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

A user of DEAR air separation reflected that when the air separation plant was put into operation, a large liquid nitrogen storage tank was equipped for emergency backup when the air separation was stopped or export of liquid products. The value of oxygen content in nitrogen product is designed to be less than 3ppm (i.e., < 3 ×10-6) due to the high requirement of users for nitrogen purity. But in fact, the oxygen content of liquid nitrogen in the tanks had been found more than 5ppm. The substandard purity of liquid nitrogen not only affects the export of products, but also directly affects the emergency backup of liquid nitrogen backup system.
