Benefits of technology

[0024] The present invention provides improved pyrolysis systems and methods that address a number of described drawbacks associated with the prior art.

Problems solved by technology

As stated, one major drawback of the prior art is the production of reaction water due to the presently used condensation methods and resulting need for three-phase centrifugal separation of oil, particulate matter and reaction water.
An additional drawback of the prior art is that conveyance of sludge through a reaction chamber occurred so slowly that the material was not mixed sufficiently during the process to allow sufficient contact between the sludge and vapors in the reaction chamber.
While this approach addre

Embodiment Construction

[0052] Industrial and municipal wastewater treatment plants produce significant amounts of sludge that must be properly treated for disposal. Thermal conversion processes such as pyrolysis can be used to convert sludge into bio-oil and char that can have a wide variety of commercial and industrial applications. However, prior approaches to these processes have suffered from many drawbacks. Some of these drawbacks include the creation of reaction water and the inability to independently control the mixing of sludge material within a reaction chamber and the time the sludge spends within the reaction chamber. This particular drawback requires that operation be conducted in batches whereby a batch of sludge material is fully processed before the quality of the resulting oil can be tested. This batch process is time consuming and, when adjustments are needed, requires that the entire pyrolysis process be shut down while manually actuated valves, screws, and other moving parts are adjust...

Abstract

Disclosed herein are systems and methods for thermal conversion of sludge into fuel and other products such as char. The systems and methods disclosed herein, among other benefits, convert sludge into fuel without the creation of reaction water and allow for the independent control of mixing and the movement of sludge through pyrolysis systems. Chars formed during pyrolysis have a number of beneficial uses.

CROSS REFERENCES TO RELATED APPLICATIONS [0001] The present application is a continuation-in-part of U.S. patent application Ser. No. 11 / 379,404, filed Apr. 20, 2006, which claims the benefit, under 35 U.S.C. § 119 of 60 / 675,511, filed Apr. 27, 2005, and of U.S. Provisional Patent Application Ser. No. 60 / 692,099, filed Jun. 20, 2005, and of U.S. Provisional Patent Application Ser. No. 60 / 695,608, filed Jun. 30, 2005, the contents of which are incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention relates to the thermal conversion of sludge and other organic / carbonaceous materials into energy and other products. BACKGROUND OF THE INVENTION [0003] Industrial and municipal wastewater treatment plants produce significant amounts of sludge, a material comprised of water, organic material (such as proteins, lipids and carbohydrates), and inorganic materials (such as clay and grit) that have not been eliminated during the treatment process. While most faciliti...
