Reciprocating Gas Compressors

Blackmer NG series

BLACKMER NG Compressors - Natural Gas Compressors

Specially designed for the oilfield, the BLACKMER NG Series Reciprocating Gas Compressors have proven themselves over and over as dependable and robust equipment for oil and natural gas production, vapor recovery and storage operations. These oil-free reciprocating gas compressors are constructed and equipped with superior components, which help provide maximum performance and reliability under the most severe service conditions. BLACKMER NG Series Reciprocating Gas Compressors are highly efficient, heavy duty single- and two-stage oil-free compressors. Each BLACKMER NG Series Compressor is constructed with a single distance piece between two sets of seals on each piston rod. The distance piece provides leakage control and prevents oil contamination of the compressed gas stream. Ports are provided in the distance piece chamber for purging, pressurizing or venting. This enables NG Series Compressors to be utilized in a wide range of wellhead applications for oil-and-gas production and storage operations. Additionally, NGS Series Sour Gas compressors can handle liquefied gases with up to 8% dry hydrogen sulfide (H2S) content

Specific features of the NG Series Compressors include:

Advanced Engineering and Material Benefits:
 
• Corrosion-Resistant Design: No yellow metals (brass or copper) are used, enhancing corrosion resistance in harsh environments.
• High-Performance PTFE Piston Rings: Self-lubricating and pressure-assisted for maximum sealing efficiency with minimal friction and wear.
• Durable Steel Wrist-Pin Bearings: Needle bearings ensure extended life under high rod-load conditions, with consistent lubrication at all loads.
• Leakage Control Isolation Chambers: Single-distance pieces separate the crankcase lubricant from the compression chamber to maintain oil integrity.
• Robust Sealing Technology: All pressure-containing components are sealed with FKM or PTFE O-rings for reliable performance in all operating conditions.
• High-Efficiency Valve Design: Valves and plates made from self-lubricating PEEK material deliver excellent sealing, efficiency, and durability; stainless-steel valve options are also available for specialized applications.

Wherever wellhead gases need to be efficiently managed, Blackmer NG Series Gas Compressors are the most preferred choice

Trusted Reliability Backed by Decades of Industry Expertise

With decades of proven experience in the oil and gas industry, Blackmer has built a strong reputation for product innovation, superior quality, and—most importantly to Wellhead Operators—unmatched reliability. Designed to perform in the most rugged and remote unmanned locations, Blackmer NG Gas Compressors are trusted by professionals to deliver consistent, failure-free operation at the wellhead and storage tank batteries across a wide range of critical applications.

Annulus Reduction

Blackmer NG Compressors have different options, like to reduce wellhead gas pressure improving oil flow into underground tanks for more cost-effective oil production enhancement.

Vapor Control

The wellhead and tank batteries are the two major sources of fugitive methane emissions. Common air compressors lack critical seals to prevent gas leakage and crankcase oil dilution. Condensate can form in the compressor, which will contaminate crankcase oil. Condensate will break down the oil acting like a solvent, stripping bearings of critical lubrication. The result is damaging heat, friction, and equipment damage or breakdown. Blackmer NG Compressors are specially designed to capture and control wellhead gases. The design prevents gas leakage and oil contamination.

Vapor Recovery

Increasingly stringent state and federal clean air rules are promoting the reduction and elimination of gas venting and flaring of fugitive gas emissions. Blackmer NG Compressors are unsurpassed in reducing emissions and the recovery of saleable wellhead gas, thus protecting the environment, supporting regulatory compliance and improving the bottom line

Product Transfer

Blackmer NG Compressors move wellhead and tank battery vapors into low to medium pressure pipelines where it can be further processed downstream at a gas processing station. Wellhead operators attest to the importance of equipment reliability and uptime performance, and understand the risks and downtime costs of relying upon less capable, less durable air compressors. They avoid the unnecessary expense of daily and weekly oil changes, and the frequent replacement of these less durable compressors. They recognize the Blackmer product outlasts and outperforms, requiring only routine maintenance. Its ability to remain on 24/7/365 continuous duty for the long haul is testimony to Blackmer reliability and bottom line results.

Compressor Selection Guidance

To choose the NG Series Compressor that best meets your specific application requirements, refer to the provided selection charts. Please note that actual performance may vary based on line restrictions, as well as the size and length of the piping used. Horsepower requirements for both liquid transfer and vapor recovery applications are calculated under moderate climatic conditions and may need adjustment for more extreme environments.
