heal.abstract	This work attempts to approach a novel concept; the design of the so-called “lignin-first” biorefineries. Biorefineries are emerging day by day as alternative means of producing valuable products for society. Lignin-first biorefineries aim towards the holistic utilization of biomass by applying mild treatments to the lignocellulosic components. This approach has been providing with efficient monomer yields from all fractions of biomass. The aim of this project is to study the effect of a lignin-first pretreatment approach on plant economics. For this reason, promising experimental results of biomass processing are modelled in the process engineering software Aspen Plus v8.8 as two integrated pilot scale biorefineries. Both biorefineries operate at a capacity of 87600 metric tons per year. However, one biorefinery utilizes a traditional organosolv pretreatment via the utilization of a novel “green” solvent – γ-valerolactone. The other biorefinery, utilizes the lignin-first approach by using γ-valerolactone and formaldehyde as a co-solvent. The resulting streams from the pretreatment sections are separated and head towards upgrading. Both biorefineries eventually transform biomass’s building blocks into the following platform chemicals: Levulinic Acid, Furfural and lignin-derived aromatics. After modelling the process flowsheet for each case, pinch analysis is performed in order to identify utility requirements. Capital and operating costs are calculated based on experimental data and the help of aspen plus economic analyzer in order to determine the feasibility of both scenarios.	en
