Abstract
Systems and methods for producing a decarbonized blue hydrogen gas for cracking operations utilizing a standard separation process, such as Pressure Swing Absorption (PSA), to separate a tail gas mixture of hydrogen and hydrocarbons into hydrogen gas and a PSA effluent that is used in a hydrogen generation unit to produce the decarbonized blue hydrogen gas for cracking operations
Claims20
A system for producing a decarbonized blue hydrogen gas stream for cracking operations, which comprises:
- a cracking furnace comprising a hydrocarbon feedstock and a decarbonized blue hydrogen gas from the decarbonized blue hydrogen gas stream for producing a cracked hydrocarbon feedstock stream and emissions comprising water vapor and residual carbon dioxide;
- a separations train for separating the cracked hydrocarbon feedstock stream into a tail gas stream and a product stream;
- a separation system for separating the tail gas stream into a hydrogen gas stream and an effluent stream;
- and
- a hydrogen generation unit for processing the effluent stream and producing the decarbonized blue hydrogen gas stream and carbon dioxide emissions.
