The Energy and Environmental Research Center in Grand Forks, North Dakota, United States is a research, development, demonstration, and commercialization facility for energy and environment technologies development. The center is a nonprofit division of the University of North Dakota.The center was founded in 1951 as the Robertson Lignite Research Laboratory, a federal facility under the United States Bureau of Mines. It became a federal energy technology center under the United States Department of Energy in 1977 and was defederalized in 1983. The center employs approximately 235 employees.The EERC conducts research, development, demonstration, and commercialization activities involving zero-emissions coal conversion; CO2 capture and sequestration; energy and water sustainability; hydrogen and fuel cells; advanced air emission control technologies, emphasizing SOx, NOx, air toxics, fine particulate, CO2, and mercury control; renewable energy; wind energy; water management; flood prevention; global climate change; waste utilization; energy efficiency; and contaminant cleanup.The EERC is located on more than 15 acres of land on the southeast corner of the UND campus in Grand Forks, North Dakota, and houses 254,000 square feet of laboratories, fabrication facilities, technology demonstration facilities, and offices. The EERC has a current contract portfolio of over $257 million and, and the EERC's estimated regional economic impact is $91.2 million. Since 1987, the EERC has had more than 1,100 clients in 50 states and 51 countries. Wikipedia.

Energy and Environmental Research Center | Date: 2017-04-19

In various embodiments, the present invention relates to heat dissipation systems including a hygroscopic working fluid and methods of using the same. In various embodiments, the present invention provides a method for heat dissipation using a hygroscopic working fluid. The method can include transferring thermal energy from a heated process fluid to the hygroscopic working fluid in a process heat exchanger, to form a cooled process fluid. The method can include condensing liquid from a feed gas on a heat transfer surface of a feed gas heat exchanger in contact with the cooled process fluid, to form a cooled feed gas, the heated process fluid, and a condensate. The method can include dissipating thermal enegy from the hygroscopic working fluid to a cooling gas composition with a fluid-air contactor. The method can include transferring moisture between the hygroscopic working fluid and the cooling gas composition with the fluid-air contactor. The method can include adding at least part of the condensate to the hygroscopic working fluid.

Computational modeling is a valuable tool for understanding atomic-level catalytic processes on metal oxides. Carboxylic acid adsorption and enolization with varied degrees of α branching on monoclinic zirconia's most important surfaces, (̄111), (111), and (̄101), have been studied by the density functional theory (DFT). Carboxylates on zirconia (̄111) and (111) surfaces are preferentially stabilized in the bidentate bridging mode, with O-H bond dissociation and hydrogen bonding to a 2-fold coordinated (2-fc) lattice oxygen. Carboxylic α hydrogen abstraction by another 2-fc lattice oxygen results in enolization of adsorbed carboxylates most readily on the (̄111) surface of monoclinic zirconia with activation energy ∼25 kcal/mol, which is not sensitive to acid branching. Enolization on the (111) surface requires higher activation energy, 29-33 kcal/mol depending on acid branching. This study demonstrates the origin of an important intermediate in the carboxylic acid ketonization mechanism - often named "surface ketene". © 2011 American Chemical Society.

A promoted activated carbon sorbent is described that is highly effective for the removal of mercury from flue gas streams. The sorbent comprises a new modified carbon form containing reactive forms of halogen and halides. Optional components may be added to increase reactivity and mercury capacity. These may be added directly with the sorbent, or to the flue gas to enhance sorbent performance and/or mercury capture. Mercury removal efficiencies obtained exceed conventional methods. The sorbent can be regenerated and reused. Sorbent treatment and preparation methods are also described. New methods for in-flight preparation, introduction, and control of the active sorbent into the mercury contaminated gas stream are described.
