KZO-20 type oxygen generator is the smallest skid-mounted cryogenic oxygen generation plant which produce 20Nm3 high purity O2 per hour(The purity of O2 is more than 99.6% which meets both the medical use standard and the industry use.).
General performance of KZO-20 oxygen plant is as following:
Model | Product | Flow rate | Purity | Power consumption | Water consumption |
KZO-20 | O2 | 20Nm3/h | ≥99.6% | 59KW/h | 0T |
Air compressor The inlet air will be compressed into the pressure as per process required. It is sprayed-oil screw compressor, box-body construction, it have low noise, whole machine gather gas, lubricate, water, electric, cooling and instrument to one, realize machine and electric become one body. | Pre-cooling unit The outlet temperature of compressed air is around 40ºC which is too high for the down-stream molecular sieves high efficiency operation, in order to increase the performance of the molecular sieves, a pre-cooling unit is required. | Purifier Remaining contaminants in the process air such as moisture, carbon dioxide, acetylene (and etc.) shall be removed before enters into the main heat exchanger, a molecular sieves system is adopted. |
Turbine expander Turbine expander also referred to as a turbo-expander, is a centrifugal or axial-flow turbine, through which a high-pressure gas is expanded to produce work. It's the one of core part of the whole plant. | Fractionating column It adopt fin type heat exchange, made in aluminum, heighten heat exchange affection, depress the operating pressure, reduce the power consumption furthest, saving cost. | Liquid pump Liquid oxygen pump is a kind of cryogenic liquid pump, by which the pressure of oxygen can be increased to achieve the purpose of transporting oxygen. |
