Patent number: 7419296Abstract: A gel mixing system that employs a dynamic diffuser for quickly removing the air from the fluid as the fluid exits a traditional gel mixer and employs progressive dilution of the gel in a series of hydration tanks to maximize hydration time without allowing the gel to become so viscous that it is not easily diluted or pumped. High shear agitation of the fluid between the hydration tanks helps to increase the hydration rate. Progressive dilution of the gel increases residence time of the gel in the tanks and results in longer hydration time in the limited tank space available, resulting in continuous production of gel that is almost fully hydrated when it is pumped to the fracturing blender and subsequently to the well bore without the need for an increase in the volume of the hydration tanks.Type: GrantFiled: April 25, 2005Date of Patent: September 2, 2008Assignee: Serva CorporationInventor: Thomas E.

Patent number: 6024481Abstract: A mixer for liquid or suspensions comprises two mixing chambers each of which is provided with an outer inlet. The chambers are connected to each other in such a way that the first chamber leads to the second chamber. A number of mixing elements are arranged on a rotating axis which is common for the two chambers. The mixing elements have different shapes in the two chambers. In the first chamber the mixing elements are arranged to achieve mixing by means of large shear forces. In the second chamber the mixing elements are arranged to achieve mixing by stirring mainly without shear forces. A method for continuous mixing comprises mixing a little amount of a first liquid with a considerably larger amount of a second liquid in a first mixing chamber in which the mixing takes place by way of high shear forces. The obtained mixture is subjected to mixing by stirring mainly without shear forces in a second mixing chamber.Type: GrantFiled: July 9, 1997Date of Patent: February 15, 2000Assignee: Alfa Laval ABInventors: Anders Hillstrom, Peter Sjoberg

Patent number: 4953135Abstract: Disclosed is a method and apparatus for avoiding the clumping of dry fibers having diameters and lengths in certain ranges during blending of such fibers into a dry or wet particulate material. The process comprises distributing fibers in a vaporous medium, and transporting fluidized fibers to a mixing zone containing a dry or wet particulate material. Concurrently with stirring and blending of the particulate material with fluidized fibers, the fluidized fibers having been separated at least partially from a fluidized vapor are gradually introduced into the mixing zone. This process avoids the phenomena of "balling" that otherwise occurs with certain fibers.Type: GrantFiled: August 17, 1988Date of Patent: August 28, 1990Assignee: Ashland Oil, Inc.Inventor: Donald M.

Patent number: 4850704Abstract: A two stage blender is capable of handling high viscosity liquid-powder mixtures. The mixture discharged from the first stage is directed to the second stage, from which it is discharged at a relatively high discharge pressure. The second stage further enhances the natural vacuum created within the first stage, so that powder is fed at a constant ratio for a wide variety of liquid flows. Selected internal parts of the blender are designed to permit cleaning the blender in place.Type: GrantFiled: February 25, 1988Date of Patent: July 25, 1989Assignee: Ladish Co.Inventors: Robert D.

Patent number: 4786480Abstract: Present invention relates to two-part fluid contactors for application in fluid-fluid contacting processes such as liquid-liquid extraction processes used in nuclear fuel reprocessing. The contactor has a first part and a second part with a plurality of annular regions located between the first and second parts and a plurality of settling compartments disposed sequentially along the axis of rotation of the contactor. First and second fluids are introduced into the annular regions, and a mixture of the first and second fluids is transferred into the settling compartments. The first and second fluids substantially separate in the settling compartments and are then removed therefrom. The apparatus is arranged such that in operation the first and second parts may be moved relatively to one another so that conditions exist in the annular regions such that the first and second fluids disperse one within the other to form a mixture of fluids.Type: GrantFiled: August 25, 1986Date of Patent: November 22, 1988Assignee: United Kingdom Atomic Energy AuthorityInventor: Peter D.
