LifenGas - Nitrogen Generator By Pressure Swing Adsorption (PSA)
The PSA Nitrogen Generator utilizes pressure swing adsorption technology to effectively separate nitrogen from oxygen in the air. This process employs carbon molecular sieve adsorbents, derived from high-quality coal, coconut shell, or epoxy resin, to accelerate the diffusion of oxygen over nitrogen into the sieve's pores. Consequently, nitrogen remains primarily outside the adsorbent's structure, allowing it to be collected as a high-purity product. This equipment boasts several technical advantages, such as skid-mounted delivery for quick installation, a compact design, rapid startup time of about 30 minutes, and automated, unmanned operations. Nitrogen purity can be adjusted between 95% and 99.9995% based on requirements. Additionally, the system ensures a lifespan of more than a decade with minimal maintenance, making it ideal for industries like metal treatment, chemical processing, electronics, and food preservation, where high-purity nitrogen is critical.
Nitrogen generator by pressure swing adsorption is the use of a carbon molecular sieve adsorbent processed from high quality coal, coconut shell or epoxy resin under pressurized conditions, the diffusion speed of oxygen and nitrogen in the air into the carbon molecular sieve hole, so as to separate the oxygen and nitrogen in the air. Compared with nitrogen molecules, oxygen molecules first diffuse into the holes of carbon molecular sieve adsorbent, and the nitrogen that does not diffuse into the holes of carbon molecular sieve adsorbent can be used as the product output of gas for users.
- The equipment is skid mounted and delivered and there is no on-site installation work.
- The unit covers a small area and has a short production cycle.
- Starts up quickly and provides product nitrogen for 30 minutes after start-up.
- High level of automation, fully automatic and unmanned operation.
- Simple process, less maintenance.
- Product purity of 95%~99.9995% is optional.
- The equipment has a life span of more than ten years.
- There is no need to fill the molecular sieve during operation.
- After the raw nitrogen (volume oxygen content ~1%) produced by the PSA pressure swing adsorption or membrane separation nitrogen system has been mixed with a small amount of hydrogen, the residual oxygen in the raw nitrogen reacts with hydrogen to form water vapour in a reactor equipped with a palladium catalyst. The chemical reaction formula is 2H2＋ O2→ 2H2O+ heat of reaction
- The high purity nitrogen leaving the reactor is first cooled by the condenser to remove condensate. After drying in the adsorption dryer, the final product is very clean and dry nitrogen (product gas dew point up to -70℃). The hydrogen feed rate is adjusted by continuously monitoring the oxygen content in the high purity nitrogen. The specially designed control system can automatically regulate the hydrogen flow rate and ensure the minimum hydrogen content in the product nitrogen. The on-line analysis of purity and moisture content allows the unqualified products to be automatically discharged. The entire system is fully automated for operation.
