“…Zhou et al [31] presents a systematic modeling methodology for the optimal synthesis of sustainable refinery hydrogen networks accounting for both the economic and the environmental aspect. Deng et al [32,33] proposed two different superstructure-based mathematical programming models to synthesize the hydrogen network. One model can be applied to optimize the hydrogen network with the hydrogen intermediate header; the other can be applied to make a comparative analysis of several scenarios with the hydrogen utility, compressor, purifier and all the feasible interconnections considered.…”

Analysis of the Relation between Coupled Sink and Purification Based on Hydrogen Network Integration

In a hydrogen network, sinks and sources are generally connected to reactors or purifiers, which affect their compositions and flow rates. The relationship between these streams is studied based on the integration of the hydrogen network to identify the feasible and optimal operating conditions of reactors and purifiers. Equations are deduced to describe the quantitative relationship between hydrogen consumption, hydrogen concentration, flow rates of coupled sink and source, purification feed, and purified product. The purification and hydrogen‐consuming reactor parameters can be optimized in the design and operation stage of a hydrogen network. The case study proves that the proposed method is simple, easy to understand, and can be applied to identify the variation trend line and feasible region accurately without tedious calculation.

“…by means of a steam CLR process. Half of the hydrogen produced worldwide is used for ammonia production [16], and a quarter is used for hydrotreating and hydrocracking in refineries [16][17][18]. The CLR process presents a significant advantage for the NH 3 production industry, since it is possible to obtain syngas/H 2 and pure N 2 simultaneously under autothermal conditions [8].…”

Chemical looping reforming (CLR) is a process that enables the production of syngas/H 2 with CO 2 capture by using oxygen carriers that prevent direct contact between the fuel and air. This work presents the experimental results obtained in a 1 kW th CLR unit using a Ni-based oxygen carrier and diesel as fuel, as a first trial for further advancement with heavier liquid fuels. The influence of the main operating conditions, such as oxygen-to-diesel molar ratio and the H 2 O and/or CO 2 feed into the system, was analysed in both steam and dry CLR processes. In addition, the combined steam-dry CLR process enabled the production of syngas with any H 2 /CO molar ratio between 0.2 and 3, which resulted in a wide variety of final products during its use in Fischer-Tropsch processes. In all cases, the syngas composition was close to that given by the thermodynamic equilibrium. These results demonstrate the technical feasibility of steam, dry, and combined steam-dry reforming processes for liquid fossil fuels in a chemical looping system.
