The process of extracting neon and helium from the air separation plant is divided into three steps: the first step is to produce crude neon and helium; the second step is to produce pure neon and helium mixture; the third step is to separate neon and helium, and get pure neon, pure helium products. The purpose of crude neon and helium preparation is to remove nitrogen from raw materials and make them concentrated. Because the boiling points of nitrogen, neon and helium differ greatly, which is over 50 K, it can be separated in the condenser or auxiliary tower by using low pressure liquid nitrogen as cold source, make the nitrogen in the feed gas of neon and helium with the pressure of the lower tower condense, and get the content of neon and helium about 1% ~ 3%, the rest is the mixture of crude neon and helium of nitrogen, and then enter the pure neon and helium preparation process. Some processes of crude neon and helium need to go through hydrogen removal and nitrogen removal. T...

The air pressure test on site is mainly to check the air tightness of the air separation plant. The following problems should be paid attention to during Pressure Test: 1) oxygen is strictly forbidden to be used as the pressure test air source; 2) clean and oil-free pressure test air source should be applied to the oil-free equipment without degreasing after pressure test; 3) the pressure gauge used for pressure test should be checked and sealed before using. Before the pressure test, check carefully whether the pressure gauge valve has been opened; 4) during the pressure test, do not knock the pressure test container with a hammer; 5) during the pressure test, do not dismantle or tighten the screws; 6) when using nitrogen cylinder or air source with higher pressure level to inflate and test pressure to the container with lower pressure, pressure reducing valve should be installed, and direct inflating is strictly prohibited. 7) pressure test after the inflation reaches the specifie...
