摘要： Methods and systems for inhibiting buildup of crystalline materials in a flue gas desulfurization (FGD) unit. Crystalline materials can accumulate in FGD units as a byproduct of chemical desulfurization processes and can adversely impact FGD unit function. The systems described in the present application include an FGD unit with one or more selected bacterial strains disposed therein. It is believed that the bacteria may form a biofilm on the surfaces in the FGD and/or form a biosurfactant to inhibit or prevent buildup of crystalline materials in the FGD unit. Methods include inoculating an FGD unit with one or more selected bacteria that inhibit or prevent buildup of crystalline materials in the FGD unit. Methods may include periodic reinoculation of the FGD unit.

摘要： An apparatus and method to recover heat from and cool flue gases. As shown in FIG. 1, a condenser 10 is provided having two packed beds (20/26) and separate condensate loops. The condensate loops are configured such that first packed bed 20 maximizes heat recovery from flue gas 12 and second packed bed 26 maximizes cooling of flue gas 12. Temperature differences between entry flue gas 12 and recovered condensate 38 are minimized while temperatures differences between exit flue gas 34 and return condensate 54 is also minimized.

摘要： For exhaust gas recirculation in internal combustion engines operating, for example, with low sulphur marine diesel oil, an exhaust gas cooler with a cooling unit may be applied that uses a liquid injection system to maintain clean and/or clean a cooling surface of the cooling unit. The liquid injection system may provide liquid into an exhaust gas passage upstream of and or along a condensation starting region the cooling surface, thereby reducing the formation of films and deposits from particulate matter and condensing liquid of an evaporated liquid within the exhaust gas such as sulphuric acid and/or water, as those deposits could otherwise at least partially block the exhaust gas cooler.

摘要： Disclosed are methods and apparatus for treating and analyzing a gas stream to determine the effectiveness of urea gasification. The apparatus will be capable of performing the method and will include: means for introducing an aqueous solution of urea into a reactor having hot gases therein and subjecting the aqueous to temperatures for a time to assure the gasification of the aqueous urea and form a thermal gasification product stream containing NH3 and HNCO; means for taking a sample stream from the gasification product stream; means for contacting the sample stream with a hydrolysis catalyst in the presence of sufficient water to convert HNCO to NH3 and form an ammonia sample stream; and means for analyzing the ammonia sample stream for NH3. The methods and apparatus can also be used to control a urea gasification process and/or to signal anomalous operation.

摘要： Petroleous production is associated with effluents well known to foul lines, nozzles, and containers while consuming substantial energy to assist in both production and remediation. A heat exchanger and manifold system maximizes flows, minimizes changes in flow cross-section, and maximizes heat transfer area, while recycling both water and heat between processes. Dirty regions and clean regions result from scrubbing horizontal exhaust stacks and evaporation of production water in concert to remediate one another, while recycling a significant portion of the energy consumed by each. The heat exchanger relies on a manifold having many layered conduits, each connected to a single layer level of one or more cylindrical conduits in the exchanger. The cylinders of the exchanger themselves are arranged in multiple layers, each layer of a heat exchanger element being connected to a single layer of the manifold. Any shape of cylinder may work, but a right circular cylinder having corrugated sheets spacing the layers may be simple to construct.
