Inadequate design compensation for pressure piping of liquid air separation plant

Inadequate design compensation for pressure piping of liquid air separation plant
Pressure nitrogen to fine argon tower evaporator pipeline and crude nitrogen condenser liquid air to the upper tower pipeline, this type of pipeline in the design of the compensation amount is not enough to lead to serious tensile deformation of the pipeline, and even weld cracking.

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.

The molecular sieve on the air separation is currently used more 13X-APG type molecular sieve. The process principle is to use the internal porosity of its particles, and has a strong affinity for polar molecules, selective adsorption of carbon dioxide, water, and some hydrocarbons and other impurities. Activated alumina has high compressive strength, low abrasion rate, no pulverization, no bursting, etc. Its resistance to sudden changes in cold and heat is also very strong, and it also has bett...
