Product By Integrated Process for Producing Propylene Polymers and Copolymers with Reduced Greenhouse Gas Emission

A product comprising isotactic polypropylene homopolymers or copolymers produced by a substantially zero carbon dioxide emissions process comprising:

• a. converting alkanes to ethylene, propylene, and butene using renewable electric power in an oxidative-coupling of methane (OCM) plant comprising an ethylene plant, a 2-butene plant, and a propylene plant, comprising:
• i. providing an ethylene plant comprising an oxidation reactor and a first fractionation train and converting natural gas and oxygen in the oxidation reactor to produce an oxidation reactor effluent comprising ethylene and passing the oxidation reactor effluent to the first fractionation train to recover a first ethylene stream, a second ethylene stream, and a third ethylene stream;
• ii. providing a 2-butene plant comprising a dimerization unit and a second fractionation train and converting a portion of the first ethylene stream in the dimerization unit to produce a dimerization unit effluent comprising 2-butene and passing the dimerization unit effluent to the second fractionation train to produce a 2-butene stream;
• iii. providing a propylene plant comprising a metathesis reactor and a third fractionation train and converting the 2-butene stream and a portion of the second ethylene stream in the metathesis reactor to produce a metathesis reactor effluent comprising propylene and passing the metathesis reactor effluent to the third fractionation train to recover the propylene;
• and
• b. polymerizing the propylene and, optionally, the ethylene in a polypropylene plant while applying a propylene polymerization technology, using renewable electric power, and scrubbing carbon dioxide from any fired heater or boiler stack gasses, thereby emitting substantially zero carbon dioxide atmospheric emissions.
