MOQAPRO

Methods and tools for quantitative and qualitative woodchips production monitoring in a large scale supply chain
Funder: French National Research Agency (ANR)Project code: ANR-12-BIME-0007
Funder Contribution: 970,475 EUR
Description

MOQAPRO’s main target is a large scale and integrated approach, from forest land to energy mills, of quantity and quality monitoring of the woodchips production chain, due to specific methods and tools development for quality measures and production management. Quality monitoring for woodchips is mainly depending on moisture measurement, at every step of the production chain. Size grading and fermentation measurement are also needed. For quantity aspects, volume and mass have to be precisely known, which is not as easy as it could seems, because of woodchips mass variations, and large scale heap characteristics. Monitoring MWh unit all over this production chain means a permanent measurement of woodchips mass and moisture. Good methods for roadside or platform storage, and quality packing, must be precisely described and estimated. Forest biomass for energy production takes various forms and is changing is characteristics during the production chain. This is why detailed information is needed from harvesting operations and logistics organizations at key steps. Using these data, a specifications document will be elaborated, and on this basis, a specific information system for woodchips storage optimization will be developed. Further, for platform storage monitoring, new methods for woodchips heap visible volume must be tested. The goal is here to adapt technologies to rough storage sites conditions, and to allow automatics and economics frequent measurement, for big scale volume. Two very innovating tools will be developed for moisture measurement. They will be a result of OMICAGE’s previous project first conclusions, due to good results of the demonstrator used in laboratory conditions for dynamic woodchips flow. The measurement principle has been registered in a deposited patent. It is based on electromagnetic waves, and is developed for moisture evaluation at woodchips crushing machine exit system. It’s now necessary to develop this technology for many woodchips types, and various worksites conditions, to get a pre industrial prototype. A second tool is needed for moisture measurement of more important woodchips volume, on static conditions. This tool will be developed with a laboratory prototype first step, using same technologic basis, but with important adaptations. A new prototype, on scale 1 will be tested on worksites conditions, especially on storage platform. In both tools, mass measurement tolls will be integrated in each prototype, allowing Mwh unit monitoring new possibilities. Before all this, and as a complement to the state of art already done, and to the proper expertise of this project partners, investigations will be led in various countries, to identify production methods, monitoring tools which could be adapted to French forest conditions. For further development of industrialization steps, contacts and partnerships will be looked for, especially with forest harvesting and crushing machines constructors. Results of this project are eagerly awaited by many actors of woodchips production chain. It is highly strategic to give innovating solutions for these monitoring aspects, especially on moisture measurement, to allow high industrial scale level of forest biomass energy production, in liable economic conditions.
