Integrated process for poly olefin production with reduced greenhouse gas emission

A substantially zero CO2 emissions process for making an amorphous poly alpha olefin (APAO) comprising:

• a. converting alkanes to ethylene, propylene, and 1-butene using renewable electric power in an oxidative-coupling of methane (OCM) plant comprising an ethylene plant, a 2-butene plant, a propylene plant, and a 1-butene plant, the steps comprising:
• (i) providing an ethylene plant comprising an oxidation reactor and a first fractionation train and converting a 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 recover a first 2-butene stream and a second 2-butene stream;
• (iii) providing a propylene plant comprising a metathesis reactor and a third fractionation train and converting a portion of the first 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;
• (iv) providing a 1-butene plant comprising a butene isomerization unit and a fourth fractionation train and converting a portion of the second 2-butene stream in the butene isomerization unit to produce a butene isomerization unit effluent comprising 1-butene and passing the butene isomerization unit effluent to the fourth fractionation train to recover the 1-butene;
• b. polymerizing any one of the 1-butene, propylene, or third ethylene stream in an APAO plant comprising boilers in which boiler stack gasses are produced, the polymerization comprising the simultaneous steps of:
• (i) applying a temperature of 130-175° F. to the 1-butene, the propylene or the third ethylene stream from the 1-butene plant, the propylene plant, or the ethylene plant, respectively;
• (ii) using renewable electric power to power the boilers while scrubbing at least one of the boiler stack gasses with a solvent to sequester carbon dioxide from the at least one of the boiler stack gasses;
• wherein the completion of steps (a.) and (b.) results in substantially zero CO2 emissions into the atmosphere and the formation of an amorphous poly alpha olefin.
