Patent number: 9821320Abstract: An emissions reduction stack includes a conditioning section, collector section utilizing a Wet Electrostatic Precipitator (WESP), and output section. A chemically active aqueous stream is introduced into an incoming process stream in order to saturate the stream and produce a fog stream wherein water is condensed on the surface of particulates. The process of condensation increases the efficiency of the particulate filtration process conducted by the WESP.Type: GrantFiled: July 28, 2014Date of Patent: November 21, 2017Assignee: RSR TECHNOLOGIES, INC.Inventors: Timothy W.

Patent number: 8714361Abstract: Materials in battery and electrochemical cells are separated in a form suitable for recycling by employing froth flotation techniques. Bulk materials, such as casings, are removed from converted battery scrap and the resultant pulp is subjected to froth flotation. Froth flotation agents, including frothers, collectors and/or depressants, are used to manipulate the hydrophilic and hydrophobic nature of the materials in the scrap. Hydrophobic materials are entrained in the air bubbles of the froth and float out of the froth flotation vessel while those that are hydrophilic remain in the vessel, thereby separating battery grid materials without resort to pyrometallurgical, energy intensive or other environmentally undesirable processes.Type: GrantFiled: May 10, 2010Date of Patent: May 6, 2014Assignee: RSR Technologies, Inc.Inventor: Timothy W.
