“…The PSA system provides a hydrogenrich fuel that is used to generate electricity in a combined cycle. The CLC system oxidises the residual CO and methane in the flue gas stream to produce a CO 2 stream that can be sequestered and a gas stream that can be delivered to the combined cycle to generate electricity [132].…”

Currently, hydrogen energy is the most promising energy vector, while gasification is one of the major routes for its production. However, gasification suffers from various issues, including slower carbon conversion, poor syngas quality, lower heating value and higher emissions. Multiple factors affect gasification performance, such as the selection of gasifiers, feedstock’s physicochemical properties and operating conditions. In this review, the status of gasification, key gasifier technologies and the effect of solid-fuel (i.e., coal, biomass and MSW) properties on gasification performance are reviewed critically. Based on the current review, the co-gasification of coal, biomass and solid waste, along with a partial utilisation of CO2 as a reactant, are suggested. Furthermore, a technological breakthrough in carbon capture and sequestration is needed to make it industrially viable.

“…Salazar et al carried out a heat exchanger network synthesis analysis on the WGS reaction system. In that study, a superstructure approach for optimal process synthesis was used to specify an optimal design that reduces the energy costs by approximately 28% when compared to the base case configuration [56]. Liszka and Ziebik formulated a net present value-based cost function to optimize the IGCC process with multiple gasifier systems [57].…”

Conceptual Design of the Coal to Synthetic Natural Gas (SNG) Process Based on BGL Gasifier: Modeling and Techno-Economic Analysis

et al. 2016

Developing coal to synthetic natural gas (SNG) projects in China could alleviate the conflict between supply and demand of natural gas. The coal to SNG process based on Lurgi gasifier (Lurgi process) has been commercially implemented. However, low energy efficiency and high production cost restricted expansion of Lurgi processes. BGL gasifier developed based on Lurgi gasifier is considered to be more appropriate for coal to SNG projects. In this work, a novel BGL gasifier based coal to SNG process (BGL process) is proposed and simulated based on rigorous kinetics models. Based on simulation, techno-economic analysis and comparison is conducted over the conventional Lurgi process. The results show that objective energy efficiency of the BGL process is 8% larger than that of the Lurgi process, while increase of general energy efficiency is not obvious. Considering the income of product, ROI (return on investment) of the BGL process is 3% higher than that of the Lurgi process. However, the Lurgi process can produce more byproducts. If considering values of these byproducts, the BGL process will not be economically competitive.
