4500/4500-type solution for small and medium-sized air separation plant in nonferrous industry
According to the influence and reform of the general environment of the non-ferrous industry, the problems faced by this industry are becoming more and more serious, and the control of production capacity is particularly important. Recently, the 4500/4500 type small air separation equipment project signed with customers by DEAR Air Separation, through the trial run stage, all the technical indicators have reached or exceeded the design standard, and have been continuously sending nitrogen for several days, which has been well received by users.
Type 13000/22000-350 solution for medium-sized complete air separation plant in chemical industry
In the chemical industry, the demand for air separation plant is stable. The high demand for air separation plant in modern coal chemical industry may drive the demand for large and super-large air separation plant. The 13000/22000-350 type air separation plant produced by DEAR air separation starts smoothly, all indicators reach the monitoring standard and begin to supply gas for customers. Relying on excellent products and high-quality service, DEAR air separation has received high praise from customers.

In the distillation column of air separation, the air is usually pre separated in the lower column, and then distilled into oxygen rich liquid air and pure nitrogen, and then further distillation in the upper column to obtain oxygen and nitrogen products. As a condensing evaporator connecting the upper and lower columns, the pressure nitrogen of the lower column is used to heat the liquid oxygen of the upper column. When the liquid oxygen is evaporated, the gas nitrogen is condensed. The two-stage distillation column can make oxygen and nitrogen products obtain higher extraction rate and higher purity. The working principle of single-stage distillation column is similar to that of the lower column of two-stage distillation column. Oxygen enriched liquid air is at the bottom of the column, and pure nitrogen gas can be obtained at the top of the column. The single-stage distillation column can't separate the air perfectly, so it is seldom used in practice. However, because of its simple

At present, there are two types of common condensing evaporators in domestic air separation units, plate fin condensing evaporator and tubular condensing evaporator. Tubular condensing evaporator is divided into three types: long tube, short tube and coil. The long tube and short tube are all in row. The tube is made of red copper and the tube sheet is made of brass. It is generally used in small and medium-sized air separation plants. Coil type is generally used for auxiliary condensing evaporator. Because there is no fixed liquid level in the coil, the heat transfer coefficient is small, so it has been gradually eliminated. The plate fin condenser evaporator is made of all aluminum structure, and the plate unit is arranged in vertical star shape. Its characteristics are compact structure, light weight, small volume and easy to manufacture. It is widely used in large and medium air separation plants. Due to the gradual enlargement of the air separation unit, the heat excha
