Liquid oxygen and liquid nitrogen air separation unit

Liquid oxygen and liquid nitrogen air separation unit
Air separation unit is a kind of unit which takes air as raw material, turns air into liquid by compression cycle deep freezing method, and then gradually separates and produces inert gases such as oxygen, nitrogen and argon from liquid air after rectification. Air separation unit is widely used in metallurgy, new coal chemical industry, large-scale nitrogen fertilizer, refining and chemical integration, professional gas supply and other fields. The demand for liquid oxygen and liquid nitrogen air separation unit is also increasing.

Faq of Liquid oxygen and liquid nitrogen air separation unit
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.
