Typical Product: KDN-4000 Liquid nitrogen generator

Output, purity and pressure

Description:

This plant employs molecular sieve to purify air, waste nitrogen backflow expansion process.

The air removed with particle impurities goes into molecular sieve after being compressed in compressor. Then it goes into main heat exchanger to reduce temperature gradually until to the saturated temperature, following which it goes into nitrogen column for rectification.

The air is condensed in the nitrogen column continuously, by which the nitrogen content grows up, and obtain product at the top of nitrogen column. At the same time part nitrogen drawn from the top to main heat exchanger for being rewarming, and then sent to the client.

The rest nitrogen at the top goes into condenser evaporator to be condensed to liquid nitrogen which goes back to nitrogen column to follows rectification. The oxygen-rich liquid air at the bottom is throttled to liquid air subcooler to be evaporated to oxygen-rich air which drawn from the top to main heat exchanger to be rewarmed, and then it is drawn from the middle of main heat exchanger to turbo expander.

Oxygen-rich air out of cold box after being rewarmed in main heat exchanger, part of which is as the regeneration gas of MS, the rest is blown off.

Applications:

• Automotive and transportation equipment
• Petroleum and natural gas
• Food industry
• Animal husbandry
• Chemical synthesis
• Medical Gas

Competitive Advantage:

• Good quality materials
• Convenient operation and maintenance
• Quick delivery
• Low Maintenance Cost
• Very simple and safe to operate

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.
