“…However, there are still uncertainties on which reforming methodology is mostly suitable to be carried out in the second reformer. Luu et al [11] explored different reforming methodologies to solve the H 2 deficiency associated with DMR in MeOH production (i.e. H 2 /CO ratio is lower than the requirement of MeOH synthesis).…”

“…H 2 /CO ratio is lower than the requirement of MeOH synthesis). It was found that increasing the H 2 /CO ratio by adding pure H 2 or using BiR gave the best results in terms of CO 2 emission and methane uptake [11]. Jie and Tiejun used DMR to integrate with a biomass gasifier in order to control the overall syngas composition [33].…”

“…The primary liquid fuels such as MeOH and DME are attractive hydrogen carriers and may constitute the building blocks for higher hydrocarbons synthesis. In fact, DME production might arguably be a preferred option attributed to its ability to accept syngas under various compositions [11], while MeOH requires a syngas composition with a predetermined H 2 /CO ratio. Production of DME based on CCU starts with the preparation of syngas in dry methane reforming reactor (DMR) (reaction (b)) followed by simultaneous MeOH synthesis and dehydration step in one separate reactor [7].…”

“…Sourcing the required thermal energy from fossil fuels will undermine the sustainability of the DMR-DME route. It is estimated that the reformer duty (including the preheater and catalytic reactions) in DMR (reaction (b)) counts for approximately 55% of the total energy demand for the entire DME synthesis process [11,12].…”

A Comparative Exergoeconomic Evaluation of the Synthesis Routes for Methanol Production from Natural Gas

Abstract:Methanol is one of the most important feedstocks for the chemical, petrochemical, and energy industries. Abundant and widely distributed resources as well as a relative low price level make natural gas the predominant feedstock for methanol production. Indirect synthesis routes via reforming of methane suppress production from bio resources and other renewable alternatives. However, the conventional technology for the conversion of natural gas to methanol is energy intensive and costly in investment and operation. Three design cases with different reforming technologies in conjunction with an isothermal methanol reactor are investigated. Case I is equipped with steam methane reforming for a capacity of 2200 metric tons per day (MTPD). For a higher production capacity, a serial combination of steam reforming and autothermal reforming is used in Case II, while Case III deals with a parallel configuration of CO 2 and steam reforming. A sensitivity analysis shows that the syngas composition significantly affects the thermodynamic performance of the plant. The design cases have exergetic efficiencies of 28.2%, 55.6% and 41.0%, respectively. The plants for higher capacity can produce at a competitive price, while the design in Case I is hardly economically feasible. An exergoeconomic analysis reveals a high cost impact of the reforming unit, air and syngas compressors.
