Die im Rahmen dieses Projektes entwickelte Informatikplattform Wood2CHem ermöglicht die Konzeption innovativer Verfahren für die Verwertung des Rohstoffs Holz in einem ganzheitlichen und integrierten Ansatz.
Lay summary

Hintergrund
Aufgrund seiner Zusammensetzung und komplexen chemischen Struktur ist es möglich, aus Holz eine Vielzahl von Produkten mit hohem Mehrwert zu gewinnen. Das Konzept der Bioraffinerie bietet eine Möglichkeit zur Erweiterung des Portfolios aus Holz gewonnener Produkte. Dies geschieht mit Hilfe eines systemischen Ansatzes, der die bei der Produktion der verschiedenen Produkte entstehenden Synergien mittels Prozessintegration nutzt.
Die Entwicklung von Bioraffineriekonzepten stellt eine grosse Herausforderung dar. Eine Vielzahl von Prozesskonfigurationen, die innovative Verfahren und Umwandlungstechnologien umfassen, muss in einem ganzheitlichen Ansatz bewertet, integriert und optimiert werden, um die meistversprechenden Konzepte zu identifizieren.

Ziel
Unter Anwendung von Techniken des Prozessdesigns, der energetischen Integration und der multikriteriellen Optimierung strebt das Konsortium des Projektes Wood2CHem die Entwicklung einer Informatikplattform an, die es ermöglicht, systematisch die aussichtsreichsten Konfigurationen für Bioraffinerien zusammenzustellen und dabei die thermodynamische, wirtschaftliche und umweltschutztechnische Leistungsfähigkeit zu bewerten.
Die Entwicklung dieser integrativen Plattform erfolgt in Zusammenarbeit von Chemie- und Prozessdesign-Experten. Sie zielt auf die Integration der technologischen Entwicklungen im Bereich der Holzumwandlung ab und soll durch die Anwendung auf industrielle Fallstudien validiert werden.

Bedeutung
Das Projekt Wood2CHem betrifft die Entwicklung von Industriekonzepten. Daher ist es vornehmlich für Experten und Ingenieure im betreffenden Bereich von Interesse, die integrierte und innovative Konzepte für die rationelle Verwertung von Holz entwickeln wollen. Es ermöglicht die Konzeption und den Vergleich integrierter Verfahren. Durch einen globalen, auf die Konzeption von Verfahren ausgerichteten Ansatz bringt die Plattform alle Akteure zusammen, die die Perspektive einer industriellen Ökologie verfolgen.

Lay Summary (English)

Lead
Wood2CHem: A computer-aided platform for developing bio-refinery concepts The bio-refinery concept offers the timber industry numerous development opportunities by integrating the production of value-added products made from biomass. The computer-aided platform Wood2CHem, developed within the scope of this project, will help to devise innovative means for promoting wood as a resource using a holistic and integrated approach.
Lay summary

Background
Due to its composition and complex chemical structure, wood can be used to make a large number of value-added products. The bio-refinery concept proposes to widen the range of products derived from wood while adopting a systemic approach aimed at promoting syner-gies in the production of various products by integrating different processes. It therefore of-fers an enormous development potential for the wood sector and opens up many new markets.
The development of bio-refinery concepts poses a significant challenge. A large number of processes that integrate studies and technologies of innovative transformation need to be evaluated, integrated and optimised using a holistic approach before the most promising con-cepts can be identified.

Aim
By applying techniques from process engineering, energy integration and multi-objective op-timisation, the consortium of the Wood2CHem project proposes to develop a computer-aided platform for systematically generating the most promising bio-refinery models and evaluating their thermodynamic, economic and environmental performance.
This integrated platform will be developed by combining expertise in chemical engineering and process engineering. It is aimed at integrating technological developments of wood trans-formation and will be validated in industrial case studies.

Significance
The Wood2CHem project concerns the development of industrial concepts and will therefore primarily interest experts and engineers in the field who wish to develop integrated and inno-vative concepts for a rational promotion of wood. It will allow them to envisage and compare inegrated process chains. The platform will integrate all the actors wishing to assume the per-spective of industrial ecology.

Abstract

Wood represents a renewable and versatile raw material and energy resource. It is currently used to produce paper, fibres, building components and energy. But it can also be used to produce a wider range of chemicals. The conversion of wood into multi-product and services in a highly integrated plant is called “biorefinery”. The biorefinery concept gathers several important and very diverse fields of research: biofuel production, process systems engineering, biomass chemistry, biotechnology, environmental science… Due to the highly interdisciplinary dimension of this concept, requires a good knowledge of the conversion paths and the associated technologies available to transform lignocellulosic biomass into added value chemicals, biofuels and other energy services. As a consequence, it is today difficult to identify an optimal combination of transformation processes without the help of a computer aided systemic approach. Furthermore, considering the limited character of the resources, there is a need of such tool to build the necessary interface between research laboratories and industries (chemical industries, forestry industries, food industries) and ensure that the most competitive pathways are selected. Facing the combinatorial nature of the problem scenarios based approach are not anymore sufficient. There is therefore a crucial need to develop an interdisciplinary computer-aided platform to explore and compare systematically the possible conversion possible pathways from wood to chemicals and energy services taking into account mass and energy integration, resources availability and the corresponding supply chains and to generate their corresponding economic and environmental impact performance indicators.This project proposes to fill this gap by developing a computer-aided decision platform called “Wood2CHem”. Applying the process system design techniques, this platform will offer a support to design and synthetize optimal biorefinery concepts for the wood industry. Wood2CHem will be able to automatically define the appropriate combination of wood conversion processes to increase the wood feedstock productivity and revenue while limiting their environmental impact based on a set of user-defined constraints. It will also enable the optimization of the size and location of the multi-prodcut /multi-services biorefinery plants, realizing the perfect matches between the resources, the products and energy services value and the evaluation of the required capital investment. The Wood2CHem platform will integrate:Systematic methods to identify and analyse wood conversion chains to produce high added value chemicals and energy.A thermo-economic process modeling environment including a database of the process models required to realise and integrate the identified wood conversion pathways. This environment will allow to systematically integrate the results of the research and development in the field of wood conversion systems.Multi-objective optimization based process system engineering methods to design heat and mass integrated biorefineries systems, considering the wood supply chain, the localisation of the plant and the seasonal variations of the resources and the energy demands.An economic, health environment and safety assessment coupled with a life cycle impact assessment framework to compare the most attractive wood conversion chains.The originality of this project is to combine a fundamental scientific approach with technico-economic modelling tools and optimization techniques.
