Direct oxidation of ethylene to produce ethylene oxide. Carbon dioxide analysis is an important quality control indicator for ethylene glycol. The level of carbon dioxide content has a significant impact on the process operation and equipment operation of downstream production facilities.
Carbon dioxide is a strictly controlled indicator in industrial ethylene oxide.
The micro cell thermal conductivity detector used in the national standard is not yet widely adopted and its use is limited;
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a portable methane conversion furnace gas chromatography method for the determination of carbon dioxide in ethylene oxide. The method uses a blowback system for detection, and a large amount of ethylene oxide does not enter the nickel catalyst conversion furnace, which not only protects the catalyst but also shortens the analysis time. The improved method has been proven to be feasible through repeated and accurate experiments.
Name: Methane Converter
Filler: Nickel Catalyst
Specification: HH-790CH4-GC
Application: Trace carbon monoxide, carbon dioxide converted to methane
characteristic;
No need to modify the instrument, direct docking, saving time and effort, realizing interconnection and intercommunication of instruments of different specifications and models
Equipped with an injection device, chromatographic column system, temperature control system, and optional central cutting technology to protect the catalyst and extend its service life.
