About MEA Triazine 78% H2S Scavenger

MEA Triazine 78% is a high-concentration hydrogen sulphide scavenger formulated for oil and gas applications. It reacts irreversibly with H₂S to form non-hazardous dithiazine by-products, ensuring efficient sweetening of crude oil and natural gas streams. Manufactured by Vasudev Chemo Pharma at our ISO 9001:2015 certified facility in Gujarat, India, this product is supplied at a guaranteed minimum active content of 78%, making it one of the most concentrated MEA Triazine solutions available in the market. It is compatible with both contact tower and direct-injection scavenging systems, and is suitable for sour gas treatment, amine unit support, and pipeline sweetening operations.

Frequently Asked Questions

What is MEA Triazine 78% and how does it remove H2S?+
MEA Triazine 78% (1,3,5-tris(2-hydroxyethyl)-s-triazine, CAS 4719-04-4) is a liquid hydrogen sulphide scavenger that reacts irreversibly with H₂S to form water-soluble, non-toxic dithiazine by-products. At 78% active content, it is one of the most concentrated MEA Triazine solutions available, providing superior scavenging efficiency per litre compared to lower-concentration alternatives. It is widely used in natural gas sweetening, crude oil stabilisation, and biogas desulphurisation.
What is the difference between MEA Triazine and MMA Triazine?+
MEA Triazine (monoethylamine-based) and MMA Triazine (monomethylamine-based) are both triazine H₂S scavengers, but they differ in chemistry and application profile. MEA Triazine 78% offers higher active content and faster reaction kinetics, making it ideal for high-H₂S-concentration streams. MMA Triazine 40% is a BTEX-free alternative preferred for applications where BTEX emissions must be minimised, such as in gas processing plants subject to strict VOC regulations.
How much MEA Triazine 78% is needed to treat 1 ppm of H2S?+
The stoichiometric ratio is approximately 3.1 kg of MEA Triazine 78% per kg of H₂S removed. In field practice, actual consumption is typically 4–6 kg per kg of H₂S due to inefficiencies in contact, competing reactions, and temperature effects. Exact dosing depends on H₂S concentration, gas flow rate, contact time, temperature, and whether a contact tower or direct-injection system is used. Vasudev Chemo Pharma's technical team can assist with dosing calculations for your specific application.
Is MEA Triazine 78% safe to handle?+
MEA Triazine 78% is classified as an irritant (GHS07). It may cause skin and eye irritation (H315, H319) and respiratory irritation (H335). Standard handling precautions include chemical-resistant gloves, safety goggles, and adequate ventilation. It is non-flammable (flash point > 93°C) and fully miscible in water, making spill cleanup straightforward. A Safety Data Sheet (SDS) is provided with every shipment from Vasudev Chemo Pharma.
What is MEA Triazine 78% H2S Scavenger used for?+
MEA Triazine 78% H2S Scavenger (CAS 4719-04-4) is used for H₂S scavenging in natural gas, Crude oil sweetening, Amine unit support. It is manufactured by Vasudev Chemo Pharma at our ISO 9001:2015 certified facility in Gujarat, India, and is suitable for industrial and commercial applications across Oil & Gas, Petrochemicals, Refineries sectors.
What is the CAS number of MEA Triazine 78% H2S Scavenger?+
The CAS (Chemical Abstracts Service) Registry Number of MEA Triazine 78% H2S Scavenger is 4719-04-4. The molecular formula is C₆H₁₅N₃O₃ with a molecular weight of 177.20 g/mol. The HS code for international trade is 29336990.
