Abstract
The present invention relates to a method for recovering light olefins, which can achieve an increase in propylene production and a reduction in the basic unit of a process by feeding steam into five serially connected dehydrogenation reactors, and can diversify the product of a propane dehydrogenation reaction process from a propylene single product into propylene and ethylene by separately collecting ethane and ethylene, i.e., by-products of the propylene production process, and converting the ethane into ethylene, thereby improving the economic efficiency of the process and selectivity.
