Air separation unit maintenance procedures

Air separation unit maintenance procedures
Air separation unit maintenance procedures need to determine the maintenance cycle and content, maintenance quality standards, commissioning and acceptance maintenance and troubleshooting. Before the maintenance, the staff should prepare the air separation unit maintenance procedures according to the regulations, so as to avoid missing items and causing unnecessary economic losses.

With the development trend of large-scale air separation plant, the column support of its matching cold box equipment tends to be large-scale. The traditional support structure has complex structure and poor bearing capacity. Through the use of finite element analysis software, DEAR air separation carries out finite element analysis and optimization on the commonly used experienced column of air separation plant, so as to improve the bearing capacity of support and reduce the processing difficulty, to reach the purpose of saving material cost.

Under the design working condition, the positive and return air volume of the Heat section of the switching heat exchanger (or cooler) is basically equal. While in the cold section, the return flow volume must be larger than the positive flow air volume, and keep a certain proportion relationship, so that the temperature difference of the cold end is within the required range of moisture and carbon dioxide self-elimination, and the temperature difference of the hot end should be appropriate. In actual operation, when the temperature condition fluctuates, the method of changing the air volume or the distribution of product gas volume is also often used to adjust. When the middle temperature deviation occurs between two groups of switching heat exchanger (or between two groups of refrigerators), air inlet stop valve (or thin film butterfly valve) can be used for adjustment. The group with lower temperature in the middle part is larger, increasing air ventilation. In this way, the requ...
