This paper elaborates a concept for designing efficient large scale hydrogen liquefaction plants, based on dividing the process into 4 independent stages and finding the optimum solution for each stage. The main focus is put on the precooling stage. Not because of its power consumption, but because...

An experimental investigation was carried out to study the NO_x formation and reduction by primary measures for five types of biomass (straw, peat, sewage sludge, forest residues/Grot, and wood pellets) and their mixtures. To minimize the NO_x level in biomass-fired boilers, combustion experiments...

Enhanced CO₂ concentration in exhaust gas is regarded as a potentially effective method to reduce the high electrical efficiency penalty caused by CO₂ chemical absorption in post-combustion capture systems. The present work evaluates the effect of increasing CO₂ concentration in the exhaust gas of...

Accurate experimental data on the thermo-physical properties of CO₂-mixtures are prerequisites for development of more accurate models and hence more precise design of CO₂ capture and storage (CCS) processes. A literature survey was conducted on both the available experimental data and the...

Norwegian seafood products are important export products with regard to volume and value. More than 400 trucks of fresh fish products are weekly transported from Norway to European countries. The traditionally chilled fish is packed in boxes filled with approximately 30% ice (equivalent to...
