Process for co-producing commercially valuable products from byproducts of heavy oil and bitumen upgrading process
First Claim
Patent Images
1. A process for co-producing commercially valuable products from by-products of a process for upgrading or refining heavy oil or bitumen to formulate synthesized hydrocarbons, comprising:
- (a) forming a non-distilled bottom fraction from a source of heavy oil or bitumen feedstock;
(b) feeding said bottom fraction to a syngas generating circuit for formulating a hydrogen lean syngas stream via a non-catalytic partial oxidation reaction;
(c) providing a first hydrogen rich syngas stream from a syngas generator;
(d) subjecting a portion of said first hydrogen rich syngas stream to a hydrogen separator unit to provide a purified hydrogen by-product stream and a second hydrogen rich syngas stream;
(e) subjecting at least a portion of said hydrogen lean syngas stream, said first hydrogen rich syngas stream, said second hydrogen rich syngas stream or a combination thereof, to a carbon dioxide removal operation to obtain a purified hydrogen rich syngas stream an a carbon dioxide by-product stream;
(f) reacting said purified hydrogen rich syngas stream in a Fischer-Tropsch reactor to formulate synthesized hydrocarbons; and
(g) converting said purified hydrogen by-product stream and/or said carbon dioxide by-product stream into said commercially valuable co-products.

Abstract
The present invention is directed to modifications of bitumen and heavy oil upgrading and refining processes to synthesize synthetic crude oil and other valuable synthesized hydrocarbon products in an efficient manner along with the production of commercially valuable co-products from by-products formed by the upgrading process.
