Compressor Systems for Offshore Oil & Gas Production

Product catalog summary

Overview
Gardner Denver Nash specializes in designing compressor systems for offshore oil and gas production, with a focus on liquid ring compressors. Their expertise includes handling various hydrocarbons and external factors to ensure continuous operation and meet customer expectations.

Key Projects
The Gjøa Platform in the North Sea features a NASH NAB 1500 two-stage liquid ring compressor, designed for a flow rate of 1500 m3/h and a discharge pressure of 6 to 9 bar absolute.

Technology and Experience
With over 50 years of experience, Gardner Denver Nash provides reliable compressors and vacuum pumps, known for their rugged design, low maintenance, and ability to handle explosive gases. Their technical staff and global value-added centers ensure compliance with industry standards like API681, NEMA, IEEE, and ATEX.

Product Features
NASH liquid ring compressors offer reliability, lower operating and maintenance costs, and environmental compliance. They are used for gas compression, vapor recovery, and glycol recovery systems on offshore rigs.

Deaeration and Deoxygenation
NASH vacuum pumps and air ejectors are used for removing oxygen from well injection water to prevent corrosion and bacterial growth. These systems are available in materials like Stainless Steel, Aluminum Bronze, and Hasteloy for harsh offshore conditions.

Liquid Ring Pump Design
NASH introduced conical rotor porting in the 1940s, which improves efficiency and reliability over flat-sided designs. These pumps handle carryover, require no internal lubrication, and are ideal for explosive gases.

Offshore Applications
NASH compressors are used for flare gas recovery, vent gas recovery, and glycol recovery, helping companies meet environmental regulations and recover valuable hydrocarbons.

Service and Support
Gardner Denver Nash offers professional service and support through service centers in multiple countries, ensuring long-term operation of their pumps and compressors.

Additional Products
NASH offers a range of liquid ring vacuum pumps and compressors, including models with superior corrosion resistance, self-recirculating seal water, and the ability to handle high back pressure requirements.

NASH Liquid Ring Pumps Deaeration/Deoxygenation Deaeration of Injection Water Removal of oxygen from well injection water helps to prevent corrosion and sub-surface solids build-up. This also prevents the formation of aerobic bacterial colonies (sulfur reducing bacteria) in the water injection flow lines. Incoming water is filtered and then sent to Deoxygenation Towers for the removal of oxygen. This process is facilitated by NASH vacuum pumps and an atmospheric air ejector. These pumps and air ejectors are available in Stainless Steel, Aluminum Bronze and Hasteloy for the harsh conditions found...
