Description:
The process of the plant is that the air is purified by molecular sieve, turbo expander is provided with braking effected by fan and nitrogen is produced by single column with expansion achieved through backflow. The process flow diagram as follows:
Applications:
1. Nitrogen Purging & Pressurize Test
2. Generate Vegetable Maturity Gas
3. Blanketing Gas
4. Balance Gas
5. Standard Gas
6. Food and beverage
7. Depth refrigerant
8. Automotive and transportation equipment
9. Medical Gas
Competitive Advantage:
1. The advanced software introduced from abroad for calculation of performance is used to analyze the optimization of process adopted by this plant. The more advanced program developed by Hangyang itself on the basis of rectification design module from Linde for rectification calculation and verified in many air separation plants is applied to ensure the price proportion of optimum technical/economical figures to fine performance.
2. The plate and fin heat exchangers are brazed by large size vacuum brazing furnace which is the first one in China imported from SW Corp. in USA. The cores vacuum brazed by this furnace are of good quality and in long service life. Hangyang has developed new and efficient fin types in recent years to get the heat exchangers more efficient.
3. 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.
4. Low energy power consumption.
