The metering system in polysilicon plants uses nitrogen??
Thread Content
A few days ago, I heard a Taiwanese businessman say that \"the metering systems in polysilicon plants use nitrogen??\" Instead of ordinary compressed air, because hydrogen is used in the manufacturing process. Is that true?
No, why use nitrogen for the gas in the instruments? Only instrument air is required
Polysilicon plants use compressed air for instruments, while nitrogen serves as an auxiliary gas, used for purging and pressure sealing during startup.
Nitrogen is just a safe gas.
Compressed air is generally used; using N2 not only wastes money but may also create an oxygen-deficient environment
It seems there are no manufacturers that use nitrogen as the gas for instruments; nitrogen is used as a protective gas for safety reasons. Are the people in Taiwan referring to the semiconductor industry?
