Output, purity and pressure

Note:

• All pressures which are not specially defined are the gauge pressures
• Nm³/h is defined as the volume at standard atmospheric pressure.
• The liquid output is calculated on the base of data of gas, and the pressure is calculated with 0 meter high at outlet of cold box.

Description:

In liquid oxygen working condition, the supplement nitrogen from nitrogen pipeline mixing with the refluxed gas from liquefier after throttled, and after compressed through circulation nitrogen compressor, it is divided into two streams: one enters main heat exchanger to be cooled, and then it is fed into the high temperature expander where it is expanded, following which it goes out of cold box after being re-warmed in main heat exchanger, and goes back to the inlet place of circulation nitrogen compressor; the other one goes into the main heat exchanger following being boosted in the boosting ends of high temperature expander and low temperature expander to be boosted, part of which is led into the low temperature expander where it is expanded, and then it goes out of cold box after re-warmed in the main heat exchanger, and back to the inlet place of circulating nitrogen compressor; rest part is directly liquefied to liquid nitrogen.

The liquid nitrogen is divided into two streams after being sub-cooled in liquid nitrogen sub-cooler, one stream goes into the oxygen heat exchanger first, and then goes out of cold box after re-warmed, and back to the inlet of circulation nitrogen compressor; the other stream backflows to the LIN sub-cooler after being throttled, and goes out of cold box after re-warmed.

The gaseous oxygen is liquefied by liquid nitrogen in the oxygen heat exchanger, and then it is sent out of cold box.

In liquid nitrogen operating mode, he supplement nitrogen from nitrogen pipeline mixing with the refluxed gas from liquefier after throttled, and after compressed through circulation nitrogen compressor, it is divided into two streams: One flows into high temperature expander to be expanded following being cooled in the main heat exchanger, and then goes out of cold box after being re-warmed in main heat exchanger, and back to the inlet position of circulation nitrogen compressor; the other one enters into the main heat exchanger following being boosted in the boosting ends of high temperature expander and low temperature expander to be boosted, part of which is led into the low temperature expander where it is expanded, and then it goes out of cold box after re-warmed in the main heat exchanger, and back to the inlet place of circulating nitrogen compressor; another part is liquefied to liquid nitrogen directly.

The liquid nitrogen is sub-cooled in the LIN sub-cooler, and then sent out of cold box as product liquid nitrogen after being throttled.

       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. Our products are not only sold well throughout China, but also sold to the West, and our company becomes the designated supplier for several well-known gases investment companies abroad. In the cooperation with transnational large gases companies, our company absorbs and imports the advanced design concept, strict administration program, exquisite manufacturing technology so as to lead our company to develop in the direction of diversification, exquisite products and large-scale. Hangzhou Hangyang Cryogenic Liquefaction Engineering Co., Ltd. undertakes EPC works of ASU under our company.
