Abstract
A process for reducing carbon dioxide emissions from a reforming process is provided. This method includes producing a hot crude syngas stream in a reformer; indirectly exchanging heat between the hot crude syngas stream and a process stream, thereby generating a cool crude syngas stream; and introducing the cool crude syngas stream into a first separation means, thereby producing a syngas stream and a fuel hydrogen stream. The present invention also includes introducing the syngas stream into a second separation means, thereby producing a product syngas stream, and a carbon dioxide rich stream; blending the fuel hydrogen stream with a hydrocarbon stream, thereby producing a blended fuel stream; and introducing the blended fuel stream into a reformer, thereby generating an exhaust stream that has a lower percentage of carbon dioxide than it would without the introduction of the fuel hydrogen stream.
