Abstract: A method is provided for measuring an electrolytically-active species concentration in an aqueous or non-aqueous solution for use in providing control of the concentration of the species in a source solution thereof based on the measurements. In the method, a sample containing an electrolytically-active species is added into a measurement cell that has a working electrode and an auxiliary electrode, and a constant current is applied to the measurement cell while the working and auxiliary electrodes are in contact with the sample with monitoring of voltage difference across the electrodes until a change in the voltage difference is detected. A feedback signal is generated based on a parameter of the change in the voltage difference that is directly proportional to the amount of the electrolytically-active species in the sample, which can be used for process control. An apparatus is also described.

Abstract: A method and system for improving ethanol production from biomass are provided which includes adding at least one separation aid to stillage, that is preferably whole stillage, that contains oil and/or fat generally in the form of an emulsion, to form a treated stillage prior to centrifuging the stillage, and centrifuging the treated stillage in at least one centrifuge to separate at least a portion of the solids content from the treated stillage. The separation aid contains at least one anionic surfactant, at least one non-ionic surfactant, at least one organic solvent that is miscible in water, and water, and optionally at least one lecithin. Treated stillage products are also provided which can contain the indicated separation aid.
