYLENE GLYCOLS |
摘要 |
The present invention provides a process for removing gas contaminants such as hydrogen sulfide and carbon dioxide from a product gas such as natural gas or synthesis gas. According to the invention the product gas is contacted with a solvent which includes dialkyl ethers of polyethylene glycols and water, and a high pressu re recycle loop is utilized to desorb a portion the gas contaminants and co-absorbed product gas from the solvent. The solvent is provided with an amount of water sufficient to increase recovery of co-absorbed product gas while at the same time providing a reduc ed circulation rate requirement for the solvent and reduced re-compression and cooling requirements for the recycle gas.
