摘要： Commercially valuable oil is recovered from refinery-produced, Resource Conservation and Recovery Act classified, hazardous waste oil sludges by a series of volatilizing and condensing steps (which may vary depending on the oil, water, and solids content of the sludge) resulting in the production of nonhazardous water and solid waste byproducts. A pumpable, low viscosity, high oil- and/or water-content sludge is first centrifuged to separate free oil and water, while the thick waste oil sludge, centrifuge solids, or other sludges low in oil and/or water content are heated to volatilize the contained water and oil. Dry, friable, deoiled solids are recycled with the oily sludge feed to prevent material agglomeration and heat exchanger fouling. Oil and water vapor from the high-temperature volatilization apparatus is recycled as an indirect heat source to the low-temperature volatilization apparatus. The volatilized oil and water are condensed and combined with the oil and water centrate, and the oil and water are essentially separated as by gravity in a settler. The separated oil is again centrifuged to remove any entrained water and solids. The nearly oil free, nonhazardous waste water and nonhazardous, deoiled solids can be disposed of in a conventional manner, and the commercially valuable recovered oil is suitable for further refinery processing.
摘要翻译：通过一系列挥发和冷凝步骤（根据污泥的油，水和固体含量可能会有所不同），从炼油厂生产的“资源养护和回收法”中回收了有价值的石油，从而导致了危险废油污泥生产非危险水和固体废物副产品。首先将可泵送，低粘度，高含油和/或含水污泥离心分离出游离油和水，同时将较厚的废油污泥，离心固体或其他油和/或含水量低的污泥加热至挥发含水和油。干燥，易碎，脱油的固体与油性污泥进料一起回收，以防止物质聚集和热交换器结垢。来自高温挥发装置的油和水蒸汽作为间接热源再循环至低温挥发装置。挥发的油和水被冷凝并与油和水分相结合，油和水在沉降器中基本上按重力分离。分离的油再次离心以除去所夹带的水和固体。几乎无油，无危险的废水和非危险的脱油固体可以以常规方式处理，并且商业上有价值的回收油适用于进一步的炼油加工。

摘要： There is disclosed an impedance-heated furnace for processing a nonflowable but conveyable material at the processing temperature comprising a nonrotating shell having electrical-conducting properties, and heated to a processing temperature using electrical impedance as the heat source. The shell includes an inlet and an outlet and a conveyor means, which also may be heated by impedance, for transporting or carrying the material along or through the shell. The resulting solids and any generated or volatilized gases are recovered separately.

A pumpable, low viscosity, high oil- and/or water-content sludge is first centrifuged to separate free oil and water. If the waste sludges are acidic or if nickel is present in the sludges in sufficient quantities so as to result in unacceptable levels in the TCLP leach filtrate, a base (such as calcium oxide) is admixed with the thick waste oil sludge, centrifuge solids, or other sludges low in oil and/or water content to render the sludges basic. The basic, admixed sludges are heated to volatilize the contained water and oil. Dry, friable, deoiled solids are recycled with the oily sludge feed to prevent material agglomeration and heat exchanger fouling. Oil and water vapor from the high-temperature volatilization apparatus is recycled as an indirect heat source to the low-temperature volatilization apparatus. The volatilized oil and water are condensed and combined with the oil and water centrate, and the oil and water are essentially separated as by gravity. The oil is separated from any entrained water and solids. The nearly oil free, nonhazardous waste water and nonhazardous, deoiled solids can be disposed of in a conventional manner, and the commercially valuable recovered oil is suitable for further refinery processing.
