26000 internal-compression oxygen generating ASU start up successfully one-time The oxygen plant have the following features. Adopting modularizationdelivery, each system is skid into modules, all piping of fractional column is completed, just need to connect on job site. With round cold box structure, better wind-resistance ability. High oxygen recovery rate. Low power consumption of products, lowest power consumption among kin running liquid oxygen plants. Short start-uptime of liquid oxygen plant, after first time successful commissioning, only 30 hours are needed for plant to output qualified products.
