Shanghai new molecular sieve Ltd. - sieve sieve is then cut to a # furnace programmed pause position, and rushed to the scene to pick up big F wrench, manual valves fully open valve # 2 furnace and export before the furnace cut to 2 # Work sieve, sieve programmed resume normal work after opening, to ensure the normal production of ASU. After maintenance personnel within the Department confirmed three electric heaters electric tube, a group of electric heating pipe insulation is damaged it can not work cause breakdown, natural heating process temperature to reach the setpoint range Dingzhou sieve, heating temperature is not enough, the molecular sieve regeneration is not complete, it will work with the water into the cold box when Zhuozhou zeolite molecular sieve, which is a direct consequence of an air separation unit can cause unplanned shutdowns. The Hui are "ripped a mystery" is to keep the company's stable production. Domestic and hydrogen, oxygen, nitrogen, some classical methods commonly used by gas chromatography, basically with molecular sieve column and argon carrier gas. A trial period in its purity oxygen-hydrogen analysis, they found that this method has some drawbacks. Its performance is: good initially activated molecular sieve effect, hydrogen peak, peak oxygen away near; molecular sieve column after a period of Qian'an molecular sieve oxygen peak tailing; hydrogen peak soon completely covered peaks of oxygen, causing no critical analysis of oxygen content. When the company resolved to argon carrier gas oxygen content measured hydrogen, nitrogen, hydrogen content and purity, resulting in hydrogen cover peak oxygen peak shortly after the problem with the molecular sieve column, and then solve the over with helium as the carrier gas when analyzing costs high. Muan new zeolite molecular sieve _ (certified) _ new zeolite molecular sieves by Shanghai Limited. Shanghai new molecular sieve Limited (www.molsionms.com) is Shanghai's Songjiang District, elemental leaders, over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. There are new leaders in the molecular sieve with the staff warmly welcome all inquiries negotiations to create new molecular sieve a better future.
