In the air separation plant, the adsorption capacity of the adsorbents is expressed by static adsorption capacity and dynamic adsorption capacity. The...
The main causes are as follows: 1. The structure is unreasonable, the welding seam is concentrated and the welding joint stress is too large. 2. Whe...
Before starting, the following preparations should be done first: 1) Check whether the unit has the starting conditions (including the reason of last ...
More than half of all air separation equipment accidents were the explosion caused by the main cooling system. When processing air, all the impurities...
There are mainly the following factors that affect the output of oxygen: 1) insufficient processing air volume. The reasons for the shortage of air vo...
The most likely leakage of switching heat exchanger is the welding line, especially the joint of the head and the pipeline. Most of the causes of leak...
For the pipeline with pressure, the easiest problem in the production process is the leakage at the connection flange. Once leakage is found, do not t...
The amount of expansion air entering the upper column increases, and the reflux ratio of the rectification section decreases correspondingly. In order...
The air contains 0.932% argon. When 99.6% oxygen is to be produced from the upper tower, 1.05% argon must be contained in the nitrogen discharge. From...
On the one hand, the expansion heat exchanger is to reduce the temperature of the air after expansion by utilizing the cooling amount of the sewage ni...
Small air separation equipment consists of air compressor, purifier, air separation Tower, expander, oxygen compressor and other main parts. Before st...
In order to reduce the installation cost of the equipment, more and more air separation users require the cold box to be assembled when delivered from...
