Title: INTEGRATED PROCESS FOR PRODUCING C2+ HYDROCARBONS AND A PROCESS SYSTEM FOR SUCH A PROCESS
Abstract:
The present invention relates to an integrated process for producing C2+ hydrocarbons, preferably C2+ saturated and unsaturated hydrocarbons, comprising a process for oxidative coupling of methane (OCM) which comprises the steps of - producing C2+ hydrocarbons from methane and at least one oxidizing agent, preferably oxygen, and from ethane in at least one OCM reactor comprising at least one OCM catalyst unit and at least one cracking unit; - transferring the OCM effluent from the at least one OCM reactor to at least one fractionation system for separating the C2+ hydrocarbons in one or more hydrocarbon product streams, wherein the fractionation system comprises at least one demethanizer unit (114) for separating methane from C2+ hydrocarbons, at least one C2 splitter unit (121) for separating ethane and ethene, and/or at least one deethanizer unit (118) for separating C2 hydrocarbons from C3+ hydrocarbons, and a propane dehydrogenation process which comprises the steps of - producing propene from propane in at least one dehydrogenation reactor (201); - transferring the dehydrogenation reactor effluent from the at least one dehydrogenation reactor to at least one fractionation system for separating propene from the reactor effluent, wherein the fractionation system comprises at least one deethanizer unit (204) for separating C2 hydrocarbons, from C3+ hydrocarbons, and at least one C3 splitter unit (205) for separating propane and propene, wherein the C3 hydrocarbon effluent from the at least one deethanizer unit (118) in the OCM process is fed into the at least one C3 splitter unit (205) in the propane dehydrogenation process and/or the C2+ hydrocarbon effluent from the at least one demethanizer unit (107) in the OCM process is fed into the at least one deethanizer unit (204) in the propane dehydrogenation process and the C2 hydrocarbon effluent from the at least one deethanizer unit (204) in the propane dehydrogenation process is fed to the at least one C2 splitter unit (121) in the OCM process.
