Abstract
Processes and systems that utilize a fuel cell for carbon capture from a petrochemical stream that contains hydrogen and methane. The petrochemical stream can be the tail gas of a hydrocarbon cracking system, or any other petrochemical stream containing hydrogen and methane. The petrochemical stream can be separated into a hydrogen product stream and a methane product stream, before sending the methane product stream to the fuel cell. The fuel cell converts methane to carbon dioxide and hydrogen to water, while generating electricity that can be used to power equipment.
