Metered Chemical Injection
Storage tank, metering pump and injection quill form the core of a controlled H₂S scavenger dosing system.

H2S-50
50% MEA TRIAZINE H₂S SCAVENGER
50% MEA TRIAZINE H₂S SCAVENGER
Water-based monoethanolamine-based triazine scavenger for oil & gas H₂S treatment systems. H2S-50 is positioned as a balanced mid-active grade combining higher delivered active content than H2S-50 with practical liquid handling for general treatment programs.
High-active treatment chemistry
BALANCED ACTIVE. GENERAL-PURPOSE FORMAT.
EXPLORAX H2S-50 is a water-based MEA-triazine solution positioned between the lower-active H2S-50 and the more concentrated H2S-50 / H2S-80 grades. It provides a balanced active concentration for customers who want a general-purpose liquid scavenger format with straightforward storage, transfer and metered injection.
Water-based liquid
Clear to pale-yellow liquid with mild amine odour and water solubility.
Balanced concentration
A mid-active option for customers seeking a compromise between concentration and handling flexibility.
Controlled injection
Designed for metered treatment concepts where dosage is established by actual H₂S loading and process conditions.
Qualification required
Final dosage depends on inlet H₂S, flow, pressure, temperature, contact conditions and treatment target.
TREATMENT VISUALS
FROM INJECTION
TO TREATED STREAM.
MEA-Triazine Contact & Reaction
Sour stream contacts triazine chemistry and exits with reduced H₂S concentration.
Production Treatment Point
Scavenger injection can be integrated around separators, gas outlets and downstream process equipment.

TREATMENT LOGIC
CONTACT.
REACT.
VERIFY.
The internal page should communicate H₂S scavenging as a controlled treatment sequence rather than a single generic claim. In practice, the required dose and contact conditions depend on the actual sour stream and operating target.
Typical injection concept
The scavenger is metered into the sour gas or process stream, mixed with the stream, allowed to contact and react, and followed by verification of the treated outlet. The attached process graphic is presented as an application illustration rather than a fixed engineering design.
01
Detect
Establish inlet H₂S concentration and treatment target.
02
Inject
Meter H2S-50 at a controlled injection point suited to the process.
03
Contact
Provide adequate mixing and residence time for the scavenging reaction.
04
Verify
Measure downstream H₂S and optimize dosage against actual performance.
APPLICATION DIRECTIONS
WHERE H2S-50
CAN BE EVALUATED.
Sour Gas Treatment
Continuous or staged scavenger injection into sour gas streams where a liquid MEA-triazine treatment route is appropriate.
Separator / Production Gas
Injection around separator gas outlets or downstream production-treatment equipment to reduce H₂S before further handling.
Crude / Liquid Systems
Can be evaluated in selected hydrocarbon or process liquid applications where H₂S control is required and compatibility is confirmed.
Storage & Transfer
Useful as a treatment concept for tanks, transfer systems and process lines when H₂S control is required during handling.
Pipeline Injection
Metered injection can be considered where mixing and contact time in the line support the intended treatment objective.
Field Qualification
Dosage should be optimized using actual inlet H₂S, flow, temperature, pressure and downstream target values.
PACKAGING & LOGISTICS
FLEXIBLE GRADE.
PRACTICAL SUPPLY.
The 50% grade is positioned as a balanced mid-active supply format. It delivers more active chemistry per package than H2S-50 while retaining greater carrier content than the 60% and 80% grades. Final pack size and shipment configuration should follow the approved commercial specification.
Packaging
IBC / drum / bulk options to be confirmed against the current commercial pack specification.
Active delivery
The 50% concentration provides a middle ground between active delivery and carrier content.
Handling
Dynamic viscosity at 25°C remains to be measured and should be added to the approved commercial specification once confirmed.
Storage
Final storage temperature and shelf-life statements should be added from the approved TDS / MSDS.
TECHNICAL QUESTIONS
FAQ.
This sample uses only supported product specifications and keeps dosage/performance claims application-dependent until field or lab data are supplied.
The current parameter sheet specifies 49.5–50.5 wt.% active content.
The current parameter sheet lists dynamic viscosity at 25°C as to be measured.
Yes. The supplied parameter sheet describes the grade as water-soluble.
Clear to pale-yellow liquid with mild amine odour.
The current parameter sheet gives pH 9–10.5 at 25°C.
A fixed dosage is not stated in the supplied parameter sheet. Dosage should be established using inlet H₂S, flow, contact conditions and the required outlet target.
It can be presented as a metered-injection treatment concept, but the exact injection design must be qualified for the actual process.
Calculated density is 1.101 g/mL at 25°C.
Calculated specific gravity is 1.110 at 25°C/25°C.
Not in the supplied parameter sheet. Shelf life should be added only from the approved current TDS or commercial specification.
NEED H₂S-60 FOR YOUR STREAM?
Share inlet H₂S, flow, pressure, temperature, gas/liquid phase and outlet target. That information is needed to design a meaningful qualification program.
