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 plant is a low temperature liquid and its temperature rise is accompanied by phase change heat, so its cold energy is divided into sensible heat and lat...

There are 10 ways to transilluminate the welding seam of air separation unit, which are suitable for different occasions. Single wall is the most commonly used transilluminating method, but when the radiation source or film cannot enter the inside small diameter vessel and pipeline, double wall transilluminating method is adopted. The selection of transillumination method should consider all factors synthetically. For example, according to the principle of selecting the transillumination method which is beneficial and improves the sensitivity, single wall transillumination should be selected as far as possible. According to the principle which is conducive to the detection of corresponding defects, the outside radiation source is preferred for the detection of cracks on the inner wall of the container.

In the condensation evaporator the liquid oxygen is heated to evaporate and the gas nitrogen is cooled and condensed. Both the liquid oxygen and the gas nitrogen are in a saturated state. If the saturation temperature of nitrogen is lower than the saturation temperature of oxygen at the same pressure, the purpose of condensing gas and nitrogen with liquid oxygen cannot be achieved. For this reason the heat transfer temperature difference in the condensing evaporator must be established by the pr...
