Abstract: The present invention provides novel techniques for controlling the output of a distillation sub-process by controlling, using model predictive control, the temperature of steam used in the distillation sub-process, wherein the steam is generated in a milling and cooking sub-process. In particular, the present techniques are presented in the context of biofuel production, wherein the temperature of a cook tube generated in a milling and cooking sub-process may be controlled to optimize the energy utilization in the ethanol/water separation of a side stripper column, which uses the cook flash steam as an energy source. However, the present techniques may also be applied to other suitable applications, such as liquor processing, where steam generated in a different process may be used in a distillation process to help separate water from the liquor.
Abstract: According to some embodiments, the present provides a heat transfer medium that includes, but is not limited to a base fluid, a plurality of single-walled carbon nanotubes, and a gelling formulation formed of an amine surfactant, an intercalating agent, and an oxygen-bearing solvent. The heat transfer medium is adapted for improved thermal conductivity with respect to the base fluid.

Abstract: A firelighter composition comprises a mixture of a liquid hydrocarbon and lignite. The liquid hydrocarbon preferably comprises kerosene. It has been found that lignite has the effect of extending the bum time and lowering the flame height, thereby increasing the combustion efficiency for a given weight of firelighter.
