The group of Russian journalists visited Jinan metallurgical complex in China

10.04.2017 In March, the group of Russian journalists visited Jinan metallurgical complex in China, where operated is the rare gases separation unit (URRG) developed and manufactured by PJSC Cryogenmash.

All units were supplied by PJSC Cryogenmash in 2011. Ever since these units were operated without any emergency shutdowns and unforeseen situations. According to Lee Zonghui, Deputy Director of gas plant of Jinan metallurgical complex, it was not required for any SPTA from Cryogenmash within this period.

The unit processes 200 cubic meters of a mixture per hour. The raw material contains 0,269% of xenon and krypton at the URRG inlet. These gases are in massive demand both at domestic and international markets. This unit produces for 960 liters of xenon and 10 800 liters of krypton per day.

The key competitive advantage of Cryogenmash units at the market is the end product with unique purity. According to employees of Jinan gas plant, the gases purity even exceeds the Chinese stringent standard requirements.

Nowadays, the rare gases market demonstrates the promising prospects, as they are widely used, moreover in the most innovative industries. For example, in the medical field, xenon is used extensively for diagnostic medical services and anesthesia, as well as in the space vehicles motors, or as the lasers substance, or as the propellant oxidizing agent, etc. In its turn, krypton is used for manufacture of high-strength double-glazing unit, and for lasers (moreover, for ultrapowerful and battle ones), and for propellant oxidizing agents. Considering the fact that NASA will restructure, but won’t roll back its plans relating to space research and exploration, then rare gases have the promising future. Neon is classified as rare gas as well. Essentially, it is used in manufacture of displays and microchips.

Nowadays, there are not more than 20 units for pure krypton and xenon production (rare gases separation units, URRG) in the world.

Cryogenmash has supplied two of these plants in China — including for Jinan metallurgical complex. In general terms, rare gases are the by-product of air separation into oxygen and nitrogen, which is initially required to metallurgical complexes for improvement of metal quality, decrease in fuel consumption and hazardous emissions, recovery of new types of products, etc. The air-separation plants (ASPs manufactured by Cryogenmash as well) are used for such purpose. After such separation, liquid oxygen contains a small quantity of these gases. Further it is required to process the oxygen at the cryogenic unit; then the produced krypton-xenon concentrate shall be separated into krypton and xenon.
