Abstract: Wastesolution treatment systems and methods are provided which may remove particulates and hydrocarbons from wastesolution. Embodiments may be used to treat scrubber wastesolution from exhaust gas cleaning (“EGC”) systems. Some embodiments may be used with terrestrial EGC systems and others may be used for maritime ship EGC systems. Certain embodiments remove free phase oil and particulates from the wastesolution. Some embodiments may utilize a biogenerator cultured with hydrocarbon degrading microorganisms to reduce the concentration of oils in the water. Certain embodiments may utilize a clarifier and filtration unit to remove contaminants in the water. The wastesolution may be recirculated through the system until the measured contaminant concentration drops below a threshold value. The treated wastesolution may be stored, reused, or may be safely discharged from the system.

Abstract: A system for removing particulate matter from dirty air and producing cleaned air without the need for heating, cooling, or pressurization. The system uses a bubble tank with grates, a centrifuge connected to the bubble tank with grates, and a pH neutralization container connected to the centrifuge. A pH tester and base bins contain pH adjusting bases that can communicate with a processor and data storage. The system compares the measured pH of the centrifuged water to a preset limit in a library and then determines the amount of base and type of base to be added to the centrifuged water to produce clean water.

Abstract: The invention is a method of processing tarry or resinous liquids. Tarry liquids include wet scrubber liquids containing tars and chars derived from gasification, pyrolysis or drying of biomass. Resinous liquids include those derived from processing coniferous biomass. Tarry or resinous liquid is processed by a horizontal axis centrifuge having a discharge chamber containing a scraper to prevent centrifuge clogging or fouling. The removed tar and char can be used as solid fuel or recycled to the gasification or pyrolysis process. Polymers, for instance cationic polymers, can be added to the tarry or resin containing liquid prior to centrifugation to assist in solids/liquids separation. Removed resin can be recycled for further use. Tar, char or resin depleted wet scrubber liquid can be recycled for further use or more easily treated prior to disposal.
Abstract translation: 本发明是处理焦油或树脂液体的方法。 塔里液体包括湿法洗涤液，其中含有焦油和焦炭来自气化，热解或干燥生物质。 树脂液体包括来自加工针叶生物质的那些。 塔里木或树脂液体由具有包含刮板的排放室的水平轴离心机处理，以防止离心机堵塞或结垢。 去除的焦油和焦炭可以用作固体燃料或再循环到气化或热解过程中。 聚合物，例如阳离子聚合物，可以在离心之前加入到含有焦油或树脂的液体中以辅助固体/液体分离。 去除的树脂可以再循环使用。 沥青，炭或树脂贫化的湿式洗涤液可以在再处理之前再循环使用或更容易处理。
