Vertical axial flow is mainly used for supporting air separation equipment below 10,000 grade (diameter has reached 4.6m), bed thickness 1550 to 2300mm, double-layer single-layer can be arranged, vertical axial flow adsorber airflow distribution is the best. The vertical radial flow adsorber can effectively use the internal space of the container, so that the adsorption…
We are not unfamiliar with all kinds of compressors and steam turbines, but do you really understand their role in the air separation process? An air separation room in a factory. Do you know what it’s like? Air separation, simply put, is a set of industrial equipment used to separate the components of gases in…
The technology of using the different boiling points and relative volatility of components to achieve the separation of different substances has had a preliminary development in the handicraft era, which is the so-called distillation condensation separation technology. In fact, the so-called distillation technology is the special case that there is no distillation section in the…
What is the content of the distillation separation section in the cryogenic air separation textbook? First, liquid-air repeated distillation led to the description of pure oxygen, which belongs to the prehistory of rectification technology, a high technology of the handicraft age, used in the production of luxury goods such as high alcohol and perfume. The…
Distillation technology is the most important technology to achieve mixture separation by using the different boiling points of each component in the mixture. The boiling points of each component are different. When they are in a state of gas-liquid coexistence, the components with low boiling point are relatively volatile, so the relative proportion of the…
After air isothermal compression, liquid air is produced by open heat pump and expansion refrigeration liquefaction process. After air isothermal compression, liquid air can be produced by open heat pump and isothermal enthalpy difference refrigeration liquefaction process. Whether it is expansion mechanism cooling or isothermal enthalpy difference refrigeration, to get liquid air, part of the…
Revised sentence: “Cooling capacity heat is a fundamental concept in cryogenic air separation theory, which although sorted out, remains challenging to comprehend. Therefore, I will elaborate on the concepts of cooling capacity and heat carrier, as they are crucial for understanding the nature of the cryogenic air separation process. Any system that deviates from ambient…
In order to make it easy for everyone to understand, I will make some further explanations. First of all, I will explain the concept of environment, which is a very important concept in thermodynamics. The core concept of the second law of thermodynamics is effective energy, and effective energy is closely related to the environment….
Cryogenic air separation device in addition to the purification product pressure 圊 system, the core part can be divided into two large pieces, one of which is refrigeration, including the compressor heat exchanger and expansion machine, the other is air distillation separation, including the compressor heat exchanger distillation tower. Of course, the refrigeration part and…
The definition of heat is clear and precise, while the concept of cold lacks an accurate definition. Although this does not affect our calculation of the so-called cold balance (which is essentially a heat balance), it is regrettable that the concept of cold should undoubtedly be a corresponding and opposite concept to heat. If it…
For chemical technical personnel with knowledge in chemistry and chemical engineering, the most challenging aspect of learning air separation technology lies in understanding cold capacity, cold capacity balance, and refrigeration. Heat is a fundamental concept in chemical thermodynamics, and heat balance is a crucial knowledge that must be mastered to comprehend thermodynamics. However, the concept…
