Abstract : The All-Union Scientific-Research Institute for Oxygen Equipment developed a VNIIKIMASh type BR-6 machine designed to produce 15,000 cubic m per hour of nitrogen with a 0.002% content of 02; 7840 cubic m per hour of low-purity oxygen with 95% 02; and 160 cubic m per hour of high-purity oxygen with a 99.5% concentration of 02. The new BR-6 plants have been providing adequate supplies of pure nitrogen and technical oxygen to synthetic ammonium other chemical plants. The BR-6 plant consists of several air turbocompressors an air-fractioning unit, turboexpanders, a controlling and measuring instrument panel, switching mechanism, preheaters, and other equipment. Unlike the G-6800 machine operating at two pressure levels, the BR-6 nitrogen-oxygen plant is designed for a low pressure level, a system used earlier only in technical oxygen plants. The low-pressure system makes it possible to eliminate reciprocating engines, chemical air purifiers for removing carbon dioxide from the air, an ammonium refrigeration unit, and reversible heat exchangers for freezing out the moisture thus resulting in a highly efficient unit.
