1. A method comprising:
heating and reacting a petroleum residue stream with an oxygen stream and a carbon dioxide stream in a gasification unit to produce a syngas stream comprising carbon dioxide, carbon monoxide, and hydrogen;
converting at least a portion of the carbon monoxide of the syngas stream into carbon dioxide to produce a shifted syngas stream;
separating at least a portion of the shifted syngas stream to produce a syngas feed stream, wherein separating at least the portion of the shifted syngas stream comprises:
separating at least a portion of carbon dioxide from the shifted syngas stream to produce a recycle carbon dioxide stream; and
separating at least a portion of carbon monoxide from the shifted syngas stream to produce a carbon monoxide stream;
converting at least a portion of the syngas feed stream into methanol to produce a methanol stream;
converting at least a first portion of the methanol stream into one or more alkenes to produce an olefins stream;
reacting at least a second portion of the methanol stream with at least a portion of the carbon monoxide stream to produce acetic acid; and
recycling at least a portion of the recycle carbon dioxide stream to the gasification unit to facilitate the production of the syngas stream.
