An experimental method of oil-containing
sludge heat treatment is applicable to research of oil-containing
sludge heat
treatment effect and characteristics. The programmed heating process comprises the following steps of: firstly,
desiccation treatment, wherein an oil-containing
sludge sample is heated from
room temperature to 200-250 DEG C to realize complete
moisture evaporation, and the composition of non-condensable gas and recovered oil is analyzed; secondly,
pyrolysis treatment, wherein the desiccated
oil sludge is heated to 600-700 DEG C to realize complete
pyrolysis of organic substances such as heavy oil,
asphaltene and the like in the
oil sludge by high-temperature heating, and the composition of recovered oil and non-condensable gas is analyzed; thirdly,
calcination treatment, wherein the oil-containing sludge pyrolytic residues are heated to 800-900 DEG C, and the content of pollutants such as
petroleum and the like is analyzed. The method is convenient and rapid for the obtaining of the yield and composition data of heat treatment products of the oil-containing sludge at different
heating temperature phases, and for the research and mastering of the heat
treatment effect and characteristics of oil-containing sludge, and can realize the purpose of harmless and
resource utilization of oil-containing sludge.
