Chemical platforms for sour-gas operations

Control H2S.Protect throughput.

Chemflo develops and validates industrial scavenger chemistry for natural gas and hydrocarbon streams—focused on reaction performance, solids control, system integrity, and the operating conditions that determine field value.

H₂S scavenger platforms

Follow the treatment circuit.

Both platforms move through the same four operating stages: bring in the sour stream, make chemical contact, separate the spent chemistry, and send on-spec sweet gas to the sales line.

SULX-210™

WATER-SOLUBLE
NON-TRIAZINE PLATFORM

How it works

TREATMENT CIRCUIT / SULX-210™
STEP / 01
Sour gas enters

The untreated gas stream enters the contact point carrying the H₂S load that must be removed.

STEP / 02
Chemistry makes contact

The stream contacts SULX-210™, and the non-triazine chemistry reacts with H₂S in the gas.

STEP / 03
Spent chemistry drops out

The reacted, spent chemistry separates from the gas phase so it can be removed from the circuit.

STEP / 04
Sweet gas goes to sales

The treated gas leaves the unit for the sales line after the outlet is confirmed on spec.

SULX-210™ pairs that familiar circuit with a water-soluble, non-triazine formula designed to reduce scaling impact and help avoid pipeline or tower plugging during over-injection and high-H₂S service.

PERFORMANCE / 01

Capabilities

  • Higher H₂S uptake capacity than conventional triazine
  • Faster scavenging kinetics
  • Stronger thermal stability under demanding conditions
OPERATING IMPACT / 02

Advantage

  • Non-hazardous spent chemistry
  • No dithiazine solids formation
  • Reduced solids-control, scaling, and plugging risk

NITX-310™

NITRITE-BASED
CATALYZED PLATFORM

How it works

TREATMENT CIRCUIT / NITX-310™
STEP / 01
Sour gas enters

The untreated gas stream enters the treatment unit with H₂S in the flowing gas.

STEP / 02
Chemistry makes contact

The stream contacts NITX-310™, where the catalyzed chemistry drives the H₂S scavenging reaction.

STEP / 03
Spent chemistry drops out

The reacted, spent chemistry separates and drops out of the treated gas stream for removal.

STEP / 04
Sweet gas goes to sales

On-spec sweet gas exits the treatment unit and moves into the sales line.

NITX-310™ combines nitrite with a patented catalyst system. The platform is designed for high-H₂S service with MEA-triazine-equivalent integrity, solid dispersion, corrosion inhibition, and lower treatment cost.

Performance in operating context

Chemistry is only useful when the system keeps moving.

Chemflo’s development work connects scavenger performance to the realities operators manage: H₂S loading, temperature, over-injection, deposition, corrosion, and downstream restriction risk.

01

Capacity & kinetics

Compare how candidate formulations capture H₂S and how quickly the reaction progresses under defined conditions.

02

Solids & scaling

Evaluate chemistry with pipeline and tower plugging risk, dithiazine formation, and scaling impact in view.

03

Thermal stability

Assess formulation direction against the temperature conditions expected in the intended hydrocarbon service.

04

System integrity

Consider corrosion inhibition, solid dispersion, and treatment cost alongside scavenging efficiency.

Development path

From stream conditions to formulation direction.

A controlled bench program keeps the work anchored to the treatment target and the evidence required for a go/no-go decision.

STEP / 01

Define the stream

Frame the hydrocarbon medium, H₂S challenge, operating envelope, and treatment objective.

STEP / 02

Build candidates

Develop formulations suitable for controlled small-scale evaluation.

STEP / 03

Compare performance

Test candidate formulations and examine results under defined conditions.

STEP / 04

Validate direction

Identify whether a formula warrants further development toward manufacturing.

Technical project review

Bring the operating envelope into the lab.

A useful evaluation begins with the stream, treatment target, and constraints. Those inputs define the test conditions and the performance criteria worth measuring.
