VPSA-300Nm³/h (N₂) PSA Nitrogen Generator

Output, purity and pressure

Process Description:

Regarding the adsorbed gas (adsorbate) for any adsorbent, under the adsorption equilibrium, the lower temperature, higher pressure, the bigger adsorption capacity. On the contrary, higher temperature, lower pressure, the smaller adsorption capacity. So the adsorption and separation methods of gases usually employ two circulating processes of temperature swing adsorption and pressure swing adsorption.

If the pressure is invariant, under normal temperature or low temperature condition, it utilizes high temperature desorption method, which is called temperature swing adsorption. Due the large specific heat capacity of adsorbent, and small heat conductivity, it needs long time for warming and cooling, and the operation is troublesome. So the temperature adsorption mainly used to purify the gas with less adsorbate.

If the temperature is invariant, under the condition of pressuring, it utilizes decompression or normal pressure desorption method, which is called pressure swing adsorption. It is obvious that pressure swing adsorption conducts adsorption and desorption through changing pressure.

Applications:

We supplied many countries (USA, Germany, Mexico, Indonesia, North Korea, Kazakhstan, Iran, Saudi Arabia, Egypt, Brazil, Hungary, Malaysia, Czech, Switzerland, Spain, Myanmar, Vietnam, Thailand, Russia, Mongolia, Syria, India, etc.)

Competitive advantage:

1. The Seller will provide the related technical documents, like pressure vessel certification, operation manual.

2. The Seller will provide the technical guidance for plant installation, and be responsible for the commissioning of the plant and training for operator.

3. When finishing the manufacturing of complete plant, it can be delivered only after all technical indexes are qualified after being tested.

4. All valves will be tested, the safety valves of vessels and electrical part will be detected.

5. The company established common spare parts storage to adequately assure the various demands of user.

       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.
