ABOUT PUTTING INTO OPERATION A NEW AIR SEPARATION PLANT OF OJSC «CRYOGENMASH» ON Dneprovsky metallurgical WORKS

Abstract

On OJSC «Dneprovsky metallurgical works» (Dneprodzerzhynsk, Ukraine) put into operation an air separation plant (ASP) «NitrogenOxygenArgon-40/35-2» (NOAr-40/35-4). It is developed and made by JSC «Cryogenmash» (Balashikha, Russia). Its basic operating mode is reception a 40 thousand m3/h of pure nitrogen and 35 thousand m3/h of gaseous technical oxygen. It also can make the liquid oxygen, nitrogen, argon, krypton-xenon concentrate and neon- helium mixture. In the plant are applied a modern technological circuit and constructive decisions. Pure argon is made in it by a method of low-temperature rectification. A plant is equipped with the automated system of monitoring and control. For its complete set the equipment were made by the known companies as: «Chart» (USA); «Sulzer» (Switzerland); «York» (Canada); «Xomox» (Germany); «Contex-Cryo» and TH «RealSorb» (Russia). The manufacturing products of air separation will allow for combine to increase a release and increase of quality of cast iron and rolled iron. The features and basic parameters of constructed ASP are considered. Its high efficiency and reliability is marked. It is informed about presentation of plant taken place at combine on August, 17, 2007 to which have been invited many experts from the metallurgical, chemical and petrochemical enterprises, factories on manufacture of technical gases. During presentation to have a conversation about  reconstruction on factory-enterprise with full metallurgical cycle, and also about achievements of JSC «Cryogenmash» — the leader of oxygen and cryogenic mechanical engineering.
