  • Publication number: 20180105757
    Abstract: A method of correcting measurements of a chemical sensor used in an industrial facility. The method involves correcting for errors known to occur in the steady state and the dynamic state for specifically recognized situations. This method allows for correcting errors that occur due to deadtime, false zero measurements, and non-linear disturbances. The method combines automated measurement techniques and human know how to progressively learn and refine the accuracy of the corrections.

  • Publication number: 20170348615
    Abstract: The invention provides a method and apparatus for reducing the energy needed to process stillage in an ethanol refining operation. The method involves adding to stillage an effective amount of at least one processing aid. The flocculant induces the separation of insoluble material that would otherwise remain suspended in water but which impose a high shear energy cost on the refining processes. This allows for the removal of insoluble material that would otherwise be overlooked but which increase energy costs. This allows for more efficient and effective separation and recovery of insoluble fractions of the concentrated thin stillage that would otherwise be overlooked and lost in the process. Loss of these valued fractions as a result of traditional processing techniques and those requiring extensive additional energy input results in the loss of high value co-products to low revenue process streams.

  • Publication number: 20170204342
    Abstract: A method of optimizing system parameters in a crude unit to reduce corrosion and corrosion byproduct deposition in the crude unit is disclosed and claimed. The method includes measuring or predicting properties associated with the system parameters and using an automated controller to analyze the properties to cause adjustments in the chemical program to optimize the system parameters. Adjusting the system parameters effectively controls corrosion in the crude unit by reducing the corrosiveness of a fluid in the process stream and/or by protecting the system from a potentially corrosive substance. System parameter sensing probes are arranged at one or more locations in the process stream to allow accurate monitoring of the system parameters in the crude unit.

  • Patent number: 9683935
    Abstract: The invention is directed towards methods and compositions for identifying the presence of surfactants in water. The invention is quite superior over the prior art because it can form a colorful complex in half the time, avoid the need for difficult separation steps, use a safer solvent, and avoid the formation of messy foam. The invention involves adding to the water a cobalt thiocyanate reagent, pre-prepared from a cobalt salt and a thiocyanate salt, which forms a colorful complex with the surfactant. Chloroform is then added to the water. The cobalt reagent causes the virtually all of the surfactant to form a colored complex which rapidly migrates into the chloroform and prevents the surfactant from foaming. Once in the chloroform, a UV-vis spectrometer can easily and precisely identify the type and amount of surfactant that was in the water.

  • Patent number: 9574429
    Abstract: Air and ammonia gas are introduced into a subterranean formation during the in-situ combustion to increase the mobility of hydrocarbons in a subterranean formation and facilitate recovery of the hydrocarbons from the subterranean formation. The air supports in-situ combustion of a portion of the hydrocarbon within the subterranean formation to form water and establish a combustion front. The ammonia gas contacts the hydrocarbons ahead of the combustion front and reacts in-situ with naphthenic acid in the hydrocarbon to form a surfactant. The hydrocarbons, water and surfactant then form an oil-in-water emulsion that drains more freely through the formation. A production well, in fluid communication with the hydrocarbons ahead of the combustion front, may be used to remove the oil-in-water emulsion from the subterranean formation.

  • Patent number: 9562861
    Abstract: A challenge in using recycled material in the papermaking process is the presence of hydrophobic organics with adhesive properties commonly known as “stickies.” Hydrophobic agglomerates can result in spots or defects in the final paper product or deposit on papermaking equipment resulting in poor runnability and downtime. Technologies for monitoring and controlling microstickies exist. However, a need exists for a technique to rapidly determine the size and content of macrostickies (diameter>100 microns) in recycled pulp process streams. The present invention is a device and method to perform real-time macrostickies and/or any visible hydrophobic particle analysis in an aqueous medium. Using the present invention, furnish quality can be monitored and treatment performance can be monitored and controlled. The technique is based on fluorescence image analysis to identify and count sticky particles as well as measure their size.
