Carbon dioxide recovery

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

The environmental conditions considered by the air separation plant include: altitude, atmospheric pressure, ambient temperature, air humidity, the content of impurities such as carbon monoxide in the air, etc. These conditions vary with different regions and environments. Different environmental conditions have different effects on the performance of the same air separation plant. 1. Influence of atmospheric pressure on air separation plant: Atmospheric pressure is the pressure exerted on objects in the atmosphere by the gravity of the atmosphere itself. In general, the atmospheric pressure is about 0.1MPa. When the atmospheric pressure decreases, the compression ratio of the air compressor will increase, which will increase the energy consumption of the air separation plant. 2. Influence of ambient temperature and humidity on air separation plant: The increase of ambient temperature will reduce the air compressor's exhaust volume, increase the exhaust temperature, increas
