Introduction: Ensuring Flow Assurance with Precision MEG Injection

In the oil and gas industry, gas hydrate formation poses a significant challenge, causing blockages in pipelines, valves, and equipment under high-pressure, low-temperature conditions, particularly in offshore and subsea operations. Monoethylene Glycol (MEG) is a widely used hydrate inhibitor, critical for preventing hydrate formation, ensuring flow assurance, and protecting infrastructure.

Premix Technologies, based in Ahmedabad, Gujarat, India, specializes in designing and manufacturing MEG Chemical Injection Packages for gas and oil systems. Our systems provide ultra-precise MEG dosing, safe chemical handling, and compliance with stringent industry standards. With expertise in agitator technology, pump selection, and system integration, we deliver reliable, efficient solutions for upstream, midstream, and downstream applications, ensuring operational safety and flow assurance.

Why Choose Premix Technologies for Your MEG Chemical Injection Package?

Partnering with Premix Technologies guarantees access to advanced engineering and a commitment to precision, safety, and compliance. Our MEG Chemical Injection Packages are distinguished by:

Precision Dosing for Effective Hydrate Prevention

  • Accurate MEG Delivery: Our systems provide precise dosing of MEG (10-50% v/v) tailored to specific flow rates and operating conditions. API 675-compliant dosing pumps ensure high-pressure, low-flow accuracy for optimal hydrate prevention.
  • Homogeneous MEG Preparation: Integrated agitators, designed with advanced mixing calculations, ensure uniform blending of MEG in storage tanks, preventing stratification and ensuring consistent feed to the dosing pump, critical for viscous MEG solutions.
  • Optimized In-Line Mixing: Post-injection, our packages incorporate static mixers or dynamic blending solutions to ensure rapid, uniform dispersion of MEG into the gas or oil stream, maximizing hydrate prevention efficacy.

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, Duplex SS, PTFE, Viton) compatible with MEG, preventing corrosion, contamination, or 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 MEG handling. 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 flow assurance protocols.

Superior Reliability and Operational Efficiency

  • Continuous Duty Operation: Engineered for 24/7 operation in demanding environments like offshore platforms or gas processing plants, our systems maintain consistent MEG 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, MEG 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 gas/oil flow rates, MEG 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

Key Applications:

Premix Technologies’ MEG Chemical Injection Packages are critical across the oil and gas supply chain:

  • Offshore Platforms: Prevents hydrate formation in subsea pipelines and production systems under high-pressure, low-temperature conditions.
  • Gas Processing Plants: Ensures flow assurance by injecting MEG into gas streams during processing or compression.
  • Pipelines (Midstream): Protects long-distance gas or multiphase pipelines from hydrate blockages, ensuring uninterrupted transport.
  • Upstream Production: Supports hydrate prevention in wellheads, flowlines, and separators in onshore and offshore fields.
  • LNG Facilities: Maintains operational integrity by preventing hydrates in liquefied natural gas processing and storage systems.
