What is meant by the phenomenon of "gas plugging" and "cavitation" in centrifugal liquid oxygen pumps for DEAR Liquid air separation unit and what are the hazards?

The upsizing of air separation plant has became an inevitable trend of the development of national economy. A few years ago, the domestic air separation industry had achieved the air separation performance of 100000 m³/h level, and there were more than 150000 m³/h air separation plant abroad. With the gradual increase of the scale of air separation plant, its energy consumption is also increasing. In order to save energy, reduce consumption and reduce pollution, it is of great significance to study the driving mode of compressor for large-scale air separation plants. 1. Turbine drive: Steam turbine is widely used in electric power, chemical industry, metallurgy and other industries and fields because of its axisymmetric high-speed rotation characteristics, smooth operation, small wear and long continuous operation time. However, the one-time investment of steam turbine drive is relatively large, and the requirements for heat supply pipeline and production system are high. The pla

Why do the design, installation, and production of complete sets of air separation equipment require various parameters from the demand side?
