This study evaluates the potential for reducing life cycle greenhouse gas (GHG) emissions of biomass gasification-based methanol production systems based on energy balances. Configurations which are process integrated with a chemical cluster have been compared to stand-alone units, i.e. units...

A systematic analysis of interrelations between different process steps in the biomass gasification and methanol synthesis chain was made. The energy performance of the system is assessed by reviewing previous studies and analysing a case study. Implications of technology choices and process...

The goal of this study is to evaluate co-firing of gasified CO2 neutral biofuel in a retrofitted natural gas combined cycle (NGCC) combined heat and power (CHP) unit designed for natural gas operation. This type of situation may be particularly relevant if future CO2 abatement policies require...

Rising fuel prices, increasing costs associated with emissions of green house gases and the threat of global warming make efficient use of energy more and more important. Industrial clusters have the potential to significantly increase energy efficiency by energy collaboration. In this paper...

In this paper, we propose a systematic approach to study how the development in terms of cost and proven functionality of emerging energy technologies affects the optimal choice and timing of investment decisions at an industrial plant today. The methodology used is based on stochastic...

Petroleum oil refineries account for almost 8% of the total CO2 emissions from industry in the European Union (EU). In this paper, the European petroleum refining industry is investigated and the prospects for future CO2 abatement in relation to associated infrastructure are assessed. A more...

In this paper, the global CO2 effect of integrating different biomass gasification concepts to meet an increasing demand of hydrogen in an oil refinery is examined and presented in comparison with a conventional steam reformer. The studied refinery is a hydro skimming refinery with a future...

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...

The impact on CO2 emissions of integrating new technologies (a biomass-to-Fischer–Tropsch fuel plant and a post-combustion CO2 capture plant) with a complex refinery has previously been investigated separately by the authors. In the present study these designs are integrated with a refinery...

Significant energy savings can be achieved in the pulp and paper industry through process integration. The aim of this paper was to investigate how much seasonal variations in the process influence the potential for making energy savings. The hot and warm water system in a market pulp mill has...
