Oilfield Chemicals

Our company engages in the R&D and mass production of high-efficiency oilfield chemicals applicable to oil and gas gathering & transportation systems. Our core products include triazine desulfurizer, triazine bactericide, oilfield demulsifier and corrosion inhibitor. These chemicals effectively remove hydrogen sulfide, restrain bacterial reproduction, separate crude oil from emulsion and slow down pipeline corrosion. They stabilize oilfield production flow, cut operational loss and extend the service life of gathering pipelines and surface facilities.

Oilfield Chemicals Manufacturer

Huadingcheng is an oilfield chemicals manufacturer supplying production chemicals for oil and gas wells, gathering systems, transportation pipelines, produced-water treatment and surface processing facilities.

Our portfolio covers four common production challenges: hydrogen sulfide removal, microbial control, crude oil dehydration and corrosion protection. These oilfield chemicals are supplied to oilfield service companies, production operators, chemical distributors and project procurement teams requiring consistent bulk supply and application-oriented product selection.

Oilfield Production Chemicals

Product	Function and Application
MEA Triazine H2S Scavenger	Water-soluble triazine-based chemical for removing hydrogen sulfide from produced fluids, natural gas gathering systems, wellheads, pipelines and storage facilities.
HHT Triazine Biocide for Oilfield Water	HHT, also known as MEA triazine, used as a broad-spectrum biocide for produced water, water injection systems, gathering pipelines and storage tanks.
Crude Oil Demulsifier	Polyether-based chemical for breaking oil-water emulsions, improving dehydration, reducing basic sediment and water, and supporting separator and desalting operations.
Oilfield Imidazoline Corrosion Inhibitor	Imidazoline-based inhibitor that forms a protective film on metal surfaces exposed to H₂S, CO₂, chloride and high-salinity produced fluids.

H₂S Scavengers for Oil and Gas Production

Hydrogen sulfide creates safety, corrosion and gas-quality risks across upstream and midstream operations. A triazine H₂S scavenger reacts chemically with H₂S and converts it into stable water-soluble reaction products.

Huadingcheng supplies different active-content grades, including TS-40, TS-60 and TS-78, for different H₂S concentrations and treatment conditions. The product can be injected into produced fluids at the wellhead, applied at gas gathering stations or used upstream of processing equipment.

Typical application points include:

Oil and gas well production fluids
Wellheads and flowlines
Natural gas gathering pipelines
Crude oil storage tanks
Pre-treatment before downstream gas processing

The required dosage should be determined from actual H₂S monitoring, fluid composition, gas-liquid contact and residence time.

Triazine Biocide for Produced Water

Oilfield water systems can support sulfate-reducing bacteria, acid-producing bacteria and iron bacteria. These microorganisms may contribute to biofilm formation, microbiologically influenced corrosion, iron sulfide deposition and secondary H₂S generation.

The HHT triazine biocide is designed for microbial control in:

Produced-water treatment systems
Water injection facilities
Gathering and transportation pipelines
Crude oil storage tanks
Industrial circulating-water systems

Although HHT triazine is chemically related to the triazine H₂S scavenger, the two products serve different purposes. The scavenger is used for direct H₂S removal, while the biocide is used to control microbial growth. Product selection should therefore be based on H₂S measurements, bacterial counts and the treatment objective.

Local chemical registration, transport classification and discharge requirements should be confirmed before field use.

Crude Oil Demulsifiers for Oil-Water Separation

Water and oil can form stable emulsions during production, gathering and transportation. If the emulsion is not properly treated, it can increase heater and separator loading, delay dehydration and raise the water content of crude oil.

Our crude oil demulsifier range includes:

Water-soluble demulsifiers for high-water-cut produced fluids
Oil-soluble demulsifiers for low-water-cut crude and pipeline applications
Formulation options for light, medium, heavy and polymer-flooded crude

Demulsifier performance is highly dependent on crude properties. Bottle testing with representative field samples is recommended to compare water separation rate, interface clarity, residual water and oil-in-water content before full-scale injection.

Imidazoline Corrosion Inhibitors

Oilfield production systems may be exposed to H₂S, CO₂, chloride, brine and acidic fluids. These corrosive media can attack tubing, gathering pipelines, separators, storage tanks and water-injection equipment.

The imidazoline corrosion inhibitor adsorbs onto the metal surface and forms a hydrophobic protective film. Water-soluble and oil-soluble grades are available for different fluid phases and injection points.

Applications include:

Sour oil and gas wells
CO₂ and enhanced-oil-recovery systems
Crude oil gathering pipelines
Produced-water and water-injection lines
Surface production and processing equipment

The appropriate inhibitor depends on metallurgy, water cut, temperature, flow velocity, H₂S or CO₂ partial pressure and the presence of other oilfield production chemicals.

Frequently Asked Questions

What is the difference between an H₂S scavenger and a triazine biocide?

An H₂S scavenger reacts directly with hydrogen sulfide to reduce its concentration. A triazine biocide controls bacteria that may generate H₂S, biofilm or microbiologically influenced corrosion.

Is HHT triazine the same as MEA triazine?

HHT triazine and MEA triazine are commonly used names for hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine. The final product application and formulation should still be confirmed through the technical data sheet.

How is a crude oil demulsifier selected?

Selection depends on crude density, viscosity, water cut, temperature, emulsion type and separator conditions. Bottle testing with actual field crude is recommended before continuous injection.

What is the difference between water-soluble and oil-soluble corrosion inhibitors?

Water-soluble corrosion inhibitors are generally used in produced-water and water-injection systems. Oil-soluble grades are more suitable for crude oil, hydrocarbon and gas-gathering systems.

What information is needed for a bulk quotation?

Please provide the product type, required active content or grade, estimated quantity, packaging preference, delivery destination and any available field test data or technical specification.
