Integration of biomass gasification with a Scandinavian mechanical pulp and paper mill – Consequences for mass and energy balances and global CO2 emissions

Isaksson, Johan; Pettersson, Karin; Mahmoudkhani, Maryam; … - In: Energy 44 (2012) 1, pp. 420-428

The Scandinavian mechanical pulp and paper industry has been facing great challenges during the past decades, mainly because of declining demand for newsprint, and higher prices on raw material and energy. One way of increasing profitability is to produce more value-added products besides the...

Techno-economic analysis of a kraft pulp-mill-based biorefinery producing both ethanol and dimethyl ether

Fornell, Rickard; Berntsson, Thore; Åsblad, Anders - In: Energy 50 (2013) C, pp. 83-92

A conceptual biorefinery, based on repurposing a kraft pulp mill, has been studied. In the process an alkaline pre-treatment unit separates the incoming wood raw-material to a cellulose-rich pulp and a residue liquor containing dissolved lignin. The pulp is sent to an ethanol line, while the...

Comparison of black liquor gasification with other pulping biorefinery concepts – Systems analysis of economic performance and CO2 emissions

Pettersson, Karin; Harvey, Simon - In: Energy 37 (2012) 1, pp. 136-153

Black liquor gasification (BLG) is being developed as an alternative technology for energy and chemical recovery in kraft pulp mills. This study compares BLG – with downstream production of DME (dimethyl ether) or electricity – with recovery boiler-based pulping biorefinery concepts for...

Systems analysis of integrating biomass gasification with pulp and paper production – Effects on economic performance, CO2 emissions and energy use

Wetterlund, Elisabeth; Pettersson, Karin; Harvey, Simon - In: Energy 36 (2011) 2, pp. 932-941

This paper evaluates system aspects of biorefineries based on biomass gasification integrated with pulp and paper production. As a case the Billerud Karlsborg mill is used. Two biomass gasification concepts are considered: BIGDME (biomass integrated gasification dimethyl ether production) and...

CO2 emission balances for different black liquor gasification biorefinery concepts for production of electricity or second-generation liquid biofuels

Pettersson, Karin; Harvey, Simon - In: Energy 35 (2010) 2, pp. 1101-1106

Black liquor gasification (BLG) is currently being developed as an alternative technology for energy and chemical recovery at chemical pulp mills. This study examines how different assumptions regarding systems surrounding the pulp mill affect the CO2 emission balances for different BLG...

Assessment of the energy and economic performance of second generation biofuel production processes using energy market scenarios

Heyne, Stefan; Harvey, Simon - In: Applied Energy 101 (2013) C, pp. 203-212

In this paper performance assessment of second generation biofuel production using energy market scenarios and system-level performance indicators is proposed. During biofuel production a number of products and services can be co-generated while import of energy services (e.g. electricity and...

Framework methodology for increased energy efficiency and renewable feedstock integration in industrial clusters

Hackl, Roman; Harvey, Simon - In: Applied Energy 112 (2013) C, pp. 1500-1509

Energy intensive industries, such as the bulk chemical industry, are facing major challenges and adopting strategies to face these challenges. This paper investigates options for clusters of chemical process plants to decrease their energy and emission footprints. There is a wide range of...
