The Department of Natural Resource Funding , operating under the FIP applied title Natural Resources Canada , is the ministry of the government of Canada responsible for natural resources, energy, minerals and metals, forests, earth science, mapping and remote sensing. It was created in 1995 by amalgamating the now-defunct Departments of Energy, Mines and Resources and Forestry. Natural Resources Canada works to ensure the responsible development of Canada's natural resources, including energy, forests, minerals and metals. NRCan also uses its expertise in earth science to build and maintain an up-to-date knowledge base of our landmass and resources." To promote internal collaboration, NRCan has implemented a departmental wide wiki based on MediaWiki. Natural Resources Canada also collaborates with American and Mexican government scientists, along with the Commission for Environmental Cooperation, to produce the North American Environmental Atlas, which is used to depict and track environmental issues for a continental perspective.Under the Canadian constitution, responsibility for natural resources belongs to the provinces, not the federal government. However, the federal government has jurisdiction over off-shore resources, trade and commerce in natural resources, statistics, international relations, and boundaries. The current Minister of Natural Resources is Greg Rickford as of March 2014.The department is governed by the Resources and Technical Surveys Act, R.S.C., c.R-7 and the Department of Natural Resources Act, S.C. 1994, c. 41."structured along business lines according to types of natural resources and areas of interest." The department currently has these sectors: Canadian Forest Service Corporate Management and Services Sector Earth science Sector Energy Sector Innovation and Energy Technology Sector Minerals and Metals Sector Science and Policy Integration Public Affairs and Portfolio Management Sector Shared Services Office Geographical Names Board of Canada↑ ↑ ↑ Wikipedia.

A system and method for capturing and separating carbon dioxide from mixed gas streams. The gas stream is processed in a structure including a compression module comprising a plurality of compressors, intercoolers and inter-stage condensate separators. The flow path from the compression module includes a plurality of flow separators, gas stream splitters, heat exchangers and at least a first mixer and a first expander. The gas stream is sequentially compressed and cooled to form process condensate and separate it from the compressed gas stream. The gas stream is further dried and cooled to liquefy carbon dioxide and separate it from the non-condensable portion. Selective expansion of liquid carbon dioxide streams provides cooling for the system, and further energy efficiency is achieved by selective recycling of portions of gas streams, allowing for compact equipment and economical operation, while providing for high purity product streams of carbon dioxide.

A system using hybrid Rankine cycles is provided. The system includes a first Rankine cycle system using a first working fluid, the first system producing exergy loss and residual energy from at least one of turbine extraction, turbine condensation and boiler flue gas; and a second Rankine cycle system using a second working fluid to recover the exergy loss and residual energy. The second working fluid comprises a first stream and a second stream, wherein the first stream exchanges heat with the first system via at least one first heat exchanger, and the second stream exchanges heat with the first system via the at least one first heat exchanger and at least one second heat exchanger. A turbine of the first system is configured to allow the first working fluid to exit at a sufficiently high pressure and temperature to provide heat to the second system instead of expanding to a low pressure and temperature and discharging heat to ambient using a condenser.

A method and system for improving high excess air combustion system efficiency, including induration furnaces, using a re-routing of flue gas within the system by gas recirculation. Flue gas is drawn from hot system zones including zones near the stack, for re-introduction into the process whereby the heat recovery partially replaces fuel input. At least one pre-combustion drying zone, at least one combustion zone, and at least a first cooling zone exist in these furnaces. At least one exhaust gas outlet is provided to each pre-combustion drying and combustion zone. At least part of the gaseous flow from each system zone exhaust outlet is selectively delivered to an overall system exhaust, the remaining flow being selectively delivered via recirculation to cooling zones. Recirculation flow is adjusted to meet required system temperatures and pressures. The method and system provide efficiency improvements, reducing fuel requirements and greenhouse gas emissions.

Provided is a process for recovering metals from solid radioactive waste, preferably uranium, cesium, mercury, thorium, rare earths or combinations thereof. The process comprises a leaching step and a separation step. The leaching step comprises contacting the solid radioactive waste with an aqueous inorganic acid and a leaching salt to produce a mixture of a metal-rich leachate and a metal-poor waste, which are separated in the separation step. Also provided is a process for recovering metals from solid radioactive waste comprising an attrition step, a leaching step, a washing step, a combination step and a recovery step.

Disclosed are methods and apparatuses for analysis of synthetic ropes, cords, slings, cables and belts (collectively termed ropes) including but not limited to ropes for bearing loads as well as fibre optic cables. The ropes are provided with one or more elements for magnetic detection, wherein the magnetic detection elements each comprise a metal fibre or an appropriately treated synthetic fibre. The methods and apparatuses encompass detection of induced or residual magnetism or magnetic flux in the magnetic detection element(s), to sense for example lay length and/or damage, breakage or wear of the magnetic detection element(s), indicative of the condition of the rope.

Disclosed is a method for improving a heavy hydrocarbon, such as mined bitumen, to a lighter more fluid product and, more specifically, to a hydrocarbon product that is refinery-ready and that meets pipeline transport criteria without requiring the addition of diluent. The invention is suitable for enhancing recovery from mined Canadian bitumen, but has general application for processing any heavy hydrocarbon, converting the heavy hydrocarbon to a product that is more suitable for pipeline transport. The invention is directed to a process for converting a heavy hydrocarbon stream into a pipelineable product, said process comprising: (a) using a froth treatment process to separate bitumen present in the heavy hydrocarbon stream from water creating a solvent/bitumen stream and a water-rich stream; (b) extracting the solvent/bitumen stream to generate multiple product streams comprising: i) a bitumen bottoms stream; ii) a virgin heavy vacuum gas oil stream; iii) a light virgin vacuum gasoil stream; and iv) a light virgin atmospheric gas oil stream; (c) converting, in a conversion unit, a portion of the heavy vacuum gas oil stream and/or bitumen bottoms obtained from step (b) to produce a stream of lighter hydrocarbons; and (d) blending a portion or all of the virgin heavy vacuum gas oil stream, the light virgin vacuum gasoil stream, the light virgin atmospheric gas oil stream from step (b) and the stream of lighter hydrocarbons produced in step (c) to create a pipelineable product.


The invention disclosed relates to a novel composition and use thereof, for the attraction and detection of emerald ash borer, Agrilus planipennis Fairmaire. The composition comprises (3Z)-dodecen-12-olide and ash foliar or cortical volatiles (green leaf volatiles) associated with a prism trap of a color in the green range of the visible light spectrum. A significant increase in the capture of male A. planipennis is achieved when traps were deployed in the upper tree canopy. This invention is the first demonstration of increased attraction with a combination of a pheromone and a green leaf volatile in a Buprestid species.
