Output, purity and pressure

Description:

This is a full low pressure process in which the air is purified by MS with low temperature chiller and boosting turbine expansion. One set of low temperature chiller and two expanders are added to supply cold capacity to liquid product.

The air after purified is divided into 3 parts, the air cooled by chiller with temperature of -30℃ flows into main heat exchanger again, and it is divided into 2 parts: one part flows into expander 1 to be expanded, and then flows into plate-fin to be rewarmed, and then flows to the inlet of air compressor; the other part is continuously cooled and throttled in the plate-fin, and then flows to lower column.

With preliminary rectifying in lower column, liquid air and LIN are obtained from bottom and top of lower column separately. Lair, waste LIN and LIN from lower column is subcooled in Lair/LIN subcooler E2, and then fed to upper column to be rectified further. Then LOX with purity of 99.6% is obtained at bottom of upper column. The required output of LOX is withdrawn out of cold box to LOX storage system of client.

LIN with purity of 2ppmO2 withdrawn from bottom of lower column is subcooled in Lair/LIN subcooler, then required output of high purity LIN is withdrawn out of cold box to LIN storage system of client.

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.
