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 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.

The invention relates to a method and apparatus for measuring lay length of a wire rope having a number or external strands to form a rope having spiral grooves in the surface between the strands. A magnetic flux circuit is generated, part of which is formed within a region of the advancing wire rope. Variations of magnetic field around the region of the rope or variations of magnetic flux entering or leaving the rope are sensed by at least two sensors arranged around the rope. Signals from the sensors are subtractively combined to eliminate variations due to off-axis movements of the rope, and the combined signals reveal an oscillating pattern due to the undulating surface of the rope. Linking the oscillating pattern to distance along the rope reveals the lay length, which corresponds to a number of oscillations which is the same as the number of strands at the surface.

The invention relates to a hybrid reverse flow catalytic apparatus having two reaction zones: a homogeneous reaction zone in porous ceramic and a heterogeneous reaction zone with catalyst, arranged in two different catalyst beds. A first catalytic bed located in a central region of the reactor is provided with a low activity catalyst and a second catalyst bed located in a peripheral region of the reactor is provided with a high activity catalyst. The provision of two catalyst beds containing different catalysts reduces the effect of radial temperature gradients in the reactor and improves the overall efficiency of the reactor. The invention also relates to method of performing catalytic and thermochemical reactions in said apparatus.

The invention relates to modifications of a non-ammoniacal thiosulfate process of leaching precious metals (e.g. gold or silver) from precious metal-containing ores. The process involves leaching the ore with an aqueous lixiviant containing a soluble thiosulfate other than ammonium thiosulfate, a copper compound and an organic compound that serves as a copper ligand (i.e. a ligand-forming compound). Four modifications of this process are effective for increasing the amount of precious metal that can be extracted, reducing the consumption of materials, or for improving the rate of extraction. These four process, which may be used singly or in any combination, include (a) additions of soluble lead (e.g. as lead nitrate), (b) additions of thiourea, (c) increases in dissolved oxygen, and (d) increases of temperature at ambient pressure. This avoids the use environmentally harmful chemicals and allows for extraction from a variety of ores, e.g., containing substantial amounts of sulfides and/or quartz.

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.
