Low-cost extraction of maize protein using ethanol at the front end of a dry grind ethanol plant has been discussed in recent articles. Thorough recovery of (alcoholic) extract from the extracted maize is essential to make the process economical and to prevent the ethanol from interfering with liquefaction enzymes or fermentation organisms where the solid residues are to be subsequently reduced...

Unlocking oil from tight reservoirs remains a challenging task, as the existence of fractures and oil-wet rock surfaces tends to make recovery uneconomic. Injecting gas in form foam is considered feasible technique such for providing conformance control reducing gas-oil interfacial tension (IFT) that allows injected fluids enter matrix. This paper presents modeling strategy aims understand beha...

in this work the likelihood of asphaltene deposition problems during dynamic displacement of oil by natural gas in unconsolidated porous media is experimentally inspected. the two different rock materials, limestone and sandstone, are used as a representative of porous media. dynamic flow experiments indicate that the increase of natural gas injection increases asphaltene deposition in the unco...

Development of the new, insensitive, energetic compound, NTO (3-nitro-1,2,4-triazol-5-one), creates need for the data on NTO's fate and transport to predict its behavior in the environment and potential for groundwater contamination. To measure the transport of NTO in soils, we conducted miscible-displacement experiments under steady state and interrupted flow conditions using eight soils havin...
