BioODRI: forestry meets steel : A techno-economic study on us of biomass gasification to produce a gas sutiable for production of CO2 lean iron

Konferensbidrag (refereegranskat)abstract
- A major part of the world’s iron production is presently using fossil reductants. The climate effect would be improved if renewable raw material could be used instead. One way could be to gasify biomass and use the gas to produce DRI (Direct reduced Iron). This is studied in a cooperative project. LTU, MEFOS, ETC and five industries in the areas forestry & pulp, mining, iron and gas are involved. The production chain Biomass production and distribution-Gasification-DRI production-DRI use is investigated in four work packages: WP1: Biomass supply, WP2: Gasification, WP3: Metallurgical processes and WP4: Process integration. The paper will focus on the studies and modeling of biomass supply, harvesting and transport and gasification as well as on the system studies. The use of the gas in the metallurgical application is briefly described as background.

Forestry meets Steel. A Technoeconomic study of the possible DRI production using biomass
- 2015

Konferensbidrag (refereegranskat)abstract
- The possibility to produce DRI using gasified Biomass is studied in a cooperative project. LTU, MEFOS, ETC and five industries in the areas forestry & pulp, mining, iron and gas are involved. The production chain Biomass production and distribution -Gasification-DRI production-DRI use is investigated in four work packages:WP1: Biomass supply: A large amount of Biomass has to be delivered into a single site to exchange a large amount of fossil reductant. It is important to use forestry by- products as a major part of round wood is reserved for other uses. Harvesting, logistics and economics have to be considered. Available data were collected and used to make a system model on harvesting treatment and transport. The simulations indicated that the supply of residuals is possible but will need material from a large part of the north Sweden wood area. WP2: Gasification. The aim is to use to produce hot gas that can be used directly. Pilot experiments are carried out using oxygen in an entrained flow gasifier. WP3: Metallurgical processes. Reduction tests are carried out with gas that can be produced in the gasifier. The limitations of the gas content are studied as well as the effect on DRI. Also the suitability of the DRI product is evaluated WP4: Process integration. A system model is built using the results from work packages 1-3 and used for technical economic optimization the whole system harvesting-transport-gasifier-direct reduction- use of DRI. The process chain is technically possible; however there are problems to be solved, e.g., gas quality vs. demands from DRI process, Biomass supply and logistics. The result is important to evaluate for industrial application, but also to get information of the effect of different governmental control instruments.

Konferensbidrag (refereegranskat)abstract
- One way for the automotive industry to cope with the demand of a more structured information handling is to adjust model-based development (MBD) to multidisciplinary needs. Many of the issues faced in this transition are as much organizational and managerial as they are technical. In a case study carried out at a global automotive manufacturer a project to improve the electrical and electronics (EE) development has been followed and analyzed. The project originated from different needs identified by management in their ongoing work effort towards MBD as well as by developers who experienced that tools did not support their work situation. This paper describes how the introduction of a new tool support was made in a project carried out within EE development, further it reports on benefits achieved by using the tool. Both the effect on the work of affected EE developers and the expansion of a new information model are discussed, leaving important implications for management. Success keys for putting new support tools into practice are identified here and include; a bottom-up approach, user involvement from the beginning, focus on the individual needs and adaptation to current work practice. Further, management support and adequate resources are essential for extracting long-term benefits.
