Chemical and energy conversion systems based on microchannel process technology (MPT) demonstrate high performance in applications in which rates are controlled by diffusive heat and mass transfer flux. MPT-based heat exchangers, absorbers/desorbers and chemical reactors all benefit from process...

The United States is abundant in biomass resources. The Pacific Northwest National Laboratory (PNNL) have been conducting research on conversion of biomass into chemical products and advanced fuels for several decades. In this presentation, the author will discuss significant research advancement,...

Water, once considered a nearly inexhaustible resource, is becoming increasingly limited, and water requirements for electricity production must compete with other demands, such as agriculture and sanitation. The Department of Energy's (DOE) Fossil Energy Program is conducting a considerable R&...

Membrane fouling and flux decline are undesirable, albeit inevitable, problems in membrane filtration processes for water treatment. The development of low fouling membranes, the design of high efficiency modules, the selection of optimal operational strategies, and several improvements made in...

Water conservation is one of important sustainability issues in production and/or conversion of biomass to fuels. In this presentation, the author will use micro-algae growth and fermentation production of ethanol fuel as two examples to elaborate application of respective microfiltration and...

Over the last few years, our eyes have been opened to global climate change, and to the environmental and geopolitical issues surrounding sustainability. As an example, by 2015, more than half of the regions in the world will experience some level of stress in water supply and management. Similar...

Over the last few decades, LNG has vaulted onto the world stage as a viable candidate for future energy needs. Scores of studies have been done to illustrate the potential consequences of an accidental release of LNG. Some excellent studies have been reported, but uncertainties still exist because...

A number of notable features are addressed that may be encountered in designing a large aboveground full containment LNG storage tank. The size and thickness of the inner tank, which is made of 9% Ni, is closely related to the specifications of design codes. The recent revisions of the relevant...

Production of power from coal inevitably generates carbon dioxide (CO2) as a by-product. To mitigate global climate change, this CO2 must be captured and sequestered. With current technologies, separating CO2 from flue gas accounts for about 70% of the total cost for CO2 capture and sequestration...

Gas Technology Institute (GTI) and PoroGen Corporation are jointly developing a novel hybrid membrane – absorption process for pre- and post-combustion CO2 capture (Carbo-Lock™ process). The novel Carbo-Lock™ process combines advantageous features of both absorption and membrane processes to...
