Skid-Mounted Special Heavy-Duty Screw Associated Gas Compressor for Oil and Gas Recovery Industry
Product Spotlights
Heavy-Duty Screw Compressor Solutions for Global Oil & Gas Applications
This heavy-duty skid associated gas compressor is a complete packaged system for oilfield associated gas recovery and boosting. The large vertical vessel on the skid is the gas-liquid separator, which removes oil droplets, free water and solid impurities from raw associated gas before gas enters the compression host, protecting compressor core components. Working principle: Raw associated gas flows into gas-liquid separator to separate liquid phase and solid impurities. Purified gas enters multi-stage compression host for gradual pressurization. After compression, gas passes through cooling and separation treatment, and is delivered to downstream gathering pipeline. The whole process is automatically monitored and adjusted by explosion-proof PLC control system. Application Fields: Oilfield wellhead associated gas recovery, gas gathering station pressurization, flare gas reduction, low-carbon resource utilization of scattered associated gas, suitable for onshore oil field and offshore land-based oil gathering projects.

Product Advantages
1. Integrated Skid Design: All equipment, piping, valves, electrical and instrument systems are pre-assembled on one steel skid. Factory pre-commissioning shortens site installation cycle, reduces field construction work.
2. High-standard Welding & Quality Control: Thousands of pipe welds are implemented by classification society certified welders, full non-destructive testing to guarantee zero-defect piping system, adapt to long-term high-pressure gas operation.
3. High-shield Multi-core Instrument Cables: Adopt high-grade multi-core shielded twisted cables for signal transmission, effectively block electromagnetic interference in oilfield site, ensure stable and accurate signal transmission for control & measuring instruments.
4. Full Explosion-proof Electrical System: Control cabinet with long-cycle customized programming and explosion-proof structure design, all electrical components comply with UL and IEC explosion-proof standards, suitable for Zone 1 hazardous oil & gas area.
5. Built-in Gas-liquid Separation: Integrated vertical gas-liquid separator removes liquid and solid contaminants in advance, protects compression host and extends service life.
6. Strong Environmental Adaptability: Anti-corrosion coating and optional corrosion-resistant alloy piping, can operate steadily under high humidity, salt mist and corrosive gas environment.
7. Automatic Intelligent Control: PLC control system realizes automatic adjustment, alarm, interlock protection, remote data access, support unattended operation.
8. Green Energy Recovery: Recover associated gas which would otherwise be flared, turn waste gas into usable resource, reduce carbon emission.
Optimized Application Scenarios
Operating in demanding onshore and offshore oilfields requires gas compression systems that you can rely on around the clock. Our heavy-duty screw compressor packages are engineered to tackle real-world field challenges while meeting strict environmental regulations.
Minimizing Emissions & Vapor Loss: In upstream and midstream production sites, our Vapor recovery unit (VRU) screw compressor systems are widely utilized to capture stock tank vapors and prevent harmful emissions.
Tackling Low-Pressure & Flaring Challenges: For mature or low-pressure fields, our low pressure associated gas compression and casing gas recovery compressor units deliver powerful suction performance—effectively eliminating wasteful gas flaring and maximizing overall resource utilization.
Enhancing Field Productivity: We provide robust solutions tailored for enhanced oil recovery (EOR) gas compressor demands and seamless onshore oilfield gas booster system integrations to maintain steady pipeline pressure.
Built for Extreme Industrial Environments: Every API 619 screw compressor package is custom-engineered for maximum safety and durability. Whether you require an ex-proof screw compressor for oilfield safety, a highly resilient sour gas screw compressor built to handle corrosive $H_2S$ and $CO_2$ streams, or a dependable heavy-duty process gas screw compressor for continuous 24/7 duty, we deliver systems built to perform in the harshest conditions.
