Xi'an hands in the carbon dioxide of big chemical fertilizer that big development has completely own intellectual property the first times into China centrifugal compressor. Scientific times report says, this one purpose is finished ended carbon dioxide of Chinese big chemical fertilizer the history that centrifugal compressor and crucial technology count an import for a long time, promoted Chinese fluid mechanical design to make international core competition ability of the technology, broke western country to be opposite the pattern of this technology forestall, for petrifaction industry large equipment is homebred change laid a foundation. Carbon dioxide compressor is the crucial core equipment of unit of large urea production. China go up oneself century since 70 time, introduce  of more than 30 big chemical fertilizer to produce per year from abroad early or late 480 thousand - device of  of 520 thousand tons of urea, use mostly general and electric the compressor of completely centrifugal type that compare grand company newly to produce or depends on its technology production. After 90 time, western country for hold the market, halted the technical output of centrifugal to Chinese carbon dioxide compressor. But because compare the breakdown of the carbon dioxide compressor of grand company newly to stop machine is average nearly 40% what occupy breakdown of unit of whole big fertilizer to stop machine rate, waste the sources of energy not only, and the safe hidden danger with serious existence, make the chronic and stubborn disease that perplexes Chinese petrifaction enterprise. The wide operating mode of large urea plant that Xi'an makes big development is energy-saving model carbon dioxide is centrifugal compressor, assured the energy-saving result when long-term small negative charge runs large urea unit, reduced the manufacturing cost of urea from fountainhead, provided the efficient and a kind of on the safe side, energy-saving, maximum pressure that has own intellectual property for Chinese petrifaction industry medium of little flow chemical industry is centrifugal compressor product and technology. This compressor is in in petrifaction Anqing branch throws industry to move already a year superabundant. According to introducing, its security, stability, energy-saving sex greatly excel international is congener product, make any breakdown had not appeared since using, loss reduces for this company inside a year nearly 4.49 million yuan, and because this product has Chinese own intellectual property, reduce one-time installation cost for this company 31.47 million yuan.
