    • Heavy hydrocarbon containing sludges (10) such as refinery waste streams, oil storage tank sludges and marine oil tanker ballast are treated by passing the sludges in a flow stream through an indirect dryer (12) to vaporize liquids having a boiling point at atmospheric pressure of less than about 700°F and to provide substantially dried solid particles (22) discharged from the dryer. The dried particles, containing heavy hydrocarbons as a coating or as a part of the solids, are conducted to a combustor/oxidizer (62) and exposed to a high velocity flow stream of oxygen containing gas, typically low pressure forced air, to burn the residual hydrocarbons in the solids and to reduce heavy metals and the like to oxides thereof. A sludge handling system (9) includes a rotary disk type indirect dryer (12) connected to a lift pipe type combustor/oxidizer (62) for thorough exposure of the dried solids to an oxygen containing atmosphere. A centrifigal or cyclone type gas-solids separator (80)) receives the flow stream discharged from the lift pipe (64) and a portion of the dried solids (52) may be diverted after discharge from the dryer (12) back to the dryer inlet (18) to reduce the moisture content of the sludge flow stream introduced to the dryer (12) to minimize caking and clogging of the dryer (12) itself.
    • 通过使流动的淤泥通过间接干燥器(12)将含有重质烃的污泥(10)如炼油厂废物流,储油罐淤泥和海洋油罐车镇流器通过流化物流将淤浆(12)蒸发成沸点在大气压 小于约700°F,并提供从干燥器排出的基本干燥的固体颗粒(22)。 将含有作为涂层或作为固体的一部分的重质烃的干燥颗粒被传导到燃烧器/氧化剂(62)并暴露于含氧气体(通常是低压强制空气)的高速流动流中,以燃烧 固体中的残余烃,并将重金属等还原为其氧化物。 污泥处理系统(9)包括连接到提升管式燃烧器/氧化器(62)的旋转盘式间接干燥器(12),用于将干燥固体彻底暴露于含氧气氛。 离心式或旋风型气固分离器(80)]接收从提升管(64)排出的流动流,并且一部分干燥固体(52)可以在从干燥器(12)排放到干燥器 入口(18),以减少引入干燥器(12)的污泥流的水分含量,以最小化干燥器(12)本身的结块和堵塞。
