H2S/ VOC / C2H4 Removal

All industrial Chemical operations at petrochemical plants, refineries, fertilizers and related Processes generate a lot of unwanted gases and by-product gas streams which are harmful for the environment.

Proper elimination of these contaminants is a must to ensure clean environment practices and no harm to the surrounding air. Adox media have been specially formulated to eliminate such contaminants in the process streams for wide applications.

Adox uses a combination of adsorption, absorption and oxidation processes to eliminate a broad range of effluents. With speciality grade alumina-zeolites blended with the highest performance additives, it provides a unique surface contact for the chemical reaction to take place between the media and effluent molecules.

Target Effluents
  • Acid Gases
  • Nitrogen and Sulphur Compounds
  • Light Molecular Weight Gases

Adox is very effective in removal light weight organics and related chain compounds, formaldehyde and oxides of nitrogen and sulphur. It is not commended for heavy VOC’s or aromatics. For applications containing both acid gases and VOCs, please contact us for a different product.

Uses
  • Refinery and petrochemical effluent gas treatments
  • Fertilizer plants
  • Water and sewage treatment
  • HVAC systems
  • Chemical process industry
Specifications
  • Shape: Beads/Granules

Frequently Asked Questions (FAQs)

Q1: What are gas absorbents, and how do they work?

A: Gas absorbents are specialized materials designed to remove gaseous impurities and contaminants. They function by chemically or physically capturing gases, ensuring that the treated gas stream is cleaner and safer for various industrial and commercial applications.

Q2: What is a soda lime absorbent, and how does it remove CO₂?

A: A soda lime absorbent—such as our CoxOut product—is an active mixture of hydroxides that chemically reacts with carbon dioxide. This reaction effectively removes CO₂ and other acidic contaminants from gas streams, making it an ideal CO₂ absorbent for a range of applications including medical and industrial settings.

Q3: What is the CO₂ absorption capacity of your soda lime absorbent?

A: Our CoxOut soda lime absorbent has an impressive CO₂ absorption capacity of over 140 liters per kilogram, ensuring efficient and effective removal of carbon dioxide from various gas streams.

Q4: In what forms and sizes are the soda lime absorbents available?

A: CoxOut is available in both granular and pellet forms. The absorbent is manufactured in two size ranges—1-3 mm and 2-5 mm—to suit different equipment and process requirements.

Q5: What is the difference between CoxOut and Adox products?

A: CoxOut is a soda lime-based CO₂ absorbent specifically formulated for removing carbon dioxide and related acidic gases. In contrast, Adox is designed to remove a broader range of contaminants—including H₂S, VOCs, and C₂H₄—by leveraging a combination of adsorption, absorption, and oxidation processes.
