What safety problems should be paid attention to when contacting nitrogen

Nitrogen is a colorless, tasteless and odorless inert gas. It is harmless to human body, but when the nitrogen content in the air increases, it reduces the oxygen content, making it difficult to breathe. If pure nitrogen is inhaled, it will be asphyxiated due to severe hypoxia and cause death.

In order to avoid the increase of nitrogen content in the air in the workshop, nitrogen separated from the air separation plant shall not be discharged indoors. When there is a large amount of nitrogen, you should wear an oxygen respirator. When overhauling nitrogen charging equipment, vessels and pipelines, air shall be used to replace them, and the operation shall be allowed only after the oxygen content is qualified. During maintenance, the nitrogen valve shall be supervised to prevent personal accidents caused by opening the valve by mistake.

The research rooted in and practiced in the field of air separation is a professional research and development, manufacturing, installation of various complete sets of air separation equipment, focusing on the pressure and challenges faced by customers, and is good at providing customers with the most competitive air separation project design scheme. DEAR gas mainly produces conventional gases such as oxygen, nitrogen, argon, carbon dioxide, etc. Provide users with timely and accurate technical support, find possible problems as early as possible, and handle them in a timely manner.

Another part of the nitrogen vaporized in the liquefier is heated up to a certain temperature in the high pressure heat exchanger and pumped out to the low pressure nitrogen press, the nitrogen separated by the gas-liquid separator is also heated up by the high pressure heat exchanger and then goes to the low pressure nitrogen press, compressed to a certain pressure by the low pressure nitrogen press and then back to the high pressure heat exchanger for heat exchange with liquid air separat...

Special pressure-bearing equipment generally bears internal pressure, that will cause tensile stress inside the shell, which is called working stress. The working stress is directly proportional to the pressure and diameter, and inversely proportional to the vessel wall thickness. The axial stress is half of the circumferential stress. Therefore, for cylindrical vessels, the stress of longitudinal weld is twice that of girth weld. Because the geometric shape of the spherical shell is symmetrical to the spherical center, and the axial stress is equal to the circumferential stress in numerical value. Therefore, the wall thickness of the spherical vessel can be reduced by half as much as that of the cylindrical vessel under the same pressure and diameter.
