Technical Features
1 A novel specialized adsorbent exhibits high separation selectivity for olefins, alkanes, nitrogen, and other gases, resulting in high purity and yield of the recovered olefin and alkane products.
2 As pioneers in applying pressure swing adsorption units to this field, we have not only overcome numerous challenges but also accumulated valuable experience, thereby establishing our competitive edge. Following appraisal by the Urumqi Municipal Science and Technology Commission and acceptance of the pilot-scale unit at Daqing Petrochemical by China National Petroleum Corporation, this technology has been recognized as being at an internationally leading level.
3 1. Utilizing the principle of pressure swing adsorption, the unit operates at ambient temperature, featuring low energy consumption, a high degree of automation, and a simple process flow.
