Nitrogen Compressor System
Model J24366
Our Nitrogen Compressor Systems feature an electric-driven 5,000 psi nitrogen booster compressor (model H5417B) which feeds two Haskel air-driven gas boosters (model AGD-152) in parallel, all mounted on a carbon steel base frame. The compressor is covered in noise reduction paneling to optimize working conditions.
Benefits
The system will compress nitrogen gas from a boil-off supply (100 to 145 psig) to give a final outlet working pressure as high as 15,000 psi. At 11,000 psi, the outlet flow-rate is 40 scfm based on an air drive pressure of 90 psig and volume up to 140 scfm. At 15,000 psi, the outlet flow rate reduces to 28 scfm with 90 psig air drive.
High-pressure nitrogen from a Haskel Nitrogen Booster Compressor simultaneously feeds the test outlet via a bypass circuit and pre-charges the Haskel air-driven booster circuit. When the outlet pressure reaches 4,800 psi, Haskel’s AGD-152 gas boosters are switched on automatically and the pressure increases up to the final test pressure controlled by the outlet air pilot switch setting.
Applications
- Nitrogen Gas Pressure Testing - Haskel air-driven gas compressors are used to pressurize a wide range of gas pressure-maintaining devices both on and offshore. Anything from relief valves, pipe spools, and small pressure vessels are tested with nitrogen gas to prove they are leak tight before being put into service on gas production facilities.
- Nitrogen Gas Accumulator Charging - Nitrogen compressors are used for charging nitrogen filled accumulators and pulsation dampeners. As pressure increases within the industry, the need for higher pre-charge on gas accumulators becomes more commonplace. Often, the gas pressure supply from commercially filled gas cylinders is in excess of 500 bar (7,200 psi), lower than the pre-charge required. Haskel gas boosters have the capability to charge to pressures in the region of 1,000 bar (14,500 psi) advantageously using most of the gas in the supply cylinder.
- Barrier Gas Seal - Nitrogen gas is typically used as a gaseous buffer on some gas-lubricated mechanical seals. The buffer gas prevents process leakage to the atmosphere, can prevent ice in low temperatures and helps avoid reaction of product leakage with the air. In high-pressure pumping applications, the buffer media needs to be at a higher pressure than the process fluid. Haskel gas boosters are widely used to boost the low-pressure nitrogen gas, automatically adjusting to the demand and providing a buffer gas to the seal.
- Multi-Booster Nitrogen Gas Booster Systems are ideal for nitrogen gas generators and enabling storage within high pressure gas cylinders. In periods of low demand, surplus gas can be transferred and boosted into high-pressure storage vessels where it can be kept and ready should gas be required to shut down the facility safely. The high-pressure storage can also be used to maintain production during routine maintenance of the nitrogen supply plant.
