Chemical Injection Skid / Package
Advanced Dosing Technology for Flow Assurance & Asset Protection
Our Chemical Injection Skid (Skid-Mounted Package) is engineered to provide precise, automated, and continuous dosing of specialty chemicals into production streams, pipelines, and process systems. Designed for the most demanding environments – onshore, offshore, FPSO, TLP, MOPU, and subsea support – these systems are critical for maintaining operational integrity, enhancing hydrocarbon recovery, preventing flow assurance issues, and protecting capital assets across the upstream, midstream, and downstream sectors.
The skid is a complete “plug-and-play” solution, pre-assembled and factory-tested to significantly reduce on-site installation labor, project lead times, and hazardous work activities.
Core Applications
Our skid-mounted systems inject a wide range of critical chemical agents for the following purposes:
| Application Area | Chemicals Used | Purpose |
| Flow Assurance | Methanol, MEG (Monoethylene Glycol), TEG, Kinetic Hydrate Inhibitors (KHIs) | Prevent hydrate formation in gas lines and subsea flowlines |
| Asset Protection | Corrosion inhibitors, Scale inhibitors, Oxygen scavengers | Mitigate pipeline and downhole equipment degradation |
| Process Optimization | Demulsifiers, De-oilers, Drag reducing agents (DRAs) | Enhance oil/water separation and improve flow efficiency |
| Water Treatment | Biocides, Flocculants, Coagulants, pH regulators | Treat produced water, support enhanced oil recovery (EOR), and ensure water quality |
| Other critical functions | Wax inhibitors, Foam control agents, Antifoulants | Maintain fluid handling and process stability |
Typical Components
A standard chemical injection skid integrates multiple precision components on a common base frame:
- Metering pump(diaphragm or plunger type) – delivers accurate and repeatable chemical volumes
- Chemical storage tank(rectangular or cylindrical) – holds the chemical to be injected
- Multi-compartment tank– available for different chemicals in one skid
- Calibration pot / column– enables verification of pump output and injection accuracy
- Pulsation dampener– smooths pressure fluctuations from reciprocating pumps
- Safety / relief valve– protects the system from over-pressurization
- Back pressure valve– maintains consistent system pressure
- Y-type strainer / suction strainer– removes solid particles from the chemical
- Pressure gauge & instrumentation– provides real-time monitoring
- Control panel– houses automation logic (local PLC with HMI or integration with plant DCS/SCADA)
Additional options: level instruments, flow transmitters, agitators, flame arresters, electric heat tracing, remote monitoring transmitters, and explosion-proof enclosures.
Technical Parameters (Customizable)
| Parameter | Standard Range | Extended / Custom Range |
| Pressure rating | 150 – 30,000 psi | Up to 20 MPa (custom) |
| Flow rate | 1 – 100 L/min | 1 L/h – 1,000 L/h |
| Tank volume | 1 – 10 m³ | On request |
| Injection accuracy | ±1% (API 675 compliant) | – |
| Pump drive | Electric, air, or gas driven | Variable stroke length / frequency drive |
All parameters can be tailored to specific project requirements.
Key Features & Modular Design
- High-precision dosing– Configured with API 675 compliant metering pumps (diaphragm or plunger) to ensure ±1% volumetric accuracy. Injection rate is adjustable via variable pump stroke length or frequency drive of the electric motor.
- Engineered metallurgy– Available in SS316L, Duplex, Super Duplex, Hastelloy, and other corrosion-resistant alloys to handle highly aggressive chemicals, acids, alkalis, and salt media.
- Comprehensive “plug-and-play” integration– Includes storage tanks, suction and discharge line valves, calibration columns, pulsation dampeners, safety relief valves, and all necessary instrumentation.
- Intelligent control options– Local PLC control panels with HMI, or seamless integration into the plant’s main DCS/SCADA system for remote monitoring, real-time data acquisition, and automatic dosing adjustment.
- Hazardous area certification– Certified to international standards including ATEX, IECEx, NEC (Class I, Div 1 & 2), with explosion-proof, moist-proof, and dust-proof ratings available.
- Compact, modular skid-mounted design– Pre-engineered for easy integration into existing infrastructure and space-constrained installations (FPSOs, TLPs, MOPUs, wellhead platforms).
- Bespoke configuration– Each skid is custom-made based on customer specifications, including flow rate, pressure rating, tank capacity, material selection, pump type, and control system requirements.
- Long service life & easy maintenance– Industrial-grade components and robust construction ensure durability with minimized downtime.
Factory Testing & Quality Assurance
Every unit undergoes rigorous testing before deployment:
- Hydrostatic testing– confirms pressure integrity
- Functional acceptance test (FAT)– verifies all system functions
- Non-destructive testing (NDT)– ensures material and weld quality
The skid is delivered fully assembled, tested, and ready for rapid installation and commissioning.
