Small air separation plant Industry Gas

Typical Product

Output, purity and pressure

Notes:1. Nm³ is based on 0.101325MPa(A),0℃.

2. Output and pressure of product gases are measured at the battery limit of plant, temperature range: 20～40℃.

3.The plant can be running in design mode with adjustment of 50-110%.

Process Description:

The whole VPSA is consisted of blower, vacuum pump, switch valve, adsorber, oxygen balance tank, oxygen booster and oxygen storage tank. Following the elimination of dust particles from feed air at the in the suction inlet filter, the feed air is boosted to 49-58 Kpa by roots blower, and after being cooled by subcooler, it enters into one adsorber, in which filled with adsorbent. The moisture, CO2 and other small amount gas component are adsorbed at the adsorber inlet by the activated aluminium oxide and molecular sieve filled at the bottom. While the oxygen (including argon) which are non-adsorption component goes out from the outlet at the top of adsorber, and then it is fed to the oxygen balance tank as product gas.

When the adsober conducts the adsorption to a certain degree, and the adsorbent will reach saturation condition, use vacuum pump to vacuumize the adsorber (be opposite with the adsorption direction), and the vacuum degree is -50-60 Kpa. The adsorbed moisture, CO2, nitrogen and other small amount gas component will be withdrawn and discharged to the atmosphere, and the adsorbent will be regenerated. Each adsorber conducts the following steps in switch:

---Adsorption

---Desorption

---Pressing

The above three basic process steps will be automatic controlled by PLC and switching valve system.

Applications:

PAS (Pressure Swing Adsorption) has been widely applied in the petroleum, chemical industry, metallurgy, electron, national defense, medical treatment and environmental protection, etc.

Competitive Advantage:

1. Low power consumption
2. High product purity, and can be adjusted flexibly
3. The process is simple, and can separate various gases without complex preprocessing procedure.
4. The plant is controlled by computer, which has advantages of high degree of automation, easy operation, and can achieve full automatic operation.
5. Small investment, low operation cost, easy maintenance, less maintenance time and high rate of operation
6. Long service of adsorbent
7. High reliability of the plant
8. Good environmental benefit

       Hangyang Cryogenic Liquefaction Equipment Co., Ltd. is one of the holding subsidiaries of Hangyang Co.,Ltd.(stock code:002430), it is organized on the basis of the original Small Scale of ASU Company of Hangzhou Hangyang Co,.Ltd. It is the major engineering, research and manufacturing base for small size of ASU and liquefaction plants in China, It is located in Hangyang Manufacturing Base in Lin'an Economic Development Zone, the address of sales office is No. 592, Zhongshan North Road, Hangzhou. It undertakes engineering consulting, design and manufacture, assembled construction design, installation and commissioning and supply of parts for medium and small size of ASU with its professional quality. It is the main base of design, research and manufacture for the domestic medium and small size of oxygen/nitrogen generating plants, liquid oxygen/liquid nitrogen plants, oxygen/nitrogen liquefiers, high-purity nitrogen generators, vacuum pipes and Pressure Swing Adsorption (PSA) for oxygen/nitrogen generating, etc.; Meanwhile, it is also the professional manufacturer for integrated assembly or skid type of medium size of ASU for leaving workshop by Hangyang, its abilities of design and manufacture for integrated assembly of medium size of ASU reach the leading domestic level. Our company has the independent import and export trade qualification.

      Our company possesses professional technical personnel teams of design and EPC engineering of ASU and also possesses design ability of product such as independent process calculation, project design, unit design, project EPC. The manufacture base of our company was relocated to new site in 2009. Recently, the floor area is 40.34 acres. Combinating with relocation, the imported and set-up professional manufacture production tools, moulds and equipment forms the manufacture ability for manufacture ASU whose capacity is below 30,000Nm3/h. Our company carries out the international administration concept and obtains authentication certificates of management system such as ISO9001, ISO14001 and OHSAS18001 of DET NORSKE VERITAS. Meanwhile, we obtains manufacturing license for pressure vessels manufacture D1 and D2, Zhejiang new high-tech enterprise certificate and small and medium-sized technology-based enterprise certificate, our company possesses impeccably professional manufacturing credentials for medium and small size of ASU.   

     Our company sets product research, manufacture, marketing and service in one to elaborately provide general customers superiorly coordinated service on the basis of decades experience in design and manufacture and administration concept by Hangyang. Products involve aspects such as metallurgy, petrifaction, electron, machinery, building materials and aerospace.
