In a rotary drum for thickening pulp, the rotary drum may include drainage channels for delivering filtrate from a pulp mat on the rotary drum to a filtrate chamber at an end of the rotary drum, and includes a flat face valve and plenum chamber assembly in the filtrate chamber. The flat face valve can be juxtaposed against drainage outlets of the drainage channels, wherein the flat face valve does not block the drainage outlets during a majority of the rotation of the rotary drum. An opening on the flat face valve may extend through the front surface and be aligned with the drainage outlets to provide a fluid passage through the flat face valve and to a plenum chamber behind the flat face valve such that air in the filtrate is collected in the upper portion of the plenum chamber and removed from the rotary drum.

A paper machine screen which is formed as a transverse thread-bound, multi-layer fabric. Binding transverse threads extend respectively both in an upper fabric layer and in a lower fabric layer and hereby bind the lower fabric layer to the upper fabric layer. The binding transverse threads form functional transverse thread pairs within the total repeat, the transverse threads of which alternately complete the first weave. In the total repeat, the functional transverse thread pairs in the upper fabric layer are arranged in groups of respectively two or more functional transverse thread pairs arranged directly one after another, when seen in a longitudinal direction.

This proposal aims to develop high-potential novel and environmentally benign technologies and processes for post-combustion CO2 capture leading to real breakthroughs. The proposal includes all main separation technologies for post-combustion CO2 capture; absorption, adsorption and membranes. Enzyme based systems, bio-mimicking systems and other novel forms of CO2 binding will be explored. For each technology we will focus on chosen set of promising concepts (four for absorption, two for adsorption and two for membranes). We aim to achieve 25% reduction in efficiency penalty compared to a demonstrated state-of-the-art capture process in the EU project CESAR and deliver proof-of-concepts for each technology. The various technologies and associated process concepts will be assessed using a novel methodology for comparing new and emerging technologies, for which limited data are available and the maturity level varies substantially. Based on the relative performance using various performance indicators, a selection of two breakthrough technologies will be made. Those two technologies will be further studied in order to do a more thorough benchmarking against demonstrated state-of-the-art technologies. A technological roadmap, based on a thorough gap analysis, for industrial demonstration of the two technologies will finally be established. HiPerCap involves 15 partners, from both the public and private sectors (research, academia, and industry), from 6 different EU Member States and Associated States, and three International Cooperation Partner Countries (Russia, Canada, and Australia). The HiPerCap consortium includes all essential stakeholders in the technology supply chain for CCS: power companies, RTD providers, suppliers, manufacturers (of power plants, industrial systems, equipment, and materials), and engineering companies.

The main objective of NeoCel project is to develop innovative and techno-economically feasible alkaline processes enabling the sustainable production of higher quality eco-innovative textile fibres from reactive high-cellulose pulps and integration of these processes with pulp mills. Targets for the development of NeoCel processes are: - wet strength of fibres higher than the wet strength of standard viscose, competing with cotton properties. - lower environmental impact than any other type of existing textile fibre - Reduction of production cost by at least 15% compared to that of best available technology (BAT) viscose The targets will be met through development of adapted pulps with high reactivity/solubility in alkaline water-based solutions, advanced dissolution process to maximize cellulose concentration, novel cellulose regeneration chemistry enabling both recovery of process chemicals and increased strength properties of the spun fibre, design for integration of textile fibre production with the pulp mill for minimized environmental impact, increased energy efficiency and reduced chemical consumption through system analysis using software models of theoretical mills. In NeoCel, a consortium with raw material processing companies, chemical suppliers, equipment producers, SMEs and world-leading research institutes has formed to develop the processes for large scale manufacturing of eco-innovative textile fibres. The consortium expects that a successful NeoCel project will enable creation of 75 000 new jobs and a turn-over increase of 9.5 billion for European forest products, textile and clothing industries within 15 years. However, already within 3 years, the consortium partners expect their joint turnover to increase by 170 MEuro

SmartLi aims at developing technologies for using technical lignins as raw materials for biomaterials and demonstrating their industrial feasibility. The technical lignins included in the study are kraft lignins, lignosulphonates and bleaching effluents, representing all types of abundant lignin sources. The raw materials are obtained from industrial partners. The technical lignins are not directly applicable for the production of biomaterials with acceptable product specifications. Therefore, pretreatments will be developed to reduce their sulphur content and odour and provide constant quality. Thermal pretreatments are also expected to improve the material properties of lignin to be used as reinforcing filler in composites, while fractionating pretreatments will provide streams that will be tested as plasticizers. Lignin is expected to add value to composites also by improving their flame retardancy. The development of composite applications is led by an industrial partner. Base catalysed degradation will be studied as means to yield reactive oligomeric lignin fractions for resin applications. The degradation will be followed by downstream processing and potentially by further chemical modification aiming at a polyol replacement in PU resins. Also PF type resins for gluing and laminate impregnation, and epoxy resins will be among the target products. Full LCA, including a dynamic process, will support the study. The outcome of the research will be communicated with stakeholders related to legislation and standardisation.
