Kind Code:
A1
Abstract:
The present invention relates to a fractionating column and an application thereof. The fractionating column comprises a housing and a partition provided in the housing; the partition partitions the interior of the housing into a lower section A (flash evaporation section) and an upper section B (fractionation section). The fractionating column of the present invention has a compact structure, cracking gas is separately fed to a liquid furnace and a gas furnace, and a flash evaporation method is used to lower the viscosity, thereby reducing device investment and space occupied and improving heat utilization, providing great significance for long-term stable operation of ethylene plants as well as energy conservation and consumption reduction.
