ZC Series Vacuum Degasser for Oil & Gas Drilling Solids Control
Professional Degassing Solutions for Drilling Operations
The ZC series Vacuum Degasser from Zhongcheng Machinery is an essential specialized device for oil and gas Solids Control Systems. It is professionally designed to process gas-cut drilling fluids with exceptional efficiency. This equipment achieves a remarkable degassing ratio of over 95% while handling capacities between 240 and 360 m³/h.
Our system features a compact structure and high integration design. This enables seamless matching with various mud recycling and purification systems. The unit is certified under ISO 9001/14001/45001 quality standards and approved by TÜV and BV.
Whether you're managing conventional drilling projects or specialized shale gas and CBM operations, our vacuum degassing solution delivers reliable performance. It restores mud density quickly and protects your downstream equipment from cavitation damage.
Your drilling fluid enters a vacuum chamber where negative pressure creates an optimal environment for gas separation. According to Boyle's Law, the pressure drop causes entrained gas bubbles to expand rapidly.
This expansion allows harmful gases like methane, H2S, and CO2 to break free from the liquid phase. The vacuum pump extracts these gases efficiently. Meanwhile, the degassed mud exits the chamber with restored density and rheological properties.
The system operates continuously during drilling operations. It processes returned mud before it reaches your active tanks. This prevents gas-cut mud from compromising your entire circulation system and creating potential safety hazards.

Core Advantages for Your Drilling Operations
Efficient Gas Removal Performance
Your drilling safety depends on rapid gas removal. Our system quickly eliminates harmful gases from drilling fluids to prevent blowout risks. The high-speed centrifugal spraying creates a thin film distribution that maximizes gas liberation even in high-viscosity fluids.
Excellent Corrosion Resistance
Oilfield environments are harsh and demanding. Our equipment features corrosion-resistant internal coatings that withstand H2S-rich mud and acidic conditions. NACE MR0175 compliant materials are available for sour gas applications.
Compact and Integrated Design
You need equipment that fits your existing systems. Our compact footprint integrates seamlessly with all types of mud recycling configurations. The high integration design eliminates the need for external air sources or complex piping modifications.
Simple Operation and Maintenance
Your crew can operate this system with minimal training. The straightforward design reduces maintenance requirements significantly. Regular maintenance primarily involves monitoring seal-water supply for the vacuum pump to prevent impeller scaling.

Industry Applications and Use Cases
Oil and Gas Exploration
In deep-well and high-pressure drilling scenarios, the Vacuum Degasser serves as your primary defense against gas kicks. It processes returned mud continuously to maintain proper density control. This ensures wellbore stability throughout your drilling operations.
Shale Gas and CBM Development
Unconventional resource extraction presents unique challenges. Gas-rich formations require aggressive degassing to maintain fluid properties. Our system handles these demanding conditions while protecting your centrifugal pumps from cavitation damage.
Horizontal Directional Drilling (HDD)
Complex tunneling environments introduce air pockets into your drilling slurries. Accurate mud-weight management is critical for successful navigation. The degassing unit removes these air pockets to ensure recycled fluid integrity and steering accuracy.

Frequently Asked Questions
Q: How does mud viscosity affect degassing efficiency?
A: High viscosity can slow bubble migration in conventional systems. However, our high-speed centrifugal spraying creates a thin film that neutralizes viscosity resistance. This maintains efficient gas separation even in heavy mud conditions.
Q: What are the primary maintenance requirements?
A: For water-ring pumps, maintaining a clean seal-water supply is critical. This prevents impeller scaling and overheating issues. Regular inspection of vacuum seals and discharge lines also helps maintain peak performance.
Q: Can your system handle H2S-rich drilling mud?
A: Yes, our units can process sour gas applications safely. We use NACE MR0175 compliant materials for corrosive environments. Specialized vent-line routing ensures operator safety when handling toxic gases.
Q: Why might the unit experience priming issues?
A: Priming problems typically indicate a vacuum leak in the suction line. Improper height differential between the inlet and mud tank level can also cause issues. Our technical team can quickly diagnose and resolve these situations.
Q: How do you verify actual degassing performance?
A: Efficiency verification uses comparative mud-density testing before and after processing. A pressurized mud balance measures actual density to confirm all entrained gas removal. We recommend regular testing during commissioning and periodic operations.
Q: What customization options are available?
A: We offer flexible customization of dimensions, motor brands, and configurations. You can choose between domestic and international motor suppliers. Explosion-proof ratings can be matched to your specific hazardous area classifications.
