What is the function of the distillation tower in an air separation unit?

  Flow state and heat transfer coefficient Fluid mechanics flow experiments tell us that the fluid flow state can be divided into laminar flow, turbulent flow and excessive flow, laminar flow of each flow beam in an orderly flow, will not interfere with other flow beam. In turbulent flow, the bundles are irregularly intertwined and interfere with each other. Excess flow is a state of flow between laminar and turbulent flow. Of these three flow sta...

Centrifugal compressor is widely used in petrochemical, metallurgy and other industries because of its large exhaust volume, high operating efficiency, simple structure, small area coverage, stable operation and no pulsation of compressed air.

What is the difference between the working principles and applicable scenarios of external compression and internal compression processes in air separation equipment?

Installation of pipes in the cold box in liquid air separation plant Stainless steel welding wire must be baked at the temperature strictly in accordance with the instructions for use and kept warm before use. Receive welding rod, welders must use the electrode insulation cylinder, and do a good job of anti-aluminium welding wire clean, dry and sealed packaging, otherwise chemical cleaning and drying treatment is required before use. Welding rod grades must be used uniformly and not mixed. Pr...

In the air separation unit, the function of air cooling column is to reduce the temperature of air compressed by air compressor. Air cooling column is a kind of hybrid heat exchange equipment. In order to increase the heat transfer area, make the cooling water fully contact with the air and mix completely to enhance the heat transfer effect, the air cooling column usually adopts several structural forms such as packed column, sieve plate column or hollow spray column.

How to adjust the changes in various gas components of the air separation equipment?

  The accumulator is a heat exchanger that transfers hot and cold airflow through a filler as a medium. When the cold airflow passes through the accumulator, the cold is stored in the filler and the airflow is heated, and when the hot airflow passes through the accumulator, the airflow takes the cold from the filler. It has the advantage of being simple in structure, low resistance and not easily blocked. The disadvantages are high switching...
