Provided are systems and related methods for processing organic polymeric feed materials—such as plastics—to form pyrolysis oil. The disclosed systems can be operated in a continuous manner and utilize novel liquid-solid separation techniques integrated with a novel condensing approach so as to operate in a product-efficient and an energy-efficient manner.

A method of processing thin stillage in an ethanol refining operation is provided. The method comprises treating thin stillage upstream of a concentration or evaporation step with an aid comprising a sorbitan ester of a fatty acid, an ethoxylated sorbitan ester of a fatty acid, or a combination thereof, thereby forming treated thin stillage. The aid may include at least one of sorbitan monooleate, polyoxyethylene sorbitan monostearate, and polyoxyethylene sorbitan monolaurate.

Techniques for monitoring a well clean-up process are disclosed. In one embodiment, a method includes routing a multiphase fluid having oil and water to a separator of a well testing apparatus, separating the multiphase fluid into separate fluids via the separator, and routing the separated fluids away from the separator. The method also includes measuring flow rates of oil and water leaving the separator and determining individual flow rates of oil and water entering the separator as part of the multiphase fluid based on the measured flow rates of oil and water leaving the separator. Additional systems, methods, and devices are also disclosed.

A method for producing epoxyalkane includes the step of separating, in a separation column, a stream containing epoxyalkane, extractant, and diol. The separation column operates under conditions so as to enable the extractant and the diol to form an azeotrope, and a stream containing extractant and binary azeotrope is extracted from the side-draw of the separation column to liquid-liquid separation. The method can be used for the industrial production of epoxyalkane.

A food processing system includes at least one receptacle containing a composition of water and insoluble solids, a centripetal force-based solid/liquid separator having an inlet, a solids outlet, and a liquid outlet, and a pump able to direct the composition from the receptacle to the inlet of the separator. The separator is configured to separate the composition into a solids stream including the insoluble solids and a liquid stream including water and to direct the solids stream through the solids outlet and the liquid stream through the liquid outlet.

A separation system includes an elongated separator vessel having an inlet, a heating section which is located downstream of the inlet, an oil accumulation section which is located downstream of the heating section, and an oil outlet which is connected to the oil accumulation section. The heating section includes an immersed plate heater which is fluidly connected to a heating medium heater that is located externally of the separator vessel. In operation, a heating fluid which is heated in the heating medium heater is circulated through the immersed plate heater to heat the multiphase fluid.

A process for the hydroconversion of heavy oil products includes the following steps where heavy oil products and hydrogen are supplied to a slurry hydroconversion section having a molybdenum-based catalyst: separating the reaction effluent into a vapour phase and a slurry phase; and sending the slurry phase to a separation section having the function of separating the Vacuum Gas Oil, Heavy Vacuum Gas Oil, Light Vacuum Gas Oil, and Atmospheric Gas Oil fractions, from a stream of heavy organic products which contains asphaltenes, unconverted feed, catalyst, and solid formed during the hydroconversion reaction. This stream is partly sent to the reaction section and partly forms a purge stream, which is heated and made fluid between 185° C.-220° C., and subjected to a static settling unit up to at least 100° C. From the settling unit two new products, clarified component and cake, are obtained. The clarified component is recycled to the hydroconversion reaction section.

A device and a method for removing fats, oils and/or grease (“FOGs”) from water comprise a separator, wherein the separator removes the FOGs that separate from the water under gravity, and a filter wherein the filter removes the FOGs remaining in the water after the water has passed through the separator. The filter comprises several layers having different compositions suitable for removing FOGs from water, including a layer comprising granular activated carbon bonded together and wrapped in polyester.

A smart sand includes raw sand particles, synthetic SiO.sub.2 particles attached to the raw sand particles, a first material attached to a first set of the synthetic SiO.sub.2 particles, a second material attached to a second set of the synthetic SiO.sub.2 particles, and a third material attached to the first material. Each of the first to third materials is different from each other.

A grease interceptor and method of use thereof is provided for separating solids, fats, oils, and grease waste (“F.O.G.”), and other particulate matter. The grease interceptor receives waste water in a liquid storage area where solids in the waste water have residence time long enough to gravitationally separate towards the bottom of the liquid storage area and waste that is less dense than water floats to the top of the liquid storage area. A series of features including channels, interrupter plates, and walls can increase the residence time or otherwise improve the separation of waste from the water. In addition, embodiments of the grease interceptor can have tapered access holes that improve visual inspection of the liquid storage area of the grease interceptor.
