Dynamics in the Air Separation Industry

Dynamics in the Air Separation Industry
Rotordynamics mainly studies the vibration, balance and stability of the rotor and the support system in the rotating state, especially the lateral vibration of the rotor near and beyond the critical speed.

Small air separation plant KDON (Ar)-6500/6500-180 solution for metallurgical industry
Metallurgical industry can be divided into ferrous metallurgical industry and non-ferrous metallurgical industry. Ferrous metallurgy mainly refers to the production of pig iron, steel and ferroalloy (such as ferrochrome, ferromanganese, etc.), and non-ferrous metallurgy refers to the production of all metals except the former. DEAR air separation has provided a number of complete solutions for the metallurgical industry for many years, accumulated rich experience and helped the efficient development of the metallurgical industry. With years of service experience in the metallurgical industry, the small air separation plant KDON (Ar) - 6500 / 6500-180 cooperated by DEAR air separation and customers provides air separation plant with mature technology, stable equipment working condition, excellent performance and energy saving intelligence, which is highly recognized by customers.
Small air separation plant KDON-6000 / 3200 solution for circular economy industry
Garbage classification, environmental protection and circular economy have been widely advocated in recent years. At present, Chinese lead-acid battery industry and waste battery recycling industry are undergoing profound changes. The integration of the upstream and downstream industry chain of lead-acid battery industry will become the future development trend. KDON-6000 / 3200, a small air separation plant cooperated by DEAR air separation and its customers, is applied in the circular economy industry to practice the green environmental protection, low consumption and high efficiency. Make a contribution to beautify the environment and realize the transformation of garbage into resources. The high-quality air separation plant provided by DEAR air separation has been praised by customers for making contribution to the rise of circular economy.

Braking mode of turbine expander

In general, the liquefaction temperature of nitrogen is higher than that of oxygen, but why can the condensation evaporator between the upper and lower columns of the air separation column use gas nitrogen condensation to release heat to vaporize liquid oxygen? This is because we usually think that the liquefaction temperature of nitrogen is lower than that of oxygen under the same pressure. However, the pressure at the bottom of the upper column of the air separation unit is generally 0.149 MPa, and the pressure at the top of the lower column is about 0.58 MPa. The reason for the different pressure causes the inversion of the saturation temperature of oxygen and nitrogen. It is precisely by using this principle that the condensing evaporator can continuously provide liquid nitrogen for the lower column At the same time, it provides gas oxygen for the upper column as the rising gas to participate in fractionation.
