Compressed air purification equipment

In the air separation plant, the main heat exchanger is the key equipment to ensure the performance of the whole set of equipment. The function of the main heat exchanger in the molecular sieve pre purification process air separation equipment is to ensure the temperature difference at the hot end to be kept at the design value by recovering the cold quantity of the backflow gas, provide sufficient expander gas to expander, make up for the cold quantity loss of the equipment, and provide the raw gas under the design condition for the lower tower.

Since the first set of high-purity nitrogen air separation equipment was developed and produced in 1978 in China's air separation market, the demand of domestic nitrogen market is growing due to economic development . The research and development and manufacturing of nitrogen production equipment have made a leap forward development in recent decades, and the production technology of high-purity nitrogen equipment has become increasingly mature and has fully realized localization.
