Product Overview

The Hydrogen Sulfide Gas Removal System is a comprehensive gas purification solution designed to remove H₂S from industrial gas streams through chemical absorption, physical adsorption, or hybrid purification technologies.
The system integrates gas pretreatment, absorption, circulation, post-treatment, and automated monitoring into a compact and reliable purification unit suitable for natural gas, refinery gas, biogas, and industrial exhaust gas applications.

Technology

The system utilizes chemical absorption technology in which H₂S reacts with alkaline solutions such as sodium hydroxide (NaOH) or amine solutions to form soluble sulfur compounds.
For specific applications, physical adsorption media such as activated carbon or molecular sieves can also be integrated to enhance purification efficiency and adapt to varying gas compositions.

Process Flow
