GTU - 8 PDF Печать

GTU - 8 forms part of nitric acid producing unit UKL-7 as a source of compressed air. GTU is designed to supply compressed air for the process of non-concentrated nitric acid production and for recuperation of tail gas pressure and heat energy. Chemical industrial enterprises are among the main users of GTU as part of UKL-7.
