Abstract
A substantially zero carbon emission process for making amorphous poly alpha olefins including, converting alkanes to olefin monomers ethylene, propylene, and 1-butene or combinations thereof using renewable electric power in an oxidative-coupling of methane plant including the steps of passing alkanes through an ethylene plant while adding oxygen, passing the first polymerization grade ethylene through a 2-butene plant, passing a first of the two 2-butene streams and one of the polymerization grade ethylene through a propylene plant, and passing a second of the two 2-butene streams through a 1-butene plant. The next step in the process for making amorphous poly alpha olefins includes polymerizing at least one of the polymerization grade alkenes which includes applying a temperature of 130 degrees Fahrenheit to 175 degrees Fahrenheit to at least one of the polymerization grade alkenes and scrubbing at least one boiler stack gases.
