Publication number: 20200016553Abstract: The present invention relates to an in-line mixing apparatus and use therein for adding a polymer solution and dewatering an aqueous mineral suspension. Said method comprises statically mixing the aqueous mineral suspension with a poly(ethylene oxide) (co)polymer to form a dough-like material. The viscous mixture material is then dynamically mixed in an in-line reactor to reduce the mixture viscosity and to form microflocs and release water. Said method is particularly useful for the treatment of suspensions of particulate material, especially waste mineral slurries, especially for the treatment of tailings and other waste material resulting from mineral processing, in particular, the processing of oil sands tailings.Type: ApplicationFiled: September 23, 2019Publication date: January 16, 2020Inventors: Paul A. Gillis, Jason S. Moore, Billy G. Smith, Michael D. Cloeter, Michael K. Poindexter, Irfan Khan

Publication number: 20170247271Abstract: The present invention relates to a method for flocculating and dewatering oil sands fine tailings. Said method comprises mixing the aqueous mineral suspension with a poly(ethylene oxide) (co)polymer to form a dough-like material. The material is then dynamically mixed in an in-line reactor to break down the dough-like material to form microflocs having an average size of 1 to 500 microns, and to release water. The internal diameter of the in-line reactor is at most five times the internal diameter of the inlet pipe of the reactor. The suspension of microflocs has a viscosity of at most 1000 cP and a yield stress of at most 300 Pa.Type: ApplicationFiled: July 31, 2015Publication date: August 31, 2017Applicant: Dow Global Technologies LLCInventors: Paul A. Gillis, Jason S. Moore, Billy G. Smith, Michael D. Cloeter, Michael K. Poindexter, Carol E. Mohler, Wu Chen, Cole A. Witham, Justice Alaboson, Shankhadeep Das, Harpreet Singh

Patent number: 9700855Abstract: A mixer for a continuous flow reactor and methods for forming the mixer and the operation thereof. The mixer allows for segmentation of a primary reactant flow through a plurality of ports into many smaller flows that are injected as jets into a secondary reactant flow in channels of the mixer. The channel has a constant width dimension to enhance even flow distribution and local turbulence of the primary and secondary reactant flows. The constant width dimension of the channel and the size and number of the ports of the mixer can be configured to ensure the primary reactant flow injected into the channel directly impinges on a surface of the channel that is opposite the injection point at normal operating conditions.Type: GrantFiled: August 11, 2014Date of Patent: July 11, 2017Assignee: Dow Global Technologies LLCInventors: Gene W. Bachman, Raymond M. Jones, Michael D. Cloeter, Charles W. Lipp, Mark J. Bartel, Brady J. Coomes, Scott J. Daigle, Steve F. Janda

Publication number: 20170056846Abstract: A static mixer (10) for combining a first fluid and a second fluid. The static mixer (10) including a plurality of plates (18, 24, 32, 40) having orifices (20, 26, 28) formed therethrough. As the first fluid and the second fluid pass through the static mixer (10), the fluids are combined and mixed.Type: ApplicationFiled: May 8, 2015Publication date: March 2, 2017Inventors: Zhao Yu, Michael D. Cloeter, Joy L. Mendoza, Philippe P. Maillot, Stacy W. Hoy, IV

Patent number: 9545606Abstract: Embodiments of the present disclosure include a process and a system for solubilizing a surfactant in supercritical carbon dioxide that include providing a turbulent flow of the supercritical carbon dioxide into which the surfactant solubilizes and injecting the surfactant into the turbulent flow of the supercritical carbon dioxide to achieve a Jet Mixing Number of 0.01 to 1.0. In one or more embodiments, a pump provides turbulent flow to supercritical carbon dioxide moving through at least a portion of piping, and an injector associated with the piping conveys the surfactant through surfaces defining a port in the injector to inject the surfactant into the turbulent flow of the supercritical carbon dioxide so as to achieve the Jet Mixing Number of 0.01 to 1.0.Type: GrantFiled: June 3, 2011Date of Patent: January 17, 2017Assignee: Dow Global Technologies LLCInventors: Michael D. Cloeter, Raymond M. Jones
