“…However, the process by which it is produced from biomass must be economical to achieve widespread commercialisation. [14] The downstream separation section, on the other hand, is more complex and inherently more expensive due to the presence of highly volatile carbon dioxide (CO 2 ) and DME products. [6][7][8] While increasing the size of production facilities leads to lower production costs due to economy of scale benefits, the large transportation costs limit the optimum size of biomass facilities to intermediate production rates.…”

A ternary semicontinuous system for the separation of bio-dimethyl ether from methanol and water is presented. The performance of eight potential control configurations, including the application of temperature inferential control, is evaluated. Dynamic simulations of the semicontinuous system and associated control scheme demonstrate that the temperature inferential control configuration is effective in achieving the separation objectives while remaining within operational limits. The semicontinuous system using the inferential temperature control scheme is simulated and shown to be economically preferable to the traditional continuous process for a range of production rates.

“…The catalyst used was a Cu‐based bifunctional powder catalyst; 65 % of the CO was converted, and the DME selectivity was 76 %. Slurry reactors and bifunctional catalysts for the single‐step synthesis of DME have also been investigated, for example, JFE developed a new process that consists of a slurry bed reactor coupled with optimum reaction heat control technology to produce DME efficiently and economically …”

9Process simulation of a single-step synthesis of DME based on CO 2 -enhanced gasification of 10 rice straw was conducted using Aspen Plus TM . The process consists of gasification unit, heat 11 recovery unit, gas purification unit, single-step DME synthesis, and DME separation unit. In the 12 simulation, highly pure DME was produced by the control of CO 2 concentration in syngas to a 13 very low level prior to synthesis. A gasification system efficiency of 36.7% and CO 2 emission of 14 1.31 kg/kg of DME were achieved. Bio-DME production based on CO 2 -enhanced gasification of 15 biomass was found to be more cost-effective as it required 19.6% less biomass than that of DME 16 production based on conventional biomass gasification. The performance and environmental 17 benefits of the proposed process could be further improved by the utilization of unreacted gases 18 and the handling of CO 2 generated via incorporating poly-generation concept or carbon storage, 19 which could also potentially improve process economics. 20

“…For dimethyl ether, Ekbom (2005) presented a cost-effective route by carrying out case study, and the effect of oxidant addition on biomass gasification was investigated by performing simulations (Ju et al, 2009). Consonni et al (2009) conducted mass-energy balance simulations and economic analyses of biorefineries based on seven configurations; Naqvi et al (2010) studied DME production technologies by black liquor gasification, which was integrated with the pulp mill facility.…”

Dimethyl ether (DME) is a clean and efficient synthetic fuel with the potential to substitute liquefied petroleum gas (LPG) and diesel. From both the environmental and economic viewpoints, there is a strong preference to use biomass as the feedstock of synthetic fuels. In this study, state-of-the-art technologies were surveyed and a superstructure representation for the DME production process involving the use of biomass as a feedstock was investigated. Moreover, a mixed-integer nonlinear programming (MINLP) model was proposed for developing a DME production process based on biomass gasification. A combination of optimal technologies was adopted; detailed studies are presented to demonstrate the key features of the proposed superstructure.
