Large air separation plant KDON-16000/35000 solution for metallurgical industry
Metallurgical industry is an industry to develop metal mineral resources and produce various kinds of raw materials for metal products. With the progress of science and technology, the metallurgical industry has new requirements for the process, process, management and application research and development of air separation plant. The air separation plant also has the following development trends: first, large-scale and cluster; second, the core technology is gradually localization; third, refinement, which needs to develop high-efficiency energy-saving technology for different application fields; fourth, highly automated and intelligent, reduce manual operation as far as possible, and gradually establish a remote monitoring system by using the rapid development of internet technology to collect in real time according to the operation data of air separation plant, using big data analysis to provide the best suggestions for users, etc. KDON (Ar) - 16000 / 35000, a large scale air separat
Small air separation plant KDON (Ar)-4000/4000-110 solution for metallurgical industry
Metallurgical industry is an industry that exploits metal mineral resources and produces raw materials of various metal products, which is closely related to the national economy and people's livelihood. At present, Chinese iron and steel industry still has the situation of low concentration, insufficient capacity of high-end products and serious surplus of low-end products. 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) - 4000 / 4000-110 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.

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.

The turbine is used as a power source for air compressors in large air separation units, saving a large amount of energy for air separation users, and is a turbine-type mechanical device that converts the thermal energy of steam into mechanical energy. The main steam temperature or pressure has a direct impact on the safety performance of the turbine.In actual operation, as the steam inlet and high pressure parts of the turbine are in direct contact with the high temperature steam, when the stea...
