“…As well, direct fuel use of DME requires pressurization due to low vapor pressure and methanol is slightly corrosive and more toxic than gasoline. However, the minor modifications required would be built from the existing infrastructure and would be cheaper and more feasible than building from the ground up (Zhu et al, 2011). As well, when determining process feasibility it is important to weigh societal, economic and environmental factors together.…”

“…At these conditions methanol conversions can approach 70-85% (mol basis), nearing equilibrium values. Selectivity is also usually high with a small amount of formaldehyde being produced (Zhu et al, 2011;Farsi et al, 2011;Fazlollahnejad et al, 2009).…”

“…The choice of this reactor assumes that the reaction reaches equilibrium at these operating conditions. A sensitivity analysis was run to ensure consistent conversions and selectivities with literature data (Zhu et al, 2011). The effluent contains an equilibrium mixture of methanol, dimethyl ether, formaldehyde and water.…”

“…Operating conditions and economics for the pumping system are based on experimental work from the National Alliance for Algal Biofuels and Bio-Products (NAABB) operating on wet whole algae and lipid extracted algae. Lab-scale experiments indicate that algal slurries are not difficult to pump (Zhu et al 2013). …”

A comprehensive optimization model that can determine the most cost-effective and environmentally sustainable production pathways in an integrated processing network is needed, especially in the bioconversion space. We develop the most comprehensive bioconversion network to date with 193 technologies and 129 materials/compounds for fuels production. We consider the tradeoff between scaling capital and operating expenditures (CAPEX and OPEX) as well as life cycle environmental impacts. Additionally, we develop a general network-based modeling framework with nonconvex terms for CAPEX. To globally optimize the nonlinear program with high computational efficiency, we develop a specialized branch-and-refine algorithm based on successive piecewise linear approximations. Two case studies are considered. The optimal pathways have profits from 2$12.9 to $99.2M/yr, and emit 791 ton CO 2 -eq/yr to 31,571 ton CO 2 -eq/yr. Utilized technologies vary from corn-based fermentation to pyrolysis. The proposed algorithm reduces computational time by up to three orders of magnitude compared to general-purpose global optimizers.
