Air extractor problem (urgent)
Thread Content
Our plant produces methanol from 200,000 tons of coal. Can medium-pressure steam be used in the steam turbine auxiliary equipment extractor (two-stage ejection stage) in the syngas compression position? Generally speaking, low-pressure steam is used! Ask the experts! There is another question. The air extractor used for the air compressor in the air separation station is a low-pressure steam belt. Why do syngas compression jobs require medium-pressure steam energy? (Answer urgently needed)! I beg you on my knees!
Low-pressure steam will cause water in the steam, which will cause an air extractor effect, so it is generally changed to medium-pressure steam.

However, the exhaust system here uses low-pressure steam, which means that the pressure that the exhaust system can withstand is only 1.1-1.2x the low-pressure steam pressure. In this case, do you think medium-pressure steam can be used?
Low-pressure steam is sufficient. Our 250,000-ton steam turbine uses low-pressure steam. Just see if you can achieve the vacuum value required for steam extraction.
If medium-pressure steam is used, generally speaking, low-pressure steam is sufficient. I don’t know which models are suitable for using medium pressure steam (3.55Mpa) to drive the air extractor? (Ask the experts)!
