Description:
This plant employs a process in which the air is purified by molecular sieve, expansion turbine is provided with braking effected by fan and nitrogen is produced by means of double columns with expansion accomplished through drag flow. PFD as follows:
Applications:
- Welding and metal processing
- Food industry
- Depth refrigerant
- Animal husbandry
- Process Gas
- Nitrogen and Helium Leak Test
Competitive Advantage:
- By means of single column with expansion accomplished through backflow, which can supply nitrogen gas with medium pressure directly without compression in backward nitrogen compressor, which not only cuts down cost, but also prevents secondary pollution, as well as reduces power consumption.
- The stress is analyzed and strength is calculated in details for the cold box in fractionating column system in accordance with the client’s local meteorological and geological conditions to ensure the safety of cold box. The stress is analyzed for the main pipelines located in cold box.
- The aluminum alloy material with high strength is used to fabricate these pipelines to keep them non-deformable. The 3 kinds of supports in cold box are made of stainless steel such that the strength at low temperature can be ensured and the loss in heat conduction is reduced. The valves in the cold box are manual controlled.
- All pressure vessel of this nitrogen plant is designed and manufactured in accordance with ASME specifications for long, stable and reliable running, economization of energy, convenient operation and maintenance.
- Engineers available to service machinery overseas
