Electrodialysis treatment of Kraft black liquo rusing Bipolar membrane

The production capacity of the Kraft process is one of the important measures in the pulp and paper industry. A promising method for increasing the production capacity of the Kraft process is to lower the load of the recovery boiler by means of extracting lignin from the black liquor (BL).

Development of a process for furfural production in an Integrated Forest Biorefinery

An integrated biorefinery for furfural production is an opportunity for Kraft pulp mills to create value from hemicellulose, a class of wood component that is currently burnt for energy. Furfural is one of the top bio-products with the potential to replace many industrial organic compounds that are currently produced from crude oil revenue. The objective of this work is to develop an optimized biorefinery process that can be best integrated into a Kraft pulp mill.

Detoxification of hemicellulosic hydrolysate for butanol production

High demands for fossil fuels and increasing concerns over global warming have renewed the interests in bio-butanol production from biomass resources as an alternative liquid fuel. Hemicellulose, as an inexpensive and abundant raw material, has great potential for being suitable fermentation substrate.

Systematic approach of equipment performance analysis using new Key Performance Indicators

The research proposal introduced is a development of a systematic method for evaluating the performance of Kraft process equipments from the point of 'view of energy, water and chemicals, using new and adapted key performance indicators. The objectives are (i) to develop new Key Performance Indicators adapted to the Kraft process operations and equipments to evaluate their performance regarding energy, chemicals and water utilization, (ii) to propose process improvement projects and validate their practicality with the mill engineers.

Development of a lignin biorefinery integrated into a Kraft pulp mill

Integrated lignin biorefineries present opportunities to increase the profitability of Kraft pulp mills through the diversification of product portfolio and improved sustainability. The purpose of this work is to develop optimized lignin biorefinery designs, which would be integrated into a Kraft pulp mill. A methodology combining process simulation, analysis and synthesis is proposed to achieve the purpose. Lignin acid precipitation process will be optimized in terms of chemical usage and yield and will be integrated into Kraft process.

Experimental characterization of thermal shims for space applications

MDA Montreal possesses a niche expertise on a wide variety of high-performance satellite telecommunication antennas. These antennas are exposed to extremely harsh environments. Some panels require a rigid mechanical assembly (i.e., nut and bolt fastening) but must preserve their thermal isolation for the proper operation of the antennas and to limit heat exchange towards the spacecraft. Relatively thick thermal shims or washers are currently inserted into these assemblies to almost completely block the heat flow between the two structures.

Effect of dam-rock interface irregularity of the seismic response of gravity dams

Dam failures may lead to catastrophic consequences, extending far beyond the immediate neighbourhood of the dam site due to sudden reservoir release or overtopping. The main objectives of this research project are: (i) to apply state-of-the-art simulation tools to investigate the seismic response of a real dam in Québec to formulate guidelines on the significance of including the effects of the irregularity of dam-rock interface and vertical component of earthquakes in the evaluation of the seismic response of dams.

Shot peening for fatigue life improvement and forming of aerospace structures

The principle objective of this collaborative project is to develop in collaboration with the industrial partners novel methodologies for characterizing the shot peening and peen forming processes. One part of the program is devoted to establish analytical and numerical models for the prediction of the shot peening and peen forming processes. Experimental campaigns are planned in order to qualify the effect of the shot peening parameters on the peening results as well as to validate the developed models.

Reduction-to-practice of embedded sensors and means of propagating analog signals over digital networks for aerospace

DreamWafer Prototyping WaferBoard™ is a “waffle iron” for prototyping electronic printed circuit board (PCB) systems. Simply place components (“dough”) in the WaferBoard™ and close the cover. "WaferBoard™ then senses the component contacts and recognizes the components and intelligently interconnects them (“cooks them”). The prototype (“waffle”) is now ready to be brought up and run. The WaferBoard™ will have saved the PCB development process weeks or months of time to market and tens to hundreds of thousands of dollars (or more).

Seismic design of eccentrically-braced frames with & without vertical ties for irregular buildings

The project aims at developing cost-effective steel seismic force resisting systems for multi-storey building structures that can achieved superior performance in terms of seismic stability and amplitude of damage. The system can be used for the construction of new structures or the seismic rehabilitation of existing structures. The system could also be implemented when adding storeys to existing buildings to increase the usable floor space. The internship will permit to develop and verify the applicability of the new systems to actual building constructions.
