Comparative analysis of H/O cycle power plants based on different hydrogen production systems from fossil fuels

Energy integration of acetylene and power polygeneration by flowrate-exergy diagram

“…4, the H 2 /O 2 cycle based power system consists of the following subsystems: (i) steam reforming of methane (SRM) reaction subsystem, which includes a prereformer, a heat exchanger and a reformer [15]; (ii) water gas shift (WGS) subsystem including a WGS converter and a hydrogen separator; (iii) H 2 /O 2 cycle subsystem including compressor, combustor, steam turbines and heat exchangers [20][21][22].…”

Model-Centered Approach to Early Planning and Design of an Eco-Industrial Park around an Oil Refinery

“…Given its lower carbon content of 0.2 kg CO 2/kW h thermal (vs 0.33 kg CO2/kW h thermal for coal), it is probably wise to save it for applications where CCS is unlikely. There exist various technologies for a CHP with CCS (31)(32)(33)(34), and a precombustion solution would offer more heat surplus for the refinery and flexibility with respect to the utilization of the hydrogen produced in the process. The gas turbine technology, however, has not yet been verified for hydrogen, given the high temperature of the combustion (32).…”

A proposal for a novel multi-functional energy system for the production of hydrogen and power

“…Nevertheless, both the natural gas-based and the coal-based polygeneration systems have their advantages and disadvantages [7][8][9][10]. First, in the case of a natural gas-based polygeneration system, the reforming reaction happens in a reformer with a simpler configuration and lower capital cost.…”
