Natural gas desulphurizing apparatus and method
First Claim
Patent Images
1. A method for continuously desulphurizing natural gas and continuously regenerating a reaction solution, comprising the steps of:
- reacting natural gas in a substantially closed tower by contacting said gas with a metallic oxide solution so as to substantially oxidize the sulphurous compounds in said gas;
degassing said reaction solution by transporting said reaction solution through a colloid mill and venting entrained gases released therefrom;
continuously regenerating said reaction solution by treating said reaction solution with an oxidizing agent to reduce the sulphur in said reaction solution to cause it to precipitate for collection and recycling said solution to said tower for additional reactions.

Abstract
A desulphurization apparatus and method for natural gas in which red iron oxide is reacted with the sulphur compounds found in natural gas to remove these compounds from the gas. The treating solution is then recycled to regenerate the red iron oxide solution with elemental sulphur formed as a byproduct for removal.
