Abstract
Official abstract text for this publication.
The present invention is directed to the removal of mercury from a gas phase by injecting a scavenger solution into the gas phase.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for removing mercury from a natural gas stream by increasing the mass transfer between gas phase mercury present within the natural gas stream and a scavenger during mercury removal, wherein increasing the mass transfer between the gas phase mercury and the scavenger during mercury removal comprises injecting the scavenger as a fine liquid into the natural gas stream upstream of a glycol dehydration contactor. 2. The method of claim 1 wherein the fine liquid is selected from the group consisting of droplets and particles. 3. The method of claim 2 wherein the injection of the scavenger occurs at a well head to increase the contact time for mercury removal in the gas phase. 4. The method of claim 1 wherein the scavenger comprises sodium polysulfide. 5. The method of claim 1 , wherein the scavenger comprises a mercury scavenger in a glycol solution.
