Oxygen Scavenger Injection Packages for Gas and Oil Systems by Premix Technologies: Precision, Safety, and Compliance

Introduction: Preventing Corrosion with Precision Oxygen Scavenger Injection

In the oil and gas industry, oxygen ingress in water systems can lead to severe corrosion in pipelines, boilers, and equipment, compromising operational integrity and safety. Oxygen scavengers such as sodium bisulfite, hydrazine, or sulfite-based chemicals are essential to remove dissolved oxygen, protecting infrastructure and ensuring system longevity.

Premix Technologies, based in Ahmedabad, Gujarat, India, specializes in engineering and manufacturing Oxygen Scavenger Injection Packages for gas and oil systems. Our systems deliver precise dosing, safe chemical handling, and compliance with stringent industry standards. Leveraging expertise in agitator technology, pump selection, and system integration, we provide reliable, efficient solutions for upstream, midstream, and downstream applications, ensuring corrosion control and operational reliability.

Why Choose Premix Technologies for Your Oxygen Scavenger Injection Package?

Partnering with Premix Technologies ensures access to cutting-edge engineering and a commitment to precision, safety, and compliance. Our Oxygen Scavenger Injection Packages are distinguished by:

Precision Dosing for Effective Corrosion Control

  • Accurate Scavenger Delivery: Our systems provide precise dosing of oxygen scavengers (e.g., sodium bisulfite: 0.1-1% v/v;      hydrazine: 0.05-0.5% v/v) tailored to water flow rates and oxygen levels. API 675-compliant dosing pumps ensure high-pressure, low-flow accuracy.
  • Homogeneous Chemical Preparation: Integrated agitators, designed with advanced mixing calculations, ensure uniform blending of scavengers in storage tanks, preventing sedimentation and ensuring consistent feed to the dosing pump, critical for reactive chemicals like hydrazine.
  • Optimized In-Line Mixing: Post-injection, our packages incorporate static mixers or dynamic blending solutions to ensure rapid, uniform dispersion of scavengers into water streams, maximizing oxygen removal efficiency.

Uncompromising Safety and Regulatory Compliance

  • Hazardous Area Certification: All components (pumps, motors, instrumentation) are certified to ATEX, IECEx, or NEC Zone 1/2 standards, ensuring safe operation in flammable gas and oil environments.
  • Material Compatibility: Through rigorous material selection and corrosion analysis, we use wetted parts (e.g., SS316L, Hastelloy, PTFE, Viton) compatible with oxygen scavengers, preventing corrosion, contamination, or chemical degradation.
  • Comprehensive Safety Features: Systems include pressure relief valves (sized via PSV calculations), leak detection, emergency shutdown (ESD) systems, and multiple interlocks to mitigate risks associated with reactive or toxic scavengers. Structural and skid frame analyses ensure robust, stable designs for safe operation and maintenance.
  • Industry Standards Compliance: Systems adhere to standards such as API 675, API 14C, NACE MR0175 (for sour service), and ISO 9001, ensuring compliance with oil and gas industry requirements and corrosion control protocols.

Superior Reliability and Operational Efficiency

  • Continuous Duty Operation: Engineered for 24/7 operation in demanding environments like offshore platforms or refineries, our systems maintain consistent scavenger injection at flow rates up to 5000 m³/hr or higher.
  • Low Maintenance Design: High-quality, corrosion-resistant components and robust construction minimize maintenance needs, reducing downtime and operational costs in remote or harsh environments.
  • Smart Automation: PLC-based control systems with HMI interfaces enable real-time monitoring of flow rates, scavenger levels, and system status. Automated ratio control, data logging, and alarms ensure precise operation and remote management, with strainer calculations protecting critical components from particulates.

Custom-Engineered, Turnkey Solutions

  • Tailored Design: Each package is customized to client specifications, including water flow rates, scavenger types, dosing concentrations, operating pressures (up to 500 barg), and environmental conditions.
  • Skid-Mounted Modularity: Delivered as compact, self-contained skids, our systems simplify transportation, installation, and integration into existing infrastructure. Piping stress and pressure calculations ensure leak-free, reliable interconnections.
  • Comprehensive Support: From consultation to commissioning, we provide 3D modeling, detailed proposals, and post-installation services, including training and maintenance support, to ensure seamless integration and performance.
