Including Temperature Change patent applications listed include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.

11/28/13 - 20130313202 - Process for the purification of iron salt solutions
A process is provided for removing metal salt co-constituents from an iron-containing solution comprising: (a) decreasing the free acidity of the solution to produce a slurry; (b) optionally heating the solution or the slurry to a temperature at least 30° C.; (c) optionally aging the slurry; (d) adding one or...

05/23/13 - 20130126439 - System and method of separating product from sludge in storage tanks
A system and method of removing product from sludge at a bottom of a storage tank that includes introducing a liquid to the tank, heating and agitating the liquid to separate the product from the sludge, and then removing the separated product and removing the introduced liquid....

08/16/12 - 20120205319 - Apparatus and method for discharge of treated sewage sludge from bins
Treated sewage sludge containing a flocculant is discharged from bottom of a bin, with the discharge being facilitated by heating sloped walls of the bin an amount sufficient to increase the ability of the sludge to slide along sloped bin walls. The flocculant in the sludge includes a polymeric material...

08/16/12 - 20120205320 - Desalination using supercritical water and spiral separation
The present application relates to systems and methods for the desalination of water. The systems and methods receive source water containing particles therein from a source of water such as, for example, the ocean. The source water may be pre-treated to remove suspensions and/or sub-micron organics in the source water....

05/24/12 - 20120125864 - Methods for reducing scale formation on and removing deposits from heat transfer surfaces
Disclosed are methods of operating steam generators, particularly evaporators, in hard water environments characterized by high Si and Mg content in which the pHcold of the feed water stream is maintained within a range of about 11 to 12 in order to reduce, eliminate or remove scale from internal evaporator...

05/12/11 - 20110108491 - Desalination using supercritical water and spiral separation
The present application relates to systems and methods for the desalination of water. The systems and methods receive source water containing particles therein from a source of water such as, for example, the ocean. The source water may be pre-treated to remove suspensions and/or sub-micron organics in the source water....

07/15/10 - 20100176064 - Back pressure-matched, integrated, environmental-remediation apparatus and method
Production brines are used to scrub a horizontal stack receiving exhaust from an energy source, controlling, reducing, or both noxious chemicals. Mutual remediation of flows from petroleous production cool and scrub exhausts from flares burning waste hydrocarbons, heaters lowering viscosity of crude oil, engines driving oil pumps or natural gas...

12/03/09 - 20090294377 - Method for removing dissolved solids from aqueous waste streams
A method for removing dissolved solids from a waste stream, such as that produced in flue gas scrubbing, through an evaporation-crystallization process operated at relatively low temperature. A waste stream is directed into an evaporator and heated at a temperature of less than 60° C. at a pressure below atmospheric...
