Publication number: 20210253984Abstract: Provided is a method of processing stillage from an ethanol production process. The method comprises treating stillage comprising oil, protein, and water upstream of a separation, concentration or evaporation step with at least one organic coagulant and at least one flocculant, thereby forming treated thin stillage comprising solids which include at least a portion of the oil and protein; and clarifying the treated stillage via a solid/liquid separation process thereby forming clarified stillage and a separated solids phase comprising at least a portion of the protein from the stillage.Type: ApplicationFiled: February 3, 2021Publication date: August 19, 2021Applicant: Ecolab USA Inc.Inventor: Lan Xiao

Patent number: 10782241Abstract: A method of detecting free flocculant polymer having a net charge present in an aqueous phase of a multi-phase substance is provided. The multi-phase substance comprises a solid phase, an organic phase, and the aqueous phase. The method comprises separating the solid phase from the multi-phase substance to form a dual phase top liquid comprising the organic phase and the aqueous phase; separating the organic phase from the dual phase top liquid, leaving the aqueous phase; combining the free flocculant polymer in the aqueous phase and a dye having an opposite net charge than that of the free flocculant polymer, thereby causing a spectroscopically observable change in the aqueous phase; and analyzing the aqueous phase via spectrometry to determine the concentration of the free flocculant polymer in the multi-phase substance.Type: GrantFiled: July 27, 2018Date of Patent: September 22, 2020Assignee: Ecolab USA Inc.Inventors: Hua Zheng, Xiaodong Huang, Tiandi Zhuang, Lan Xiao, Patrick G. Murray, Philip M. Eastin

Patent number: 10139385Abstract: The invention provides methods and compositions for utilizing encapsulated tracer dyes in difficult liquids such as wastewater or with highly reactive treatment chemicals such as aluminum-based coagulants. In difficult liquids or highly reactive treatment chemicals even so-called “inert” tracers end up reacting and their fluorescence changes. As a result they are inconsistent and cannot be used to measure the amount of treatment chemical present. But by encapsulating the tracer dyes, even non inert tracer dyes become inert and they can reliably be used to measure the amount of treatment chemical present even if highly reactive or in a difficult liquid.Type: GrantFiled: August 12, 2013Date of Patent: November 27, 2018Assignee: Ecolab USA Inc.Inventors: Lan Xiao, Yanjiao Xie

Patent number: 7789656Abstract: An injection molding device for thermosetting molding materials includes a male mold portion, and a female mold portion. The male mold portion includes an injection aperture and a sprue communicated with the injection aperture. The female mold portion is mated with the male mold portion to define a parting face therebetween and includes a cold slug well and a main runner. The cold slug well is disposed at an opposite end of the sprue relative to the injection aperture and has at least two inner sidewalls perpendicular to each other. The main runner is defined in the parting face and commutating with the sprue. The refractive index of the products molded using the injection molding device may be obtained via directly measuring that of the cold slug after molding. Therefore, the time spent to measure the refractive index of the products is less than the conventional method.Type: GrantFiled: June 27, 2008Date of Patent: September 7, 2010Assignees: Premier Image Technology(China) Ltd., Hon Hai Precision Industry Co., Ltd.Inventor: Lan Xiao
