| Abstract: | In 48000 m^3/h air separation plant,the energy-saving type steam heater used for heating the molecular sieve-regenerated gas leaks due to moisture freezing and expansion. After fixing liquid drain pipe,its anti-freezing and liquid drain performances are greatly improved to ensure well run under extremely cold weather in northern region. Here,the main technical parameters and structure steam heater are briefed,and the specific technical reform scheme is described. |
