The instrumentation pipe for pure argon towers and crude argon liquefiers should be led on the tower closest to the cold box, the lead pipe needs to be upwards. If the outlet of the instrument tube on the cold box plate is lower than the tower outlet and liquid and gas seals have to be made, upward shrinkage of the vessel has to be considered. The protection angle should be reversed to avoid the line being cut by the protection angle when the instrument tube is contracted upwards.

With the continuous development of the petrochemical, fertiliser, coal chemical and metallurgical industries, China has become the country with the largest number of air separation projects and the most active development of air separation technology in the world. However, in recent years, accidents in air separation plants have occurred frequently and alarmingly, resulting in heavy losses of personnel and property. This has led to newer and higher requirements for technology, manufacturing and installation in the air separation industry, which requires constant innovation and the development of new technologies that are constantly applied to the design and manufacture of air separation equipment, thus making great progress in the design and manufacture of large air separation unit .

The classical single column process is the first one to be used in industrial application. However, there are many disadvantages in the classical single column process. One is that oxygen and nitrogen cannot be produced simultaneously, and the other is that the oxygen extraction rate can only reach about 70%. There are two improvement schemes to solve the defects of classical single column process. One is the curren...
