Publication number: 20130148462Abstract: A composition comprising a fluid, and a material dispersed in the fluid, the material made up of particles having a complex three dimensional surface area such as a sharp blade-like surface, the particles having an aspect ratio larger than 0.7 for promoting kinetic boundary layer mixing in a non-linear-viscosity zone. The composition may further include an additive dispersed in the fluid. The fluid may be a thermopolymer material. A method of extruding the fluid includes feeding the fluid into an extruder, feeding additives into the extruder, feeding a material into the extruder, passing the material through a mixing zone in the extruder to disperse the material within the fluid wherein the material migrates to a boundary layer of the fluid to promote kinetic mixing of the additives within the fluid, the kinetic mixing taking place in a non-linear viscosity zone.Type: ApplicationFiled: February 1, 2013Publication date: June 13, 2013Applicant: ECOPURO, LLCInventor: ECOPURO, LLC

Publication number: 20130146685Abstract: A system is for conditioning drill cuttings contaminated with hydrocarbons comprises an auger device for feeding an agitation chamber in which the material is washed and separated. The material is conditioned in the agitation chamber by a first conditioning agent for separating the hydrocarbon from the material. The material is crushed to a specific mesh size for further washing and conditioning using a second conditioning agent. The crushed material is then sent to a series of agitation and wash tanks wherein it is serially washed and conditioned until an acceptable concentration of hydrocarbon is achieved. The material can then be disposed.Type: ApplicationFiled: December 6, 2012Publication date: June 13, 2013Inventor: LARRY SAIK

Patent number: 8439283Abstract: Methods and systems for enhancing fluidization of nanoparticle and/or nanoagglomerates are provided. A fluidization chamber is provided with a fluidizing medium directed in a first fluidizing direction, e.g., upward into and through a bed containing a volume of nanoparticles and/or nanopowders. A second source of air/gas flow is provided with respect to the fluidization chamber, the secondary air/gas flow generally being oppositely directed relative to the fluidizing medium. Turbulence created by the secondary gas flow is advantageously effective to aerate the agglomerates and the shear generated by the jet is advantageously effective to break apart nanoagglomerates and/or reduce the tendency for nanoagglomerates to form or reform. A downwardly directed source of secondary gas flow located near the main gas distributor leads to full fluidization of the entire amount of powder in the column.Type: GrantFiled: January 30, 2012Date of Patent: May 14, 2013Assignees: New Jersey Institute of Technology, Orion Engineered Carbons GmbHInventors: Robert Pfeffer, Jose A.
