Description: | The free atmospheric air is sucked in by a multi-stage air compressor through a filter and compressed to the working pressure. After each stage, intermediate coolers and water separators are provided. The compressed air then passes through the (evaporation) pre-cooler and then to the molecular sieve battery where the moisture and carbon dioxide are removed from the process air. It then passes through the exchanger No. 1 where it is cooled by the out-going waste nitrogen and product oxygen. A part of this cold air then flows through an expansion machine and the balance through the 2nd heat exchanger. The ratio of the two air streams is controlled by an expansion valve, RI. Both these streams of air then unite in the lower pressure where it partially liquefies. The liquid air (rich air) then passes through the expansion valve R2 to the upper which is at a lower pressure than the lower . Similarly the liquid nitrogen (poor liquid) travels from the lower to the upper through an expansion valve R3 where the separation of oxygen and nitrogen occurs. Nitrogen being more volatile passes out as a gas from the top of the and this waste nitrogen flows through both the heat exchangers cooling the in-coming air. Similarly product oxygen is also passed through the two heat exchangers to cool the in-coming air and then to the filling manifold via a liquid pump. If a small amount of air is vented out from the upper , higher purity nitrogen can also be obtained from this plant. R4 Valve is provided in order to fasten cooling during start-up. |
