Sixth, hydrogen and nitrogen mixed gas application

Overview In the electronic device production process, various high purity gases are widely used. According to the different uses of high purity gas in the process, it can be divided into protective gas, reaction gas and carrier gas. Used as a shielding gas are hydrogen, nitrogen, argon and a mixture thereof. In China, in order to obtain hydrogen and nitrogen, the general manufacturer has a hydrogen oxygen station and a nitrogen oxygen station. In order to obtain higher purity hydrogen, the hydrogen and oxygen stations are generally prepared by electrolytic pure water. This method requires a large amount of electric energy to electrolyze water, generally reaching 4.5 to 5.5 kWh/Nm to 3H_2, resulting in high cost. In order to reduce power consumption and reduce costs, various mixed gases are being developed and applied at home and abroad. Among them, the application of nitrogen-hydrogen mixed gas is the most. In foreign countries, liquid hydrogen and liquid nitrogen vaporization methods are used to obtain nitrogen-hydrogen mixed gas, and liquid ammonia decomposition method is also used to obtain nitrogen-hydrogen mixed gas.
