Gas throttling

Gas throttling
Sep 06, 2021
Author: DEAR AST

The most basic feature of gas throttling is that the enthalpy before and after throttling remains unchanged, while the volume after throttling increases, and the molecular potential energy always increases. Therefore, the change of molecular kinetic energy, that is, the change of temperature, depends on the relationship between the decrease of flow kinetic energy and the increase of molecular potential energy. When the decrease of flow kinetic energy is equal to the increase of molecular potential energy, the molecular kinetic energy and temperature remain unchanged after gas throttling. This temperature is called the conversion temperature. When the gas temperature before throttling is less than this temperature, the temperature after throttling decreases. When the gas temperature before throttling is greater than this temperature, the gas temperature after throttling increases.

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
