Regarding the steam drive and electric drive of air separation turbines
Thread Content
Experts: What are the main differences between steam-driven and electric-driven turbines in air separation units? Thank you
Turbines have advantages such as high individual power output, high efficiency, and long service life; large-scale air separation compressors are basically driven by turbines. In comparison, the design, manufacturing, and operation of large motors are more complex~~
Turbine: Features a smooth and complex starting process, low energy consumption, and is capable of driving high-power mechanical equipment. (The adjustment range is large; fluctuations in steam pressure have little impact.) ) Motor: Fast and simple to start, but high in energy consumption; motors are rarely used to drive equipment worth over 60,000. It also depends on whether there is enough steam on site. (Motor-driven; pressure fluctuations can easily cause it to stop.) Investments are also different.
The question posed by the original poster is a bit off; it should be asked, “What are the main differences between vapor-driven and electrically driven compressors used in air separation?” ” The main difference is that those driven by turbines are called steam-driven, while those driven by electric motors are called electric-driven. Combined with the original poster’s answer, if one owns a thermal power plant and has sufficient steam, then steam drive can be used, as in coal chemical projects ； On the contrary, like a steel mill!
