Effective energy analysis of cold energy utilisation in liquid air separation plants

Effective energy analysis of cold energy utilisation in liquid air separation plants
Jul 18, 2024
Author: DEAR AST

Effective energy analysis is an important analytical method for energy systems. Liquid air separation plant is a low-temperature liquid mixture with methane as the main component, including nitrogen, ethane, propane and other components, which has a large temperature difference and pressure with the outside world. Liquid air separation plants's temperature accompanied by phase change heat, so its cold energy is divided into sensible heat and latent heat. The effective energy analysis shows that when the pressure is certain, the ambient temperature difference increases and the effective energy of the liquid air separation plant cold increases, when the temperature is certain, as the pressure of the liquid air separation plant increases, the effective energy of the pressure increases, but the effective energy of the low temperature decreases. One of the reasons for this is that as the pressure increases, the bubble point of the liquid mixture rises and the temperature difference between it and the environment decreases, and as the pressure increases, the latent heat of vaporisation of the liquid mixture nears the critical zone decreases.

Dear Air Separation relies on a technical team formed by universities and research institutes to design reasonable and efficient liquid air separation plants, small air separation units and large air separation units.

1. Before filling with pearlite, the water accumulated on the foundation surface of air separation unit must be removed, dried with hot air, and all manholes shall be closed. 2. When filling pearlite, all containers and pipes in the cold box should be inflated and kept at 50kPa pressure, then slightly open the valve of each meter pipeline, and all thermometers should be electrified to check whether the thermometer cable is damaged during the filling process. 3. The filled pearlite shall not be mixed with combustibles. 4. When filling with pearlite, coarse mesh or pearlite pouring device should be set at the manhole on the top of the cold box to prevent whole bag pearlite from entering the cold box. 5. After the pearlite is filled, the manhole shall be sealed.
