Method and Apparatus for Managing Hydrogen Content Through The Conversion of Hydrocarbons Into Olefins

摘要

An apparatus and method are provided for processing hydrocarbon feeds. The method enhances the conversion of hydrocarbon feeds into conversion products, such as ethylene and propylene. In particular, the present techniques combine a first hydrocarbon feed with a second hydrocarbon feed and a hydrogen (H2) containing stream to manage the hydrogen content of the feed provided to a pyrolysis reactor. The mixture is then exposed to high-severity operating conditions in a pyrolysis reactor and further processing into desired olefins.

1. A hydrocarbon conversion method comprising:
a) providing a weight based rate (WT1) of a first hydrocarbon feed having a carbon parameter (CHC1) and a hydrogen parameter (HHC1), where the hydrogen parameter (HHC1) is <14.0 wt % of the first hydrocarbon feed; b) providing a weight based rate (WT2) of a second hydrocarbon feed having a carbon parameter (CHC2) and a hydrogen parameter (HHC2), where the hydrogen parameter is ≧14.0 wt % of the second hydrocarbon feed; c) providing a weight based rate (WTD) of a hydrogen (H2) containing stream having a hydrogen gas content (HH2D) and a hydrocarbon content (HCD), wherein the hydrocarbon content (HCD) has a hydrocarbon hydrogen parameter (HHCD) and a hydrocarbon carbon parameter (CHCD) as a weight percent of total hydrogen (H2) containing stream; d) combining the first hydrocarbon feed and second hydrocarbon feed and the hydrogen (H2) containing stream to form a pyrolysis feed having (i) a hydrogen parameter (HHCT) in the range of 12.0 wt % to 18.0 wt % based on the weight of the pyrolysis feed and (ii) a total atomic hydrogen to carbon ratio (HCRT) in the range of 3.0 to 15.0; and e) exposing the pyrolysis feed to a peak pyrolysis gas temperature ≧1400.0° C. to produce a reactor product comprising ethylene and acetylene.
