Title: Flotation machine and process for removing impurities from coals

Full Record
Other Related Research

Abstract

The present invention is directed to a type of flotation machine that combines three separate operations in a single unit. The flotation machine is a hydraulic separator that is capable of reducing the pyrite and other mineral matter content of a coal. When the hydraulic separator is used with a flotation system, the pyrite and certain other minerals particles that may have been entrained by hydrodynamic forces associated with conventional flotation machines and/or by the attachment forces associated with the formation of microagglomerates are washed and separated from the coal.

Flotation process for removal of precipitates from electrochemical chromate reduction unit

Patent DeMonbrun, James R [Knoxville, TN]; Schmitt, Charles R [Oak Ridge, TN]; Williams, Everett H [Oak Ridge, TN]

This invention is an improved form of a conventional electrochemical process for removing hexavalent chromium or other metal-ion contaminants from cooling-tower blowdown water. In the conventional process, the contaminant is reduced and precipitated at an iron anode, thus forming a mixed precipitate of iron and chromium hydroxides, while hydrogen being evolved copiously at a cathode is vented from the electrochemical cell. In the conventional process, subsequent separation of the fine precipitate has proved to be difficult and inefficient. In accordance with this invention, the electrochemical operation is conducted in a novel manner permitting a much more efficient and less expensivemore » « less

Process for removing polymer-forming impurities from naphtha fraction

Patent Kowalczyk, Dennis C [Pittsburgh, PA]; Bricklemyer, Bruce A [Avonmore, PA]; Svoboda, Joseph J [Pittsburgh, PA]

Polymer precursor materials are vaporized without polymerization or are removed from a raw naphtha fraction by passing the raw naphtha to a vaporization zone (24) and vaporizing the naphtha in the presence of a wash oil while stripping with hot hydrogen to prevent polymer deposits in the equipment.
