Provided are systems and methods for obtaining ethylene and propylene products from, for example, shale gas and shale gas condensate feedstocks. These systems and method operate by utilizing a hydrocracker train to crack C4 and C5 hydrocarbons to a product stream of propane and ethane or using a hydrogenolysis train to process C4 and C5 hydrocarbons to a product stream of propane and ethane that is provided to a cracker for an efficient conversion to ethylene and propylene. The disclosed systems are configured to reduce the amount of offsite hydrogen needed and also provide product streams that include a well-defined set of products as compared to existing approaches.

Shale gas and condensate to chemicals

A process for producing olefins comprising introducing a steam cracker feed to a liquid steam cracker furnace section to produce a steam cracker product comprising olefins, and wherein an amount of olefins in the steam cracker product is greater than in the steam cracker feed; separating the steam cracker product in a separation unit into a hydrogen stream, a methane stream, an olefin gas stream (ethylene and propylene), a saturated gas stream (ethane and propane), a hydrocarbons gas stream (Chydrocarbons), an aromatics stream (Caromatic hydrocarbons), a raffinate stream (Cnon-aromatic hydrocarbons), and a heavies stream (Chydrocarbons); feeding the hydrocarbons gas stream and hydrogen to one or more hydroprocessing reactors to produce a hydrocracking product comprising ethane and propane; and recycling the hydrocracking product and the saturated gas stream to the liquid steam cracker furnace section.

Light olefin production via an integrated steam cracking and hydrocracking process

The disclosure is for a process for producing propylene and hexene (along with ethylene, pentenes, product butenes, heptenes and octenes) by metathesis from butenes (iso-, 1- and cis and trans 2-) and pentenes and then aromatizing the hexenes (along with higher olefins, such as heptenes and octenes) to benzene (along with toluene, xylenes, ethylbenzene and styrene). Since the desired products of the metathesis reaction are propylene and hexene, the feed to the metathesis reaction has a molar ratio for 1-butene:2-butene which favors production of propylene and 3-hexene with the concentration of hexenes and higher olefins in the metathesis product being up to 30 mole %. An isomerization reactor may be used to obtain the desired molar ratio of 1-butene:2-butene for the feed composition into the metathesis reactor. After the metathesis reaction, of hexene and higher olefins are separated for aromatization to benzene and other aromatics.
