Abstract: Systems and processes provide for a thermal process to transform sludge (and a variety of other natural waste materials) into electricity. Dewatered sludge and other materials containing a high amount of latent energy are dried into a powdered biofuel using a drying gas produced in the system. The drying gas is recirculated and is heated by the biofuel produced in the system, waste heat (from turbines or internal combustion engines), gas (including natural gas or digester gas) and/or oil. The biofuel is combusted in a boiler system that utilizes a burner operable to burn biofuel and produce heat utilized in a series of heat exchangers that heat the recirculating drying air and steam that powers the turbines for electricity production.

Abstract: Integrated systems and processes are provided for drying and milling sludge and other natural waste using waste heat extracted from reheated gas through an air-air heat exchanger process. In one example, the sludge or natural waste may be dried into a powder using high-temperature gas to absorb moisture from the sludge, causing the high-temperature gas to become an at least partially saturated gas. The at least partially saturated gas may pass through a separator- scrubber cycle before a first portion is heated in an air-heater and then used to heat a second portion of the at least partially saturated gas in an air-air heat exchanger. The heat for the air-heater may be provided by a burner operable to burn the dried powder obtained from the sludge. The heated second portion of gas may be used to dry and mill the sludge and other natural waste.

Abstract: A method of predicting at least one physical change in crack geometry of a crack in a pipeline based on in-line inspection operating pressure is presented. In one method, a first test on a pipeline is performed at a first pressure, which obtains a first set of test data. A second test is performed on the pipeline at a second pressure, obtaining a second set of test data. The first and second sets of test data are compared for any difference. A run comparison software processing device may be employed. In other methods, finite element analysis of crack-like dimensions is performed to predict Crack Mouth Opening Displacement (CMOD) for a given set of crack dimensions for a surface-breaking crack and inline pipe inspection operating run pressure. Another method predicts probability of detection of a crack associated with a given CMOD as a function of pressure in successive inspections.

Abstract: A ceramic fuel cell(s) is supported in a heat conductive interconnect plate, and a plurality of plates form a conductive heater named a stack. Connecting a plurality of stacks forms a stick of fuel cells. By connecting a plurality of sticks end to end, a string of fuel cells is formed. The length of the string can be one thousand feet or more, sized to penetrate an underground resource layer, for example of oil. A pre-heater brings the string to an operating temperature exceeding 700° C., and then the fuel cells maintain that temperature via a plurality of conduits feeding the fuel cells fuel and an oxidant, and transferring exhaust gases to a planetary surface. A manifold can be used between the string and the planetary surface to continue the plurality of conduits and act as a heat exchanger between exhaust gases and oxidants/fuel.
