What are the driving forms and characteristics of the compressor of the air separation plant
Nov 19, 2025
Author: DEAR AST

The compressor of the air separation plant has two driving modes and their respective characteristics are as follows:

1. Turbine drive:

Steam turbine is widely used in electric power, chemical industry, metallurgy and other industries and fields because of its characteristics of high speed rotation, stable operation, small wear and long continuous operation time. However, the one-time investment of steam turbine drive is relatively large, and the requirements for heating pipeline and production system are relatively high, the equipment production cycle is long, the installation and commissioning as well as the startup and shutdown process of the whole system are relatively complex, and the boiler discharge also has certain pollution to the environment. Generally, large air separation equipment is driven by steam turbine.

2. Motor drive:

Motor is an indispensable rotating drive equipment in the industrial production process. The motor covers all production links in the industrial industry with the advantages of stable operation, simple start and stop control, and short production cycle. And the motor installation is relatively independent, which can better ensure the construction period. However, high-power motors require high power grid conditions when starting, which is easy to affect the surrounding equipment. 35000 m at present ³/ The air separation equipment below grade h is mostly driven by motor.

Special pressure-bearing equipment generally bears internal pressure, that will cause tensile stress inside the shell, which is called working stress. The working stress is directly proportional to the pressure and diameter, and inversely proportional to the vessel wall thickness. The axial stress is half of the circumferential stress. Therefore, for cylindrical vessels, the stress of longitudinal weld is twice that of girth weld. Because the geometric shape of the spherical shell is symmetrical to the spherical center, and the axial stress is equal to the circumferential stress in numerical value. Therefore, the wall thickness of the spherical vessel can be reduced by half as much as that of the cylindrical vessel under the same pressure and diameter.
