Improved solvent reaction kinetics and carbon capacity continue to be a major research interest for the scrubbing of CO2 in post-combustion processes. The DOE has set a new target for post-combustion CO2 capture of less than a 35% increase in the cost of electricity, while capturing at least 90% of...

The natural gas consumption is expected to grow significantly in the next decades. The need for building LNG import terminals with significant storage capacity is quite often a critical aspect due to restriction of land in the area of interest and environmental constraints. A new concept for the...

In order to capture the carbon content of coal, one option would be to gasify it with mixtures of, e.g. steam, CO2 and O2, to produce synthesis gas: the water-gas shift (WGS) reaction, CO + H2O <--> CO2 + H2, could then be used to increase the yield of hydrogen. In principle, if the WGS...

During resid conversion processes, such as visbreaking or hydroconversion, more saturated pendant groups are cracked off asphaltenes, making them less soluble. Meanwhile, the more saturated volatile liquids formed during the conversion are often nonsolvents for asphaltenes. As a result, these...

The analysis of LNG hazards, particularly in the context of onshore facility siting, has historically focused on the consequences of atmospheric pressure releases, such as would occur in the event of a storage tank breach. Recently, however, the issue of flammable vapor clouds formed by high-...

Koch Nitrogen, like every chemical plant, has a few rotating machines in the realm of critical where words like human safety, explosion, months to repair and plant stoppage are commonly used. In May of 2008, Koch Nitrogen commissioned a brand new 8100 rpm, 1500 hp turbo expander. This plant has 1...

The International Maritime Organization's (IMO) has adopted new emissions standards, MARPOL Annex VI, for large ships and their fuels in order to reduce air pollution from the global shipping industry. For the Sulfur Emission Control Area (SECA), including North Sea and California, starting from 1...

The need for filtration systems in scrubbing units has been well documented. Filtration provides the benefits of reduced hot spots in the regenerator reboiler, reduced heat exchanger fouling and reduction of foaming in the absorbers. This paper discusses thin-cake candle filter technology that is...

Benzene, toluene and xylene separation is a requirement for the production of the many valuable aromatic based materials used in consumer and industrial products. There are several options in performing these separations by distillation. This paper discusses the energy usage and capital cost...

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...
