Alkane dehydrogenation technology is a new comprehensive utilization technology of light alkanes (such as propane, isobutane, etc.) developed by our company. The technology has successively passed the industrial application of 50000 T / a isobutane dehydrogenation unit, completed and put into operation 150000 T / a isobutane dehydrogenation industrial unit, and a set of 80000 T / a isobutane dehydrogenation unit is under construction. The picture shows the industrial application experimental device of 50 kt / a isobutane dehydrogenation in Zhongjia Huachen.
